Songhe HC-SR04 Ultrasonic Sensor Module Distance Measuring Sensor Module for Arduino UNO MEGA2560 Nano (5pcs)

Voltage: DC5V;Quiescent Current: <2mA;level output: the output of the high-5V;level: the end of 0V;Induction Angle: not more than 15 degrees: detection range: 2cm-450cm;High precision: up to 0.3cm
the module HC-SR04 works: (1) IO trigger ranging to at least 10us high signal; (2) module automatically sends eight 40kHz square wave, automatically detect whether a signal return; (3) a signal to return to a high IO output, high duration of the ultrasonic time from launch to return.
Panel wiring, VCC, trig 's (control side), the echo (receiving end), out (empty feet), GND
Note: TRIP-pin internal pull-up 10K resistor, down TRIP microcontroller IO port pin, and then to a 10us pulse signal.
OUT pin for this module as the switch output pin when the anti-theft module, ranging modules do not use this foot!
Note: The module should be inserted Fortunately, the circuit board re-energized, and avoid the high malfunction, if they have re-energized before they solve.
