SunFounder 2pcs HC-SR04 Distance Sensor for Arduino UNO MEGA R3 Mega2560 Duemilanove Nano Robot Rapsberry Pi 3, 2 & RPi Model B+ XBee ZigBee
- Product Description
- Ultrasonic hc-sr04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit.
- HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal，When triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object.
- Hc-sr04 Test Distance following formula: L = 1/2 × T × C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed)
- Power Supply : 5V DC; Quiescent Current : <2mA,; Effectual Angle: <15° ; Detection Distance : 2cm~450 cm; Resolution : 0.3 cm
SunFounder HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. Mode of Connection: VCC/ trig(T)/ Echo(R)/ GND (VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output.)
