Flash'O is a LoRaWAN class A sensor. It is a meter radio interface that transmits the cumulated flash LED values from any pulse meters: water, gas, electricity, energy. The sensor is connected to an optical probe that recovers light pulses.

The Flash'O sensor is powered by a disposable 3.6V A-type battery. It incorporates one digital input, and also includes an internal antenna.

The level or a counter can be transferred to the input. It is also possible to get the voltage of the power supply.
