Iot Smart Energy Meter
This is an iot based smart energy meter that I made it can monitor power, current, watt hour and unit energy consumed by the device
You can see the working video here
Supplies
Nodemcu, acs712
Wiring
You can see the working of the project here
First of Al you have to make a extension board, and we need to connect Acs712 sensor to it so that we can measure current
First connect gnd, vcc of the sensor to nodemcu, then connect sensor output to the A0 of nodemcu
Detailed diagram will be provided
Coding
Upload code to nodemcu, you have to change three things in the code
1 blynk authentication key
2 WiFi ssid
3 WiFi password.
Change this three things and upload the code into nodemcu
1 blynk authentication key
2 WiFi ssid
3 WiFi password.
Change this three things and upload the code into nodemcu
Blynk App Setup
It is a very symbol process. First you have to download Blynk from play store
From the top right corner of it you can see a scanner
option click on it and scan the qr code given below
