Introduction:
The Keyestudio SR01 Ultrasonic sensor is a very affordable and detects the distance between the ultrasonic sensor and obstacle. It adopts CS100A chip, compatible with 3.3V and 5V. Its maximum detection distance is 3m and blind area is less than 4cm.
As same as the principle of the bat, ultrasonic module sends a high frequency signals that the human body cannot hear. They will travel back if encountering the obstacle. On receiving the returned information, it will calculate the distance between the sensor and the obstacle by determining the time difference of the transmitted signal and the received signal.
