Interfacing Waterflow sensor with Bharat Pi
INTERFACING WATER FLOW SENSOR USING BHARATHPI Introduction of BHARATPI : A single board architecture with compute, network and storage designed to build any IoT idea into a product. The board comes with a ESP32 Wroom 4MB memory + WiFi + Bluetooth + SD card slot. You can program the board using Arduino IDE or microPython. All ESP programs are compatible with Bharat Pi boards. Introduction of Water Flow Sensor: The sensor comes with three wires: red (5-24VDC power), black (ground), and yellow (Hall effect pulse output). By counting the pulses from the output of the sensor, you can easily calculate the water flow rate. Each pulse is approximately 2.25 milliliters. Note this isn’t a precision sensor, and the pulse rate does vary a bit depending on the flow rate, fluid pressure, and sensor orientation. It will need careful calibration if better than 10% precision is required. This sensor sits in line with your water line and contains a pinw...
