SunFounder 1 pc Ultrasonic Module HC-SR04 Distance Sensor

Description

SunFounder 1 pc Ultrasonic Module HC-SR04 Distance Sensor
for Arduino UNO MEGA R3 Mega2560 Duemilanove Nano Robot XBee ZigBee
No wiring, module still in packaging.
Features
Ultrasonic hc-sr04 distance measuring transducer sensor, it consists of an ultrasonic transmitter, receiver, and a 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 an 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 an ultrasonic transmitter, receiver, and a control circuit. Mode of Connection: VCC/ trig(T)/ Echo(R)/ GND (VCC supply 5V, and GND is a ground wire. TRIG is trigger control signal input, ECHO is echo signal output.)
