Features: Mode of connection: 1.VCC 2.trig(T) 3.echo(R) 4.GND Use method: Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not. The out pin of this module is used as a switching output. When anti-theft module, and without the feet when ranging modules.
Description: HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal The hc-sr04 arduino 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
Specifications: DIY Supplies: Electrical Electrical level output: 5V high High precision: 2mm Working Voltage : 5V(DC) Static current: Less than 2mA. Hc-sr04 Test Distance : high level time velocity of sound (340M/S) /2 Output signal: Electric frequency signal, high level 5V, low level 0V. Sensor angle: Not more than 15 degrees. Detection distance: 2cm-450cm. High precision: Up to 0.3cm Input trigger signal: 10us TTL impulse Echo signal : output TTL PWL signal Color: Blue & Silver Item size: 45*20*16mm
