HC-SR05 PRECISION ULTRASONIC DISTANCE SENSOR

Ultrasonic sensors overcome many of the weaknesses of IR sensors – they provide distance measurement regardless of colour 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 particular model is an upgrade from the lower precision HC-SRO4. This has 5 pins and can be used in 1-pin trigger/echo or 2-pin.

• 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.
