Interface

Pin No. Symbol Descriptions
1 DOUT Digital output
2 AOUT Analog output
3 GND Ground
4 VCC Positive power supply (3.3V-5.0V)

How to use

We will illustrate the usage of the module with a NUCLEO-F103RB (STM32F103) or Arduino UNO development board. 1. Download the Demo code and extract it, then program the examples to your NUCLEO or Arduino development board. 2. Connect the development board to a PC via a serial wire and the module to the development board. Then, power up the development board and start the serial debugging software (e.g. PuTTY or Serial Monitor). Here is the configuration of the connection between the module and the development board.

Port NUCLEO-F103RB Pin
DOUT A1
AOUT A0
GND GND
VCC 3.3V
Port Arduino Pin
DOUT D2
AOUT A0
GND GND
VCC 5V

Here is the configuration of the serial port.

Baud rate 9600
Data bits 8
Stop bit 1
Parity bit None

Expected result

  • When a barrier is placed near the sensor, the signal indicator will turn on or else turn off.
  • The serial output will change according to the distance between the module and the barrier.
