Vega SI-21 - pulse counter with external antenna

The Vega SI-21 pulse counter is designed for counting the pulses arriving at 4 independent inputs, with subsequent accumulation and transfer of this information to the LoRaWAN® network. The Vega SI-21 has an external LoRaWAN® antenna and a degree of enclosure protection IP67. It is also possible to connect an external temperature sensor to remove the temperature readings. The pulse counter can be used for any utilities’ meters and industrial equipment with pulse output like a herkon or an open-drain output. Also, Vega SI-21 can be used as a security sensor or a temperature sensor.
