        abstract = {This study introduces a compact and economical IoT-based Hygiene Monitoring System aimed at the assessment of hygiene-related spaces such as public toilets, hospitals' auxiliary rooms, hostels, and waste management facilities. Traditional hygiene monitoring is often done manually and periodically, which might result in delayed cleaning activities. The IoT system uses an ESP32 microcontroller along with a MQ-135 gas sensor for detecting ammonia (NH3), bad odor gases, and air quality deterioration, as well as the DHT11 sensor for measuring ambient temperature and humidity levels. The sensor readings are sent via Wi-Fi to the Blynk app, allowing users to monitor the hygiene status remotely in real time. Based on thresholds, the system determines whether the observed space is in a safe, moderate, or poor hygiene state.},
