The chip hummed again.
Low resistance, allowing more current to pass, resulting in a low analog output value (near in Arduino). yl-105 datasheet
| Parameter | Value | |-----------|-------| | | 3.5V – 5.5V DC (typical 5V) | | Output Type | Digital (TTL logic) | | Output Logic | Active Low (output LOW when magnetic field detected) or Active High (configurable via onboard jumper) | | Sensitivity Adjustment | Yes – 10-turn potentiometer | | Comparator IC | LM393 (dual differential comparator) | | Hall Sensor | 49E (linear analog output) | | Detection Range | Up to ~15mm (depending on magnet strength) | | Response Time | < 2µs | | Operating Temperature | -40°C to +85°C | | PCB Dimensions | Approx. 32mm x 20mm | | Mounting Hole Diameter | 3mm |
: This indicates that the microcontroller cannot establish an SPI connection with the nRF24L01+ chip. Ensure that the module is firmly pressed into the YL-105's 8-pin socket, and double-check your SPI pins ( Pins 11, 12, 13 on the Arduino Uno). : Features an active AMS1117-3
The chip’s datasheet on his screen began rewriting itself in real time:
The YL-105 is used wherever an NRF24L01 module is required in a 5V environment: | Parameter | Value | |-----------|-------| | | 3
The YL-105 is popularly paired with Arduino for automated irrigation. Arduino Wiring -> Arduino GND -> Arduino GND AO -> Arduino A0
Place the sensor 5mm above a white surface. Turn the potentiometer until the onboard LED just turns off. Now, the module will trigger reliably when seeing white vs. black.
