The flow meter sensor outputs pulse of a variable frequency that is proportional to the rate of fluid flowing through the pipe. The number of litres flowing through the sensor can be calculated by ...

By using a flow sensor with a microcontroller like Arduino, we can calculate the flow rate, and check the volume of liquid that has passed through a pipe, and control it as required.

Circuit diagram of the water flow meter is shown in Fig. 1. The circuit is built around Arduino Uno board (Board1), 16×2 LCD (LCD1), and water flow sensor YF-S201 (SENSOR1).

The software constists of two components. First, an Arduino sketch to process the raw sensor values and to detect a revolution of the ferraris disc, and second a daemon which receives the energy ...

We have designed an IoT based water flow meter. It is powered by the ESP32-S3 SoC from Espressif. We have used an ESP32-S3 Wroom 1 module for the project which will be much easier to handle when ...

Neil Hannay explains how to understand flow meter sensor and pulse output types for efficient system operation FLOW meters have developed into many forms over the years, from mechanical devices – such ...
