Pulse Acquisition
PULSE915-LRW collects pulses and counts them, and the current accumulated index is
sent to the gateway through the LoRaWAN module according to the preset reporting period,
and finally uploaded to LoRaWAN server. The connection between active pulse (Hall) and
passive pulse (reed switch) is as follows.
