Longruner 5 x HC-SR04 Ultrasonic Sensor, Arduino Distance Sensor UNO Nano Robot XBee ZigBee with Ultrasonic Transmitter and Receiver Module
The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats do. </br> It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. From 2cm to 500 cm or 1" to 13 feet. </br> It operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect).</br> It comes complete with ultrasonic transmitter and receiver module. </br> </br> <b>Features: </b></br> Power Supply: +5V DC</br> Quiescent Current: <2mA </br> Working Current: 15mA</br> Effectual Angle: <15°</br> Ranging Distance: 2cm - 500 cm/1″ - 13ft </br> Resolution: 0.3 cm </br> Measuring Angle: 30 degree</br> Trigger Input Pulse width: 10uS </br> Dimension: 45mm x 20mm x 15mm Pins </br> VCC: +5VDC </br> Trig: Trigger (INPUT)</br> Echo: Echo (OUTPUT) </br> GND: GND </br> </br> <b>Package includes:</b></br> 5* HC-SR04 Ultrasonic Distance Sensor</br> 1*HC-SR04 Bracket</br> 1*Male to Femal jump wires 20pin</br> 10*cable ties for fixing HC-SR04(as a gift)</br> </br> <b>NOTE: </b></br> If the HC-SR04 does not receive an echo then the output never goes low. Devantec and Parallax sensors time out after 36ms and I think 28ms respectively. If you use Pulsin as above then with no return echo the program will hang for 1 second which is the default timeout for Pulsin. You need to use the timeout parameter.</br> </br> If you have any question, please be free to contact us, we will try our best to help you.</br> <b>Service Email: [email protected]</b></br>
