This module can be powered by Typec interface ,5V, just connect to a power bank. Or connect to external power supply through the positive and negative poles of the 2.54 through-hole, the voltage range is 3.3 to 40V
Function:
1. Determine N, S polarity
2. Detect magnetic field strength: 1.6mV/GS (AOC)
How to use:
1. After powering on, you can use ADC to collect AOC voltage to determine the polarity of the magnet. The reference voltage is 1.65V
2. After powering on, press the power button, and after 30 seconds, vertically approach the magnet to determine; the polarity LED light will light up to remind you, and the polarity corresponding to the pin header end is high level, otherwise it is low level;
Note: After turning on the switch, you need to stay away from the magnet during the self-test of the product;
Module Description:
1.This module can be powered by the Typec interface ,5V, just connect to a power bank. Or connect to an external power supply through the positive and negative poles of the 2.54 through-hole, the voltage range is 3.3 to 40V.
2. The working principle of the linear Hall module is: its input is the magnetic induction intensity, and the output is a voltage proportional to the input. Theoretically, the static output voltage (B=0GS without magnetic field) is half of the power supply voltage. For example: when the input voltage is ,5.0V (a 3.3V LDO is added to the product, and the sensor and MCU power supply are provided by LDO, if there is no magnet close, the A0C output pin voltage is: 3.3V/2=about 1.65V.
3. When the S pole magnetic field is close to the Hall print surface, the output voltage will increase linearly with the increase of magnetic field strength, and the blue LED light will be on; on the contrary, when the N pole magnetic pole is close to the Hall print surface, the output voltage will decrease linearly with the increase of magnetic field strength, and the red LED light will be on.
4. The circuit integrated in this module has low noise output, which makes it unnecessary to use too much external filtering. It also includes precision resistors, which provide more temperature stability and accuracy for circuit design.
Note:
1.Please allow 1-3cm differs due to manual measurement.
2.Due to the different monitor and light effect, the actual color may be a slightly different from the picture color.
