GY-53 is a low cost digital infrared ranging sensor module. Operating voltage 3-5v, low power consumption, small size, easy to install. The working principle is that the infrared LED emits light, and after the object is irradiated, the return light is received by the MCU, and the MCU calculates the time difference to obtain the distance. Directly output the distance value.

This module has two ways to read data, namely serial UART (TTL level) + PWM (1 line) or chip IIC mode. The baud rate of serial port is 9600bps and 115200bps, configurable, continuous, and query output. Mode, you can save the settings when power  is off. Provide arduino, 51, stm32 microcontroller communication program. , does not provide schematics and internal microcontroller source code. The module can also set the working mode of the individual sensor chip. As a simple sensor module, the MCU does not participate in data processing.
