Description
- 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.
