Ultrasonic Long Range Module GY-US42

GY-US42 is a high-quality ranging sensor module with low power consumption, small size, and easy installation. Its working principle is that after the probe emits ultrasonic waves and irradiates the object to be measured, the probe receives the returned sound waves and uses the time difference to calculate the actual distance.
The module has 3 ways to read data, namely the serial port UART (TTL level), IIC, pulse PWM mode, the baud rate of the serial port is 9600bps and 115200bps, configurable, there are continuous, query output two ways, can be saved after power off Setting; IIC can modify the internal address, which is convenient for one IIC bus to connect multiple modules at the same time; pulse PWM output is the same as SR04. The module can adapt to different working environments, and directly connect with the single chip microcomputer. Can be widely used in intelligent robots, teaching laboratory instruments, production
On-line product inspection, quadcopter, anthropometry, smart car and other occasions.
Note: Because of the use of integrated ultrasonic probes for receiving and sending, the range of the blind zone of the distance measurement is about 20cm, and the distance measurement within 20cm is invalid.
