HC-SR04 Ultrasonic Distance Measuring Transducer Sensor Module kit arduino
Description:
Ultrasonic HC-SR04 Distance Measuring Transducer Sensor, using IO trigger for at least 10us high level signal
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.
The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse.
power supply :5V DC
quiescent current : Less than 2mA
effectual angle: Less than 15 degree
ranging distance : 2cm – 450 cm
resolution : 0.3 cm
Size: 30*15mm
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.)
