Effective angle: \u0026lt;15°. Ranging distance: 2 cm - 500\ncm. Resolution: 0.3 cm. Mode of connection: VCC\/trig(T)\/ Echo(R)\/ GND. (VCC\nsupply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO\nis echo signal output.) Attention: 1.The module should be inserted in the\ncircuit before been powered to avoid producing high level of misoperation; if\nproducted, power it again. 2.The module is not suggested to connect directly\nto electric, if connected electric, the GND terminal should be connected the\nmodule first, otherwise,it will affect the normal work of the module. 3.When\ntested objects, the range of area is not less than 0.5 square meters and the\nplane requests as smooth as possible, otherwise ,it will affect the results of\nmeasuring. Package includes: 5 x HC-SR04 ultrasonic sensors.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eHC-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\u003c\/li\u003e\n         \u003cli\u003eHC-SR04 test distance: high level time velocity of sound (340M\/S) \/2\u003c\/li\u003e\n         \u003cli\u003eEquipped with anti-reverse pin socket  making the wiring much tighter and convenient; 4-pin anti-reverse cable also included.\u003c\/li\u003e\n         \u003cli\u003eUses the MCU STC15W104 which has a built-in clock, no need of external crystal oscillator.\u003c\/li\u003e\n         \u003cli\u003eHC-SR04 power supply: 5V DC; quiescent current: \u0026lt;2mA; effective angle: \u0026lt;15; detection distance: 2 cm ~ 500 cm; resolution: 0.3 cm\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Hailege","offers":[{"title":"Default Title","offer_id":45749937373337,"sku":"de-B07XF4815H","price":119.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0491\/3148\/7385\/files\/de-B07XF4815H.jpg?v=1775754376","url":"https:\/\/soundstores.net\/products\/hailege-5pcs-hc-sr04-ultrasonic-distance-sensor-ultrasonic-sensor","provider":"SoundStore Australia","version":"1.0","type":"link"}
