This Long Range Ultrasonic Distance Sensor was actually designed to be used with the APM Flight Controller Module to be used in Drones - RC Quadcopter and Planes but can also be used as a general purpose distance sensor with the Arduino or the Raspberry Pi. You can use this sensor with the APM Flight controller to help your drone with Automatic Takeoff, Landing, Terrain Following, Obstacle Avoidance, etc. If you plan to use this sensor as a distance sensor with the Arduino, Raspberry Pi, or any other general purpose micro controller, it offers many different interfaces - Serial TTL, PWM, I2C, etc. You can use any one of these interfaces to use this module!

Electrical Specifications

  • GY-US42 is a low cost, high quality distance range sensor module
  • Working voltage 3-5v, small power consumption, small size, easy installation
  • IIC Interface can modify the internal address, to facilitate an IIC bus at the same time to access multiple modules using the same I2C Lines
  • Pulse PWM output, same as SR04.
  • The module can be adapted to a different working environment and connected directly to the microcontroller
  • You may use the serial interface to connect the sensor to the computer using a USB to Serial Interface
  • IIC mode can be directly connected with APM, Pixhawk, and other flight control.
  • Provide arduino, 51, stm32 microcontroller communication procedures, does not provide schematic and internal microcontroller source.
  • As a result of the use of transceiver integrated ultrasonic probe, ranging from the blind area is about 20cm. Within 20cm range is invalid.
