I started researching bed occupancy sensors and came across a great post from Zack at Self Hosted Home where he used an ESP8266, 4 load cells and a HX711 to build what is essentially a bed size weight scale to determine if someone was in bed or not. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning you can send simple text commands to control the device. Load cells with bigger range while having a higher maximum weight have a less accurate weight. Using the HX711 load cell amplifier with an ESP8266 seems to cause some issues. Silicon Labs As we already have all sorts of home automation in place anyway the idea was born to integrate en ESP8266 into two of those cheap scales and – while ripping out most of their electronics – base the new scale functionality on the load cells already in the cheap scale. As mentioned before, the excitation voltage applied to the load cell is 5. dk // Load cells are linear.
