It's crucial to be aware of other products named YL-105 to avoid ordering the wrong item:
Use the digital output to trigger a relay for a humidifier or dehumidifier.
int sensorPin = 2; volatile int pulseCount = 0; yl-105 datasheet
The YL-105 is not a bare Hall effect IC; it is a . It typically features a 49E (or equivalent) linear Hall sensor, a comparator circuit (often an LM393), a potentiometer for adjustable sensitivity, and onboard power regulation. The module outputs a clean digital signal (HIGH/LOW) based on the presence of a magnetic field, making it directly compatible with 3.3V and 5V microcontrollers like Arduino, Raspberry Pi, and ESP32.
The is a critical hardware accessory designed specifically for the popular nRF24L01+ 2.4GHz RF transceiver module . It solves the most common issues engineers and makers face when working with the transceiver: power supply instability and strict voltage constraints. It's crucial to be aware of other products
