Paradisetronic.com Ultrasonic sensor HC SR04 with bracket, distance measurement up to 3m, for e.g. Arduino, Raspberry Pi

HIGH MEASUREMENT ACCURACY - The HC-SR04 ultrasonic sensor delivers accurate distance measurements with an accuracy of up to 3mm. Distances of up to 3m can be measured. SIMPLE CONTROL - The board has two supply pins (VCC, GND) and two lines for measuring the distance. A high signal at the connection labeled "Trig" triggers a measurement process. SIMPLE DISTANCE CALCULATION - As soon as the signal has been received, this is output at the "Echo" output. The distance is calculated as follows: Distance in m = t in s * speed of sound (approx. 340 m / s) / 2 INCLUDING HOLDER - With the practical holder, the sensor is ideally suited for the implementation of robots or autonomous vehicles. Screws are not included. PROVEN QUALITY - If you have reason to complain despite our quality controls, we at Paradisetronic will help you quickly and easily.
