Ultrasonic distance sensor HC-SR04 2-400cm - SparkFun SLEEP-15569

Ultrasonic sensor with an operating rangefrom 20 mm to 4000 mm, with a tolerance of 3 mm. The module consists oftransmitter,receiverandcontrol circuit. The operating principle of HC-SR04 is based on measuring the duration of the output signal, which is proportional to the distance between the sensor and the object. The device is powered by5 V.

Ultrasonic sensor HC-SR04.

The ultrasonicdistancesensor has four leads:

• VCC: supply voltage
• Trig: sensor input (excitation)
• Echo: sensor output (answer)
• GND: system weight
