NB-IoT
Wireless illuminance logger
Wireless illuminance logger is a lux meter, measuring the intensity of light as visible by the human eye. The precision spectral response and strong IR rejection of the device enables it to accurately meter the intensity of light as seen by the human eye regardless of light source.
Efento NB-IoT loggers transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT sensors can be integrated with any cloud platform.
You can use a free mobile application to configure the device and read the data from its memory.
- Measurements: 0.01 lux to 83 000 lux
- Measurement period: 1 minute – 10 days (configurable by the user)
- The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
- Battery ensures up to 5 years of maintenance-free operation
- Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
Key features
Efento Cloud
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.Calibration certificate
At the customer’s request, each Efento sensor can be supplied with a calibration certificate in accordance with ISO / IEC 17025. The test is performed in an external, ILAC certified laboratory.Data security
Data transmitted wirelessly can be encrypted. Thanks to that, unauthorized persons cannot hijack the communication between sensors and other devices. Efento sensors' software can be updated over the air, which will allow you to easily install any security patch that is released.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.
