#194 IKEA Saltviken Scale Hack: Create a 150kg Scale Connected to Google Firebase

14YmiEycup4/default.jpg

Today we will hack an IKEA SALTVIKEN bathroom scale and create a connected weight sensor for up to 150 kg. We will use Googles free No- SQL Firebase cloud service as a data storage. To do that, we have to tear this nice scale apart and have a look inside.
We will:
- Re-use the load cells of the IKEA scale to measure heavy loads up to 150 kg or another scale, maybe even old an defective one
- Replace the original PCB with an HX711 and an ESP32
- Learn from IKEA how to wire the four special load cells that they add the weight
- Transfer data to the new No-SQL database “Firebase” provided by Google
- Calibrate the scale
