Arduino Energy Meter Pulse Counter

Number of pulses used to measure energy.

Arduino energy meter pulse counter.

I know about pulse output from the analog energy meter as described here. I have digital energy meter which commonly used nowadays and arduino uno board. Now that you have this knowledge you can actually take measurements of everything. Calculating power 3600 seconds per hour 3600j per pulse i e.

So i can give that pulses to arduino uno board for counting and monitoring the pulses. Used to measure power. The gas meter has a reflective patch on the first dial and the water meter has a rotating silver notch which comes in handy when reading with an optical sensor. I have done this task.

1000 pulses kwh 1 pulse per wh void setup serial begin. Example arduino sketch for interrupt based pulse counting. Power and energy double power elapsedkwh. The connectivity is like this.

Long pulsecount 0. For example in the same way i read my gas and water consumption. Int ppwh 1. Number of pulses per wh found or set on the meter.

I want to take a pulse output digital pulses from this digital energy meter. Interrupt based pulse counter. 1 wh 3600j therefore instantaneous power p 3600 t where t is the time between the falling edge of each pulse. Arduino 5v meter input terminal switch inside meter meter output terminal arduino digital pin the basic model is that you supply 5v between 5 30 volts according to the manual and every time the meter measures 1kw it completes the circuit and you can measure 5v on the relevant pin on the arduino.

Extending the arduino energy sensor. Calculating energy for the a100c meter each pulse represents 1 1000th of a kwh i e.
