Wireless AC Voltage Level Sensor
The Wireless AC Voltage Level Sensor from Fidar Electronics measures mains RMS voltage from 50 to 250 V and records every sag and surge. It links over a LoRa radio with no cabling at all.
Measures AC voltage from 50 to 250 V
Sag and surge alarm thresholds
Continuous voltage trend for power-quality review
LoRa radio link up to 1 km line of sight
AES-128 encrypted payloads
Pairs with the FWL1600-01 LoRa card
No cabling; pairing takes seconds
Low-battery warning per node
An AC voltage level sensor measures mains RMS voltage from 50 to 250 V. Supply quality dictates equipment life: a sag raises motor current and cooks the windings, a surge kills power supplies and electronics. A continuous voltage record is both the evidence behind a damage claim and the trigger that fires before the damage — and it documents outage count and duration along the way.
