Description
- HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal
- 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 out puted by IO, and the duration of the signal is the time from sending ultrasonic to returning
- HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. When trigged it sends out a series of 40KHz ultrasonic pulsesand receives echo from an object.Hc-sr04 Test Distance : high level time velocity of sound(340M S)
- Power supply: 5V DC; quiescent current: less than 2mA;effectual angle: less than 15°; distance: 2cm500cm; resolution: 0.3 cm
- Package Content: 5pcs HC-SR04 in the antistatic resealable bag with a gift.
