EXPANDED TECHNICAL DETAILS
Industrial PIC-Based Agricultural Hub
This project demonstrates the use of a PIC Microcontroller (e.g., PIC16F877A) to manage a high-density environmental sensing network for a greenhouse.
- MPLAB Code Configurator (MCC) Integration: Leverages professional-grade development tools to manage ADC sampling and PWM generation. The PIC monitors capacitive soil moisture, analog light levels, and DHT11 air quality.
- Autonomous Climate Correction: If the PIC detects low humidity, it activates a high-pressure water pump/mister via a relay; if the temperature is too high, it triggers a ventilation fan.
Reliability
- Hardware Watchdog Logic: Includes a dedicated hardware timer to automatically reset the microcontroller in the event of a code hang, ensuring 24/7 reliability for sensitive plant life.
