Ultrasonic hc-sr04 distance measuring transducer sensor.
HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. When trigged it sends out a series of 40KHz ultrasonic pulses and receives echo from an object..
Package Content: 5pcs HC-SR04 with a little gift.

Ultrasonic module distance measuring transducer sensor..
HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. When trigged it sends out a series of 40KHz ultrasonic pulses and receives....
Power Supply: DC 5V, Quiescent Current: less than 2mA.
Compatible with DIY Robot Car/Raspberry Pi 4B, 3B+, 3B.

The HC-SR04 ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning.
HC-SR04 Test Distance : high level time velocity of sound (340M/S) /2.
Equipped with anti-reverse pin socket – making the wiring much tighter and convenient.
Uses the MCU STC15W104 which has a built-in clock, no need of external crystal oscillator..
