Special Features

  • Overview ：The module has three ways to read data, namely serial UART, IIC and PWM. The baud rate of the serial port is 9600bps and 115200bps, which can be configured. There are two ways: continuous and query output. The settings can be saved after power failure; The IIC can modify the internal address, so that one IIC bus can connect multiple modules at the same time; Pulse PWM output, the same as SR04. The module can adapt to different environments and directly connect with the microcontroller.
  • Features: GY-US42 has a power supply of 3-5 v and a built-in MCU to calculate the distance. GY-US42 has three communication formats: IIC, serial port and PWM. The short distance measurement cycle is 40 HZ, and it is also equipped with corresponding upper computer software. GY-US42 has integrated probe and small volume.
  • IIC mode (default) : After the module receives the start measurement command, the INT pin will be pulled up internally at this time, and the measurement will be started about 12ms later, and the ultrasonic wave will be sent. When the measurement result is available, the INT pin will be pulled down internally, and the distance data can be read. If the IIC mode does not use the INT pin, a certain delay will be taken after sending the start measurement command. Then send the read data instruction.
  • Pulse PWM mode: the module is powered on. The host sends a pulse of about 20us to the CR pin of the module. After about 12ms, the module starts measuring, and the DT pin is pulled up. The host can start timing at this time, and the host finishes timing when the DT pin is pulled down. Finally, the distance is calculated according to the formula. The user can perform corresponding compensation calculation by himself.
  • Serial port mode operation steps: First use USB to TTL module or single chip microcomputer and GY-US42 module to connect TX-- RX,RX----TX, connection mode is cross connection. Then GY-US42 module default is automatic output, TX pin sends data, directly in the serial port can obtain data, format reference to the above communication protocol. If other operations are required, corresponding instructions can be sent.

Description

Description: GY-US42 is a low-cost and high-quality range sensor module. The working voltage is 3-5v, the power consumption is small, the volume is small, and the installation is convenient. Its working principle is that the probe emits ultrasonic wave, irradiates the measured object, the probe receives the returned acoustic wave, and uses the time difference to calculate the actual distance. The module has three ways to read data, namely Serial UART (TTL level), IIC, pulse PWM mode. The baud rate of the serial port is 9600bps and 115200bps, which can be configured. There are two modes: continuous and inquiry output. The settings can be saved after power failure. IIC can modify the internal address, so that one IIC bus can connect multiple modules at the same time. Pulse PWM output, the same as SR04. The module can adapt to different working environments and directly connect with the microcontroller. When connecting the computer, you need a USB to TTL module for direct connection. IIC mode can be directly connected with APM, Pixhawk, etc. The communication program of arduino, 51, stm32 single chip microcomputer is provided, but the schematic diagram and internal single chip microcomputer source code are not provided. Because of the use of an integrated transmitter receiver ultrasonic probe, the range of blind area for ranging is about 20cm. Measuring distance within 20cm is invalid.
