The Keyestudio SR01 CS100A Ultrasonic Sensor V3 is an affordable and precise distance measurement module compatible with 3.3V and 5V systems. This makes it more versatile compared to the HC-SR04. It uses the CS100A chip to emit high-frequency ultrasonic signals, which reflect off obstacles and return to the sensor. By calculating the time difference between sending and receiving these signals, it accurately measures distances up to 3 meters, with a blind zone of less than 4 cm. This sensor is ideal for applications requiring reliable obstacle detection and distance sensing.
