Keyes Brick HC-SR04 Ultrasonic Sensor Module Anti-reverse Plug White Terminal

Specification 1 Voltage DC5V 2 Quiescent Current 2mA3 level output the output of the high 5V 4 level the end of 0V5 Induction Angle not more than 15 degrees6 Detection range 2cm 450cm7 High precision up to 0 3cm Panel wiring VCC trig s control side the receiving end out empty feet GNDNote Pin internal pull up 10K resistor down 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 This module can be provided ranging program C51 PIC18F877 microcontroller Yoshitatsu three MCU test reference 3 the module URF04 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 This product is simple to use and a Control Port high above a 10US you can wait for the high output at the receiving port An output can open the timer can be read when this port goes low timer value for the time ranging be calculated distance such a continuous cycle of measurement you move to measure the value we can achieve The module works 1 IO trigger ranging to at least 10us high signal 2 module au
