Efento NB-IoT wireless hydrogen sulfide (H2S) logger measures gas concentration and transmit its values over a cellular network (Narrowband IoT). On top of the gas concentration,, the logger also measures temperature and humidity. Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT gas sensors can be integrated with any cloud platform.
Range: 0-100 ppm
Temperature: -35 to +70°C, accuracy: up to 0.4°C in the range from -20°C to +70°C and up to 0.5°C in the range -35 to -20°C
Humidity: 0 to 100% RH, accuracy 4% in the range of 0 to 80% and 7% in the range of 81 to 99%
Batteries ensure up to 10 years of maintenance free operation
The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
NB-IoT sensors send the data over the cellular network to Efento Cloud or any other cloud platform.
Measurement period: 1 minute – 10 days (configurable by the user)
User configurable alarm thresholds. If any of the thresholds is exceeded, sensor will send the data to the platform immediately
Sensor's configuration can be changed remotely from the cloud or with a mobile application over Bluetooth Low Energy
Together with Efento Cloud, the sensors enable constant monitoring, alerting about exceeding safe limits, generating reports and analyzes.
Long battery life
Loggers have been designed to work for up to 10 years on batteries. You do not have to remember about changing the batteries frequently or troublesome batteries charging.
Lower costs
Choosing wireless sensors and a cloud platform reduces the installation and maintenance costs.
Wide range of sensors
Efento sensors can measure various physical and chemical values. If you decide on one sensor today, you can expand your sensors fleet to another types anytime you want.
Integration
Standard communication protocols allow integration with any cloud platform or mobile application.
Easy set up
All you need to set up a logger is a smartphone with a free mobile application. The whole configuration takes no more than 15 minutes.
Gas sensors calibration
The gas sensors are pre-calibrated at the factory. If needed, user can independently calibrate the device using mobile application and a gas tank with a known gas concentration.
Edge analytics
Devices analyse the data and send it to cloud platform when needed. This allows to decrease the number of cellular transmissions and increase the battery lifetime. There are several types of analyses that can be performed by the sensor: from a simple comparison of the measured value to the threshold to more complex mathematical operations.
Software over the air update (SOTA)
The sensors are equipped with over the air software update mechanism, thanks to which, your fleet of sensors will always have the latest version of software. Moreover, SOTA is based on delta mechanism and only the difference between the current and the new version of the software is sent to the device. This saves both the battery and data transfer.
Full remote configuration
All the settings of the NB-IoT sensors can be changed remotely in a secure way. This allows you to easily reconfigure thousands of the deployed devices, no matter how far they are located.
Integration
We believe that the Internet of Things is about integrating data sources, analysing the data and drawing conclusions based on it. If you want to integrate Efento loggers with your software, cloud platform or mobile application, we will provide you with the necessary documentation, libraries, SDKs and we will gladly assist you.
Sensor’s passport
Sensor’s passport documents the entire lifecycle of a device. By accessing the data on Efento Cloud platform, the user can check all information about the sensor: date of sale, warranty status, date of calibration, information on all service activities. In addition, the user can download all documents regarding the device – a duplicate of calibration certificate or service protocols.
