Joy-IT SEN-KY035BM KY-035 Bihor Analog Hall Sensor
Joy-IT SEN-KY035BM, a KY-035 Bihor analog magnetic-field sensor module built around an AH49E Hall-effect sensor.
Pinout
- VCC
Module supply. Use 3.3 V with ESP32 ADC inputs; many modules also tolerate 5 V when used with 5 V MCUs.
Type · PowerVoltage · 3.3V - GND
Ground reference shared with the controller.
Type · Ground - S
Analog signal output to an ADC-capable GPIO. Calibrate the no-magnet baseline and threshold during homing.
