Arduino Water Meter Pulse

It emits an infrared light and detects the reflection.

Arduino water meter pulse. Reading pulses from meters with pulse outputs. 1 whr 3600j therefore instantaneous power p 3600 t where t is the time between the falling edge of each pulse. Flow sensor is powered with an external 9 volt battery. When the arduino detects the pulse it immediately triggers the pulse counter function.

The code uses an external interrupt on the arduino s digital pin 2. Uploading code to arduino and measuring. I bought it in 6 dollars. Use the tcrt5000 ir barrier line track sensor.

Water flow sensor for flow rate volume measurement using arduino code along with. Upload the water flow meter code to the arduino. Calculating power 3600 seconds per hour 3600j per pulse ie. Digital pin 3 of arduino is configured as interrupt pin.

This function then counts the total. This is used to read the pulses coming from the flow meter. 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. When the arduino detects the pulse it immediately triggers the pulsecounter function.

In some cases newer water meters are equipped with a pulse output. Uploading the flow meter code to the arduino and measuring water flow rate. I will explain about it during code explanation. For the a100c meter each pulse represents a 1000th of a kwhr of 1whr of energy passing through the meter.

Upload the flow meter code to your arduino. The code uses an external interrupt on the arduino s digital pin 2. This is used to read the pulses coming from the flow meter.
