Water Level Controller with Real time Data Logger and Bluetooth

Updated: Jan 2

Learn here to create Arduino Based Water Level controller with RTC data logger. We’ll use the HC SR04 ultrasonic to measure tank level, the real time clock (RTC) module to take time stamps and the SD card module to save the water storage in liter, water filled in percentage and Pump motor ON/OFF status on the SD card, and Bluetooth send water level data to android application for HTML Java script Tank Gauge display.
