HY-SRF05 SRF05 Ultrasonic Distance Sensor Module Replace SR04 5 Pin for Arduino

Ultrasonic sensors overcome many of the weaknesses of IR sensors - they provide distance measurement regardless of color and lighting of obstacles. They also provide lower minimum distances and wider angles of detection to guarantee that obstacles are not missed by a narrow sensor beam. This model is an upgrade from the lower precision HC-SR04. This has 5 pins and can be used in 1-pin trigger/echo or 2-pin. Use these formulas to calculate distance: Distance (in cm) = (elapsed time * (340 m/s)) / 50 Distance (in inches) = ((elapsed time * (340 m/s)) / 50) * 0.393701 Specifications Trigger Pin Format: 10 uS digital pulse Sound Frequency: 40 kHz Echo Pin Output: 0-Vcc Echo Pin Format: output is DIGITAL and directly proportional with range. See our conversion formula above. Measurement Range: 2cm to ~4.5m Measurement Resolution: 0.3cm Measurement Angle: up to 15 deg Measurement Rate: 40 Hz Supply Voltage: 4.5V to 5.5V Supply Current: 10 to 40mA Connector: standard 5-pin male connector which can plug directly into breadboards. Package Included: 1 x HY-SRF05 SRF05 Ultrasonic Distance Sensor Module Replace SR04 5 Pin for Arduino Instructions/schematic are NOT included.
