Arduino Energy Meter Pulse Counter

For example in the same way i read my gas and water consumption.

Arduino energy meter pulse counter.

Long pulsecount 0. 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. The connectivity is like this.

Contest my 12 input high precision pulse counter kwh x2f. Used to measure power. Number of pulses used to measure energy. I want to take a pulse output digital pulses from this digital energy meter.

Interrupt based pulse counter. W hello guys i want to do a system for my home where i can monitor energy either from energy meter pulse output sdm72dr or using current transformer arduino sensor and displaying the cost of kwh used in a serial monitor which one would be reliable and provide accurate information i had about 17000 rs last months bill due. Calculating energy for the a100c meter each pulse represents 1 1000th of a kwh i e. So i can give that pulses to arduino uno board for counting and monitoring the pulses.

I know about pulse output from the analog energy meter as described here. Number of pulses per wh found or set on the meter. 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.

Int ppwh 1. Power and energy double power elapsedkwh. Calculating power 3600 seconds per hour 3600j per pulse i e. 1 wh of energy passing through the meter.

1000 pulses kwh 1 pulse per wh void setup serial begin. 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.
