GY-US42 i2C Pixhawk APM Distance Measurement Ultrasonic Sensor Control Module
US42 is a low cost high quality range sensor module.
Working voltage 3-5 V, small energy consumption, small size, easy installation.
Its principle of work is that the probe emits ultrasonic waves, irradiated to the measured object, the probe receives the return waves, the use of the time difference, calculate the real distance. There are three ways to read the module data, ie serial UART (TTL level), PWM mode, CII,
Baud series SERIES 9600bps and 115200bps, can be configured, there is continuous, request the output in two ways, you can save the power settings.
The IIC can modify the internal address, to facilitate an IIC bus at the same time access to multiple modules. Pulse PWM output, same as SR04.
The module can adapt to a different work environment and connect directly to the microcontroller.
When the computer needs USB to TTL module, direct connection.
The IIC mode can be connected directly with APM, Pixhawk and other flight control.
Provide arduino, 51, microcontroller stm32 communication procedures, does not provide a schematic and internal microcontroller source.
As a result of using the integrated ultrasonic probe of the transceiver, the blind zone is about 20 cm. Within 20 cm the range is invalid.
