Single Phase Smart Power Meter (PEM-1000)
WiFi
LoRa
Features
PEM-1000 can measrue AC (1) Voltage: 80 ~ 260V AC, (2) Current: 0 ~ 100A, (3) Power: 0 ~ 22KW, (4) Electrical Energy: 0 ~ 9999KWh.
PEM-1000 can transmit the measured values using (1) MQTT/WiFi, (2) WiFi and (3) LoRa techniques. Methods (2) requires MQTT server and method (3) requires LoRa Gateway to relay the received messages to the MQTT Server. Messages processed in the MQTT Server can be displayed in the remote PC monitor.
