KS0492 Keyestudio Micro bit Honeycomb Hall Magnetic Sensor (Black and Eco-friendly)
Description
The Keyestudio micro bit honeycomb hall magnetic sensor is fully compatible with micro bit control board. In the experiment, we connect it with the micro: bit by a crocodile clip. There are 6 sockets on it, 2 G, 2 V and 2 S are connected. Additionally, G is GND, VV is VCC, and S is the signal end of the module.
During the test, we test the analog value of S end via micro: bit control board. The analog value read is decreasing fast when the nearby magnetic field is detected.

Test Result
Wire according to connection diagram, upload the code successfully, open the serial monitor software(like Arduino IDE), set baud rate to 115200. The analog value of S end is shown on the monitor. The analog value is decreasing fast and LED of the sensor is on when the magnetic field tested is nearby. LED dot matrix of micro：bit shows the pattern图；otherwise，LED is off，LED dot matrix shows the pattern图. As shown below:
