fresh and wonderful Material: Electronic ingredient Color: See pictures Two main technical parameters: Voltage: 5V DC Quiescent Current: <2mA Level Output: the output of the high-5V Level: The end of 0V Induction Angle: not more than 15 stages Detection Range: 2cm-450cm High precision: Up to zero Panel Wiring, VCC, trig 's (control side), the echo (receiving end), out (empty feet), GND TRIP-pin internal pull-up 10K resistor, down TRIP microcontroller IO port pin, after which to a 10us pulse signal. OUT pin for this module because the change output pin when the anti-theft module, ranging modules do not use this foot! The module ought to be inserted Fortunately, the circuit board re-energized, and keep away from the excessive malfunction, in the event that they have re-energized before they solve. This module could be provided ranging program: C51, PIC18F877 microcontroller Yoshitatsu 3 MCU investigate reference. The module URF04 works: IO set off ranging to at the very least 10us high signal; Module mechanically sends eight 40kHz square wave, routinely discover whether or not a sign return; A sign to come back to a excessive IO output, excessive duration of the ultrasonic time from launch to return. Test distance = (time excessive * speed of sound (340M / S)) / 2; Size: 4*2*1/1"*0"*0" No Retail Packages Quantity:1Pc Note: Due to the difference between varied monitors, the image won't mirror the particular coloration of the item. Thank you!
