HC-SR04 Ultrasonic Distance Measuring Transducer Sensor Module for Arduino The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object, just like bats do. It offers excellent non-contact range detection with high accuracy and stable readings from 2 cm to 400 cm (1 inch to 13 feet) with an accuracy of 3mm, in an easy-to-use package. Its operation is not affected by sunlight or black material like optical rangefinders are (although acoustically soft materials like cloth can be difficult to detect). The HC-SR04 comes complete with an integrated ultrasonic transmitter and receiver. Product Specifications:Working Voltage: 5 VDCStatic current: Less than 2mA.Output signal: Electrical frequency signal, high level 5V, low level 0VSensor angle: Not more than 15 degreesDetection distance: 2cm - 400cmAccuracy: Up to 3mmInput trigger signal: 10us TTL impulseEcho signal : Output TTL PWL signalItem size: 44mm * 20mm * 15mmNet weight: 11gramsMode of connection:VCC: 5V DC supply inputTrigger (T): Control signal input (10us TTL impulse) Echo (R): Echo signal output, duration is time from transmit to receiveGround GND: Ground wire HC-SR04 Ultrasonic Module Operation: Supply module with 5V, the Echo (R) output will be 5V while obstacle is in range, or 0V if it is not. Duration of Echo signal is used to calculate distance to object (see below). Use the IO port Trigger (T) to trigger ranging by applying a 10 us high level (TTL) trigger signal. The module will send an output square wave signal through its output acoustic transducer automatically, and will test if there is any signal returned to its input acoustic sensor. If there is an acoustic signal returned, The ECHO (R) IO port will have a high level signal. The duration of the high level signal is the time from transmit to receive using the ultrasonic transducers. Distance to object from module = Duration of ECHO (R) high level signal * sound velocity (340m/s) / 2 Package includes:1 x HC-SR04 Ultrasonic Distance Sensor ModuleLink to online specifications and operational documentation Get it faster!
