Wireless DC Current Sensor
The Wireless DC Current Sensor from Fidar Electronics measures direct current in a circuit across a 0 to 5 A range. It links over a LoRa radio with no cabling at all.
0–5 A DC measuring range
Suited to solar arrays and battery banks
Fast response to current drops and surges
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
A DC current sensor measures direct current in a circuit across a 0–5 A range. In solar arrays, battery banks and DC equipment, current is the clearest health signal there is: a drop in charge current, an abnormal draw or a leakage path all appear in the trend long before something fails. Logging that trend gives you both the early warning and the evidence for the post-mortem.
