The sensor is equipped with an external, temperature and humidity probe with a length of 1m, allowing measurements in places where the sensor cannot be placed directly.
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.
