HC-SR04 DC 5V Ultrasonic Module Distance Measuring Sensor
Ultrasonic Sensor module is a transmitter, receiver, and a control circuit. It has a handy and compact build. The operation of this ultrasonic sensor is not affected by sunlight or black material like Sharp rangefinders (although acoustically soft materials like cloth can be difficult to detect). Measures the distance within a wide range of 2cm to 450cm | Stable performance | Accurate distance measurement | High-density | Small blind distance Dimensions: PCB size(LxW):45x20mm | Sensor cover diameter:16mm The Ultrasonic Sensor uses ultrasonic waves to determine the distance of an object. Therefore, it can be used as a distance measuring sensor. It can be used to measure the depth of water as waves can travel in water, detect and avoid obstacles in the path of a robot and also as a parking assist sensor.
