Smart eNose Food Waste Management System

· The MQ4 sensor detects the CH 4 gas while the MQ135 sensor detects CO 2 and NH 3 in this system. We use a 5 kg strain gauge load cell sensor and HX711 A/D converter as a weight sensor to measure the weight of food being wasted. To ensure the accuracy and efficiency of our system, we first calibrate our sensors as per recommendations to run in the environment with the flow. We collect our …
