IoT

To simplify the reading and evaluation of my electricity meter, I have built a reading head using an ESP32 board and a TRCT5000 infrared sensor. Unfortunately, I still have an old, so-called “Ferraries electricity meter”. But this one has a turntable with a red mark. This makes X revolutions per kWh, in my case 75. By the duration of a revolution the momentary consumption can be calculated then.

For the sensor, I then 3D printed a housing to mount it on the meter and align it. To fix the sensor, I used adhesive tape, which is normally used to mask walls when painting, in order to get sharp edges. This tape can be removed easily and still sticks sufficiently. I designed the case in Autodesk Fusion 360.
