Ultrasonic Module HC-SR04 Distance Measuring Transducer Sensor for arduino uno r3, mega, raspberry pi
Working Voltage: 5V DC; quiescent current: < 2mA; effectual angle: less than 15°; distance: 2cm~400cm; resolution: 0.3 cm
Output signal: Electric frequency signal, high level 5V, low level 0V
HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. When trigged it sends out a series of 40KHz ultrasonic pulses and receives echo from an object.
Test mode :Using IO trigger for high level signal.( Not less that 10us),The Module sends eight 40 kHz automatically and detect whether there is a pulse signal back.
