Ultrasonic Ranging Sensor HC-SR04

Description The HC-SR04 Ultrasonic Distance Sensor is used for detecting the distance to an object using sonar. It’s ideal for robotics projects your have which require object avoidance, by detecting how close they are to steer away from them. The lower supply voltage range makes this compatible with micro: bit as well as Arduino and other boards. Specifications: Power Supply: 3-5V DC Effectual Angle : < 30 degrees Ranging Distance: 2cm to 500 cm Resolution : 1cm Ultrasonic Frequency: 40kHz Use: Check out this great info page on HC-SR04 sensors: Last Minute Engineers Project Example: Instructables Get a bracket to hold the sensor: Here   Packing List: 1x HC-SR04 Sensor
