In response to declining air quality caused by environmental pollution and climate change—particularly the dry conditions created by air conditioner use—a talented student from Long Tri A Secondary School has developed an innovative automatic mist humidifier. This groundbreaking project maintains optimal humidity levels, reduces temperature, protects health, and conserves energy while addressing the limitations of traditional humidification methods in agriculture, especially within greenhouse environments.
HOW DOES IT WORK
The automatic mist humidifier system combines advanced components to efficiently monitor and regulate environmental conditions through four key processes:
Data Collection
DHT11/DHT22 sensors continuously measure temperature and humidity, transmitting real-time data to the control unit for immediate analysis.
Signal Processing
The central control circuit (Arduino/ESP32) analyzes sensor data and compares it against pre-configured thresholds to determine necessary adjustments.
Automated Adjustment
When humidity drops below the set threshold, the system activates the ultrasonic mist humidifier to increase moisture levels. If temperature exceeds the allowed limit, the TEC-12706 Peltier cooler activates to cool the air. Once desired levels are achieved, the system automatically shuts off to conserve energy and water.
Continuous Operation
This process repeats continuously, ensuring a stable and optimal environment at all times.
The system shows excellent potential for future enhancements, including integration with mobile applications for remote monitoring and adjustment, as well as incorporating self-learning algorithms to optimize operating parameters over time.
