Hardware Setup

WORKING

When the supply is on, the PZEM module starts monitoring the various electrical factors. The NODEMCU is programmed with deep sleep mode and recieves data from the PZEM after every sleep interval.This value is given to Google sheets which acts as the server that stores the sensor data. A google script code is written in the script editor of the sheet to write the sensor value to sheets. A code(also written in the same script editor) is used to send every new data written in sheets to Firebase database. The Firestore database of firebase is used to store the values, which is used as the backend of the Mobile Application.
