GY-US42 is a low-cost high-quality range sensor module, operating voltage 3-5v, low power consumption, small size, easy installation.
Its working principle is that the probe emits ultrasonic waves, irradiated to the measured object, the probe receives the return sound waves, the use of time difference, calculate the actual distance. There are three ways to read the data module, that is, serial port UART (TTL level), IIC, pulse PWM mode, the serial port baud rate of 9600bps and 115200bps, configurable, continuous, query output in two ways, Set up.
IIC can modify the internal address, to facilitate an IIC bus at the same time access multiple modules. Pulse PWM output, same as SR04. The module can be adapted to a different working environment and connected directly to the microcontroller. When the computer needs USB to TTL module, direct connection.
IIC mode can be directly connected with APM, Pixhawk, and other flight control. As a result of the use of transceiver integrated ultrasonic probe, ranging from the blind area is about 20cm. Within 20cm range is invalid.
Measuring range: 20cm-720cm (Vcc = 5v).
