Purpose
This Mapua University study set out to monitor raw chicken freshness in storage by tracking temperature, ammonia, and hydrogen sulfide levels inside a crate, and to evaluate the accuracy and effectiveness of the device.
Description
The crate is built around an Arduino that reads MQ-136 and MQ-137 gas sensors for hydrogen sulfide and ammonia, a DHT22 for temperature and humidity, and an ADS1115 ADC for precise sensor conversion. Readings are shown on an onboard LCD and streamed to ThingSpeak for remote monitoring, with gas concentrations converted to PPM through calibrated formulas. The system assesses freshness under different temperature conditions, supporting food safety in poultry storage and transport.
