GY-53 是一款低成本数字红外测距传感器模块。
工作电压 3-5v，功耗小，体积小，安装方便。
其工作原理是，红外 LED 发光，照射到被测
物体后，返回光经过 MCU 接收，MCU 计算出
时间差，得到距离。直接输出距离值。
此模块，有两种方式读取数据，即
串口 UART（TTL 电平）+PWM（1 线）
或者芯片 IIC 模式，串口的波特率有9600bps 与
115200bps，可配置，有连续，询问输出两种方式，
可掉电保存设置。提供 arduino，51，stm32 单片机
通讯程序。，不提供原理图及内部单片机源码。
模块另外可以设置单独传感器芯片工作模式，
作为简单传感器模块，MCU 不参与数据处理工作。(GY-53 is a low cost digital infrared range sensor module.
Working voltage 3-5v, small power consumption, small volume, easy to install.
The principle of the work is that the infrared LED is illuminated and irradiated to be measured.
After the object, the return light is received by the MCU, and the MCU is calculated.
Time difference, get the distance. Direct output distance value.
This module, there are two ways to read the data, that is,
Serial UART (TTL level) +PWM (1 line)
Or chip IIC mode, the baud rate of the serial port has 9600bps and
115200bps, configurable, continuous, two ways of asking output,
Power saving settings. Provide Arduino, 51, STM32 Singlechip
Communication program. Do not provide the principle diagram and internal single chip source code.
The module can also set up the working mode of the individual sensor chip.
As a simple sensor module, MCU does not participate in data processing.)
