Hello friends, I hope you all are doing great. Today, I am going to share the IoT Smart Energy Meter with ESP32 - Proteus Simulation , the seventh project of our IoT Projects series. If you have searched for a Proteus simulation of an energy meter or a smart plug with an ESP32, here is a complete one. An ESP32 measures two 12 V loads with INA219 current sensors, switches them with relays, adds up the energy they use, works out what it costs, trips a load that draws too much, and shows everything on an LCD and on a live web dashboard for your laptop and your phone. Smart plugs and energy monitors are among the most useful IoT devices: they tell you what each appliance really uses and let you switch it from anywhere. In this tutorial, we will go through the circuit, learn how an INA219 measu ...
