Hall switch sensor module magnetic field detection STEAM education hardware artificial intelligence kit

This sensor uses the 3144 Hall switch integrated circuit, which is a magnetic sensitive circuit with the characteristics of small size, high sensitivity and fast response.
Integrated power indicator light and working status indicator light can clearly check the working status of the sensor. When the sensor senses a magnetic field, the signal output bit outputs a low level and lights up the indicator light; when there is no magnetic field, the signal output bit outputs a high level.
