Monofasic two-wire electronic meter DSS666 CHINT
Longtime I have this meter and I decided to use it to integrate either with Arduino or ESP8266 and record data in the Emoncms platform (OpenEnergyMonitor).
Measurement mode Single Phase Phase-Neutral
Pulse Output Terminals
Some meters have a pulse output associated with the electrical consumption, in the case of this specific meter, each time the front led diode is turned on, it sends a pulse that activates an optocoupler for the output of terminal pulses (11 +) ( 12 -)
Relationship 3200imp / Kwh
Relationship: this meter is 3200imp “impulses” / kwh, the integrated meter performs the measurement and integration of kilowatts / hour and sends pulses according to consumption.
with the help of a microcontroller “Arduino, ESP8266 or ESP32” in next tutorials we will measure the Watts consumed.
