Efento pulse counter is used to remotely monitor number of events which may be represented by pulses e.g. the number of elements coming off the production line, the number of doors opening/closing or number of people passing through the gate in a store. The sensor can simultaneously work with up to three water meters. Each counted pulse represents one unit, e.g. 1 door opening/closing, one impulse from a gas meter, one change of state of a connected device. Data is presented as the total number of pulse counted in the set time intervals.

Efento NB-IoT pulse counters transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Pulse counters are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT / LTE-M pulse counters can be integrated with any cloud platform.
