This month we allowed the ESP to acquire weight data and fixed the issue with weight calibration. We did this by giving the weight sensors the capability to self-calibrate after two button presses. We have now connected the ESP to an API and made it so the ESP will enter sleep mode to conserve power. This is because we will send data to the database through the API every few hours instead of constantly. For weatherproofing, as the objects are required to be durable due to the fact that they will be exposed to the element, we finished weatherproofing the frame and designing a weatherproof case for the solar panel which acts as our ESP’s power source.
