The climate issue is the biggest challenge of our time and food waste can be considered an unnecessarily large environmental burden. Reducing food waste and increasing resource management in the food chain is a priority area in a sustainable society, therefore technology development must be used in advantage to achieve long-term environmental and sustainability goals. In this work, we have developed a hardware / software integrated wireless sensor network to get information as early as possible about food going bad. The developed wireless sensor network is built using Raspberry Pi, ESP-WROOM-32 microcontroller with integrated communication modules and gas-sensitive sensors. The remote control for data collection and other tasks is performed wirelessly from a laptop and has been programmed in Phyton. Experiments have been carried out with promising results.
