Don't Settle for Less

Ellenex sensors support all major LPWAN technologies like NB-IoT, LoRaWAN and Low Power Satellite. We also manufacture devices for Wirepas on request.

All our products are designed with industrial applications in mind. Our sensors can reliably measure and securely transmit information about pressure, level, temperature, distance, flow and water quality. We also offer sensor interfaces to connect legacy and specialized devices to the internet using LPWAN technologies.

We have a custom product division that will take care of manufacturing devices specifically for you. Please feel free to get in touch with our client growth team and they will assist you with the entire process.

Ellenex sensors can receive commands over the air for changing sampling rates.

We offer single and multi channel sensor interfaces that use standard interfaces to communicate and receive data from your sensors and transmit it using LPWAN technologies.

Ellenex Sensors are designed to measure ranges from 0.5bar to 1000bar depending upon the application. Please visit our pressure sensors page for more information https://www.ellenex.com/ellenex-pressure-sensors

Ellenex Pressure sensors are rated at ±0.01 %Span unless otherwise specified. Please check the datasheet for more information.

The best method is to clean the sensor with cotton dipped in luke warm water or alcohol if there is no grease. Please make sure you have given enough time to dry before installing the sensor back after maintenance.

The main factors that may contribute towards sensor inaccuracies are: Operating temperature Shock & Vibration Overpressure

The maximum pressure that can be applied without changing the device's performance within the specifications varies from sensor to sensor. In the case of a standard PTS2 model, the proof pressure is 1000 bar.

Ellenex Level sensors are rated at ±0.01 %Span unless otherwise specified. Please check the datasheet for more information.

The main difference between submersible and ultrasonic level sensors is the measurement technique. In submersible sensors, the sensor head is immersed close to the floor of the tank or container. In Ultrasonic sensors, the sensor measures the distance between the top and fluid level. Ultrasonic sensors are useful for situations where the liquid level is unknown or the flow is too high and can damage wires Eg: flood water. Submersible sensors are useful for monitoring levels in water tanks, diesel tanks etc

You can use our PLC series for any liquid medium that is corrosive.

The best method to clean our sensors is by wiping them with cotton dipped in lukewarm water. Make sure the sensor is fully dried before installing it back again.

The primary cause for inaccurate readings might be the sensor not being oriented properly or tilted at a certain angle instead of perpendicular to the ground.

Our sensor accuracy depends on the chosen class. IEC 60751 ClassB (+/-0.12% or+/-0.3°C at 0°C) ClassA (+/-0.15°C at 0°C) Class1/3DIN (+/-0.08°C at 0°C) Class1/10DIN (+/-0.03°C at 0°C)

The range of our temperature sensors depends upon the device model. Our standard TTS2 has a rage of -50°C to 250°C

It depends on how well the sensor is placed into the measuring medium. A well-installed sensor would be less affected by external environment temperature as long as the medium is appropriately isolated.

Our standard temperature sensors are not corrosive resistant, but we can make temperature sensors that are corrosive resistant upon request. Please get in touch with our support team for more information.

You can place our temperature sensors in drinking water. Please clean the sensor and wire properly with cotton dipped in lukewarm water before installation.

We have a range of sensors measuring different water parameters. Please check the datasheet of the respective sensor to get more information about the sensitivity.

Yes, you can use water quality sensors in water containing minerals

Temperature, Vibration, and Impurities are a few of the external factors that may cause the accuracy of the sensors to drop. Please ensure that the temperature is suitable for the sensing application, there are no unnecessary vibrations and clean the sensor head regularly to prevent solid particles from entering.

NB IoT is also called as Narrowband IoT is a communication technology that relies on existing cellular network infrastructure to receive and transmit data. It has very low bandwidths allocated compared to traditional mobile phone speeds. It is a very reliable form of communication that doesn't need too many upfront costs for additional hardware.

Cat-NB and Cat-M1 are two different types of NB-IoT communication technologies. They differ in terms of available bandwidth for transmission. NB IoT / Cat-NB has less than 100Kbps of bandwidth available Cat-M1 has around 300-400Kbps of bandwidth available Power consumption is also higher in Cat-M1 as it uses higher frequencies to enable a higher data rate Another advantage of Cat-M1 is that it supports cell tower handover - the connection will be maintained when the device is on the move and comes into the range of a new tower. NB-IoT will drop the connection.

MQTT is a lightweight publish/subscribe messaging protocol designed for M2M (machine to machine) telemetry in low bandwidth environments

All Ellenex NB-IoT products can transmit and receive data using MQTT. Our devices were tested and used with AWS IoT Core, Azure IoT Hub & many more third party MQTT brokers.

Ellenex Platform can interact with our devices on a proprietary UDP protocol to save battery with extremely low bandwidth usage. You can get a considerably long usage from a single charge. MQTT is considerably heavier than UDP. You can use Ellenex Platform API to get the best of both worlds. Devices use UDP to communicate with Ellenex and you can use REST API to retrieve the data to any platform of your choice.

Our devices can communicate with any standard MQTT 3.1.1 broker, but over the years, we have identified a few services that work well with our devices and wanted to list them for reference. AWS IoT Core Azure IoT Hub (Does not support DPS yet) EMQX Dedicated / BYOC (Not Serverless) Any standard Eclipse Mosquitto server This list is non-exhaustive, and we will be adding more services as and when we test and validate new providers.

The information we need depends on your service provider. Below is a list of things that we need for any MQTT broker. Broker Address: Port: DeviceName / ClientID: Username: Password: PublicTopic (for device data): CommandTopic (for receiving downlink commands): QoS: Message Retention: SSL Level: CA Certificate file // Only if you need SSL or use a non-standard certificate Device Certificate file // Only if you don't want to use Username / Password authentication Private Key file // Only if you don't want to use Username / Password authentication Sharing private keys over email is an extremely unsecure process, and we suggest you use a CA and sign the CSR we provide so the private key is only on the device and not in multiple places.

Ellenex devices can record and transmit at different intervals to optimize battery life and network on time. This is only possible in certain network configurations. Please contact our client growth team to confirm availability for your specific application.

We can program Ellenex devices to act based on events. An event would be when water level reach 2 meters and the device triggers an uplink to the connected platform for alerts or further processing.

NB-IoT is the best option for applications that don't move over a long period of time and send smal amounts of data. Eg: Water meters, gas meters etc

You can check the coverage and the different operators using the following link: https://www.gsma.com/iot/mobile-iot-commercial-launches/

Yes, you can use any Cat-NB or Cat-M sim cards with Ellenex NB-IoT devices. We will need some information regarding your sim provider to configure the device. Ideally, we suggest using our sim cards that work globally on most network providers.

Name of the network provider: Connection type: Cat-M1 or NB-IoT? Network APN: Frequency Band(s) number/name: Scrambling status: enabled or disabled. Mobile Country Codes (MCC) / Mobile Network Codes (MNC) number of the provider: Authentication type (none/PAP/CHAP):

The LoRaWAN® specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services. Here is a short video explainer from SemTech the company behind LoRa

LoRaWAN devices operate in different classes based on the transmission requirements. Class A: Device sends an uplink, waits for a downlink in two short intervals and then goes to low power mode of operation. This is the default LoRa mode and is advantages for sensors that send data every few hours and stay in sleep mode. Downlinks can reach the device with very high latency and are not deterministic Class B: Devices are synchronised with the the network server using periodic pings and the latency of downlink communication is deterministic but at the cost of some additional battery consumption. It is still not an instant downlink transfer. Class C: Devices in Class C are always open to downlink commands unless they are transmitting. Network server can initiate a transmission at any time and the latency for downlink is very low. It is not suitable for battery operated devices as the receiver is always on. Devices in Class A switch over to Class C intermittently to support use cases like Firmware updates.

Class A by default, other classes on request.

A certain set of radio regulations, and the appropriate frequency plans should be used for different regions and countries. More details can be found at LoRa Allianace or The Things Network website

Due to the limitation on packet size and using stand-alone devices on battery, this technology is not suggested for tasks that require large amounts of data to be transmitted over a short period of time.

There are radio regulations that define the appropriate frequency plans to be used for the network servers in the respective countries. This is not an official document; gateway owners are still obliged to find, study and adhere to their own country’s regulations. TTN website has provided a detailed list of frequencies for different countries at this link: FREQUENCY PLANS

ADR (Adaptive Data Rate) is a feature, which is used to adapt and optimise the following parameters of a static end-device: Data rate, Tx power level Channel mask The number of repetitions for each uplink message The end-device decides to enable ADR. Once ADR is requested by the end-device, the network can optimize the end-device’s data rate, Tx power, channel mask and the number of repetitions for each uplink message.

LoRaWAN is designed with low-power and low data rate applications in mind. This comes as its biggest advantage and limitation. Devices last much longer compared to NB IoT on a single charge but at the same time packet size and transmissions are limited. LoRaWAN needs additional hardware called gateways to communicate with devices whereas NB IoT is plug-and-play.

27 kbps

1.0.2

In LoRaWAN any data generated by the device and sent to the user is called an Uplink message and any data send by the user to the device is called a downlink message.

LoRaWAN primarily operates on an unregulated spectrum and doesn't need any license to use as long as you follow the frequency restrictions in your region.

Our devices are readily available in AS923, EU868, US915 and AU915 configurations. We also offer custom frequencies on request. Please feel free to contact our client growth team for more information.

You can check our downlink decoders for the exact format to change sampling freqncy. In general it will be in hexadecimal 1001XXXX. Replace the XXXX with the hexadecimal value of minutes. For eg: To use a sampling interval of 45mins the downlink message will be 1001002D

Yes, while ellenex offers serverless micro-service platfrom as an option, you can integrate our sensors to any network or platfrom through the standard protocols. ellenex is partnered with global software partners to pre-configure devices to these platforms to provide ultimate flexibility and extendability for the customers.

If you are using ellenex platform, you will receive the product pre-configured to the platform. You just have to transfer the device to your account by following a few instructions mentioned in the device package. If you want to connect the device to your platform, we will share the instructions and payload format.
