Wireless temperature and humidity loggers are used to measure both temperature and humidity in places which require constant monitoring of the prevailing conditions – museums, archives or churches to monitor atmospheric conditions affecting exhibits.
Efento NB-IoT sensors 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.
- Temperature: -15 to +70°C, accuracy: up to 0.4°C
- Humidity: 0 to 99% RH, accuracy up to 4% in the range of 0 to 80%
- Battery ensures up to 5 years of maintenance-free operation
- 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
- The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
- Sensor's configuration can be changed remotely from the cloud or with a mobile application over Bluetooth Low Energy
