Real-time Gas Monitoring. The meter from the gas company has on the last digit a small reflecting part of 3 by 3 millimeter. This reflecting surface is located in the middle of the digit six, so every time the digit six comes around we have used 0.010 m³ Gas. I used a CNY70 light reflecting sensor to measure every time the six comes around. The CNY70 is connected to the RFXmeter from RFXCOM who collects all the counts. Once every 30 seconds the data is send wireless to my Home Automation system.
