Arduino Water Meter Pulse

This function then counts the total.

Arduino water meter pulse.

In this project we will interface yfs201 hall effect water flow sensor with arduino for measuring flow rate and volume of water or any other liquid this is a very wonderful project that can be used in industry or at home or at water flow measurement application in water tap tunnel river etc. In the above circuit i attached the pulse output pin of flow sensor to arduino digital pin 3. It emits an infrared light and detects the reflection. The code uses an external interrupt on the arduino s digital pin 2.

Digital pin 3 of arduino is configured as interrupt pin. I will explain about it during code explanation. However if you have an older power meter without a pulse output then you might be able to use one of the options below to sense your water consumption. Water flow meter which i used in the project is from aliexpress.

Flow sensor is powered with an external 9 volt battery. When the arduino detects the pulse it immediately triggers the pulse counter function. Use the tcrt5000 ir barrier line track sensor. Reading pulses from meters with pulse outputs.

Uploading the flow meter code to the arduino and measuring water flow rate. 1 whr 3600j therefore instantaneous power p 3600 t where t is the time between the falling edge of each pulse. Water flow sensor for flow rate volume measurement using arduino code along with. In some cases newer water meters are equipped with a pulse output.

When the arduino detects the pulse it immediately triggers the pulsecounter function. The code uses an external interrupt on the arduino s digital pin 2. Upload the water flow meter code to the arduino. I bought it in 6 dollars.

Calculating power 3600 seconds per hour 3600j per pulse ie. Uploading code to arduino and measuring. Upload the flow meter code to your arduino.
