Linear Hall magnetic module and digital 13 interface have their own LED to build a simple circuit to make magnetic field.
The prompt light uses the LED of the digital 13 interface to connect the linear Hall magnetic sensor to the digital;
3 interface, when the linear Hall magnetic sensor senses a key signal, the LED lights up, otherwise,
put out
Product features
1, with signal output instructions
2, with mounting holes, convenient for fixed installation.
3. The output effective signal is low.
4. Adjustable sensitivity (fine adjustment)
5, the magnetic field induction detection sensitivity is extremely high.
6. The circuit board outputs the switching value, which can be directly connected to the I0 port of the single chip microcomputer.
7, can be used for motor speed measurement, position detection and other occasions
