Description
Longruner 5 x HC-SR04 Ultrasonic Sensor, for ArduinoIDE Distance Sensor 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. 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. 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). It comes complete with ultrasonic transmitter and receiver module. Features: Power Supply: +5V DC Quiescent Current: Working Current: 15mA Effectual Angle: Ranging Distance: 2cm – 500 cm/1″ – 13ft Resolution: 0.3 cm Measuring Angle: 30 degree Trigger Input Pulse width: 10uS Dimension: 45mm x 20mm x 15mm Pins VCC: +5VDC Trig: Trigger (INPUT) Echo: Echo (OUTPUT) GND: GND Package includes: 5* HC-SR04 Ultrasonic Distance Sensor 1*HC-SR04 Bracket 1*Male to Femal jump wires 20pin 10*cable ties for fixing HC-SR04(as a gift) NOTE: 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.
