GY-56 infrared laser ranging module

Description

The GY-56 is a low cost digital infrared range sensor module.
Operating voltage 3-5v, small power consumption, small size, easy installation.
Its working principle is that the infrared LED emits light and is irradiated
After the object, the return light is received by the MCU and the MCU calculates
The difference in time, get the distance. Directly output the distance value.
This module, there are two ways to read data, namely
Serial UART (TTL level) + IIC (2 line) mode,
The baud rate of the serial port is 9600bps and 115200bps, configurable,
There are continuous, inquiries output in two ways, you can power off the save settings.
Provide arduino, 51, stm32 microcontroller communication program.
GY-56 can set the upper and lower limit distance alarm value, switch output,
In the set interval, there is a block of the measured object and a high level is directly output.
Under the IIC mode, you can set different internal IIC addresses if necessary.
So that multiple sensors are connected on the same bus.
