ESP8266 IoT Energy Monitor
This project creates a realpower energy monitor using a NodeMCU module with ESP826612 and ADS1115. Wiring up the circuit. This basic version is for apparent power only. To keep component count low and the circuit as simple as possible the ADS1115 is used in differential mode eliminating the need for bias resistors. The hard part is getting a licensed electrician to wire up the clamp on ...
