Monitor the counter of an electricity meter with Arduino and infrared light sensor.

Electricity meter with infrared light barrier

The software consists of two parts:

  • Data acquisition part running on an Arduino Nano. It controls the infrared light barrier, detects trigger levels and communicates with a master computer over USB serial.
  • Data recording part running on a the master computer (Raspberry Pi). It retrieves the data from the Arduino over USB serial and stores counter and consumption values into a round robin database.

There is a blog in german language that explains use case and function: Infrarot Lichtschranke mit Arduino zum Auslesen des Stromzählers.

Commands from host (RasPi) to Arduino

  • D - retrieve and print raw data
  • T - enter trigger mode and print trigger data (0/1)
  • S low high - Set trigger levels (e.g. 85 90)
  • C - Cancel data acquisition and enter command mode

Arduino is in trigger mode upon start - Send C to enter command mode
