HC-SR05 Ultrasonic Distance Sensor

The HC-SR05 is an evolutionary step from the HC-SR04and has been designed to increase precision and stability.As such, the HC-SR05 is fully compatible with the HC-SR04, both are ultrasonic sensors that ping a sound wave with a transmitter and measure the distance that ping took to return to the receiver. The only difference between them is the HC-SR05 sensor has an extra pin labeled OUT, but for most practical purposes, this pin will not be needed.Specifications:Power supply: 5V dc,Quiescent current: <2 mA,Range: 2 cm - 450 cm,Resolution: 0.3 cm,Blind spot: 2 cm.Connections:New PingLibrary
