Wireless open / close sensors

Wireless open / close sensors monitor the state of a machine, door or any other object that changes its state. Open / close sensors are used for instance to check whether the medical refrigerator is opened or if the warehouse door has been closed. Moreover these sensors can be also used as a general I/O sensors, which can detect the state of an alarm output of a device connected to it. Efento’s wireless open / close loggers use Bluetooth Low Energy, NB-IoT and LTE-M technologies to send the data to Efento Cloud or any other cloud platform.
