Send Inquiry


With this small Hall magnetic field sensor you can detect magnetic fields, using the sensor's digital output and the integrated status LED. This transistor interconnects if the module is positioned in a magnetic field. This can be read out at the signal output as a voltage value, the sensor signal output switches to low state. With individualized codes, the sensor will able to be used on other devices. This sensor can either be solidly soldered or be used on a breadboard.
