over time when exposed to moisture and electric current. To extend life, it is recommended to power the sensor only during readings rather than continuously. Applications Automated Irrigation:
Ensures the NRF24L01+ receives a stable and reliable 3.3V power supply, which is critical for reducing signal noise and ensuring reliable wireless communication.
The YL-105 adapter features two sides: the female header side (for the NRF24L01 module) and the pin header side (for the microcontroller). Pin Configuration (Microcontroller Side) Ground (0V) VCC: CE: Chip Enable CSN: Chip Select Not SCK: Serial Clock MOSI: Master Out Slave In MISO: Master In Slave Out IRQ: Interrupt Request 4. Typical Applications
| Problem | Likely Cause | Solution | |---------|--------------|----------| | Output always LOW | Threshold too low or magnet always present | Turn potentiometer clockwise to increase threshold | | Output always HIGH | Threshold too high or no power | Turn potentiometer counterclockwise, check VCC/GND | | Jittery output near switching point | No hysteresis | Add a 100k resistor from DO to non-inverting input, or use software debounce | | No response even with strong magnet | Wrong magnetic pole | Use south pole of magnet | | AO reads constant voltage | Hall sensor damaged or VCC unstable | Check VCC with oscilloscope; replace module if needed |
The YL-105 uses a resistive sensing element. These sensors utilize a film-like material whose resistance changes based on the humidity in the air.
Detects when soil is too dry (needing water) or sufficiently wet, allowing for the automation of irrigation systems. 2. Technical Specifications (YL-105 Datasheet)
