5pcs/lot Ultrasonic Module HC-SR04 Distance Measuring

HC-SR04 Distance Sensor Module consists of ultrasonic transmitter, receiver, and control circuit. Connection mode: VCC, trig (control), echo (receiving end), GND ground wire. 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. Ultrasonic Sensor Module Working Principle: 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, The signal to return, a high IO output, high duration of. Technical Specification: Working voltage: DC3.3-5V Quiescent current: < 2mA Level output: High 5V Level output: Bottom 0V Sensing angle: < 15° Measuring Angle: 30° Detection range: 2cm-450cm High precision: up to 0.3cm Package include: 5 x HC-SR04 Ultrasonic Sensors
