VIRIMA HC-SR04 Ultrasonic Distance Measuring Sensor for arduino Electronic Components Electronic Hobby Kit

This is an ultrasonic distance sensor, model HC-SR04. With a range accuracy that can reach up to 3mm, this affordable sensor offers non-contact measurement functionality from 2 cm to 400 cm. An ultrasonic transmitter, a receiver, and a control circuit are all included in each HC-SR04 module. The HC-SR04 only has four pins that require attention: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). This sensor is really simple to set up and utilise for your upcoming range-finding project! Depending on the application, this sensor's additional control circuitry can avoid inconsistent or "bouncy" data.
