Ultrasonic sensor module hy-srf05, more precision than hc-sr04.
Product description:
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 distance and wider angels of detection to gaurantee that obstacles are not missed by a narrow sensor beam.
This particular model is an upgrade from the lower precision hcsr-o4. This has 5 pins and can be used in 1-pin trigger / echo or 2-pin.
Measurement procedure & formula:
Send a 10 us wide pulse to the sensor on the trigger pin. The sensor will automatically send out a 40 khz wave.
Begin monitoring the output from the echo pin and
When the echo pin goes high, begin a timer.
When the echo pin goes low, record the elapsed time from the timer and use the following conversion formula:
Distance = (elapsed time x sound velocity (340 m / s)) / 100 / 2
Note: We divide distance by 2 because the sensor returns the round trip time, which doubles the distance measurement.
Specifications feature:
Trigger pin format: 10 us digital pulse
Sound frequency: 40 khz
Echo output pin: 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
Measurements angle: Up to 15 deg
Measurement rate: 40 hz
Voltage supply: 4.5v to 5.5v
Current supply: 10 to 40ma
Working temperature: - 20c- + 60c
Size: 45x21mm (l x w)
Weight: 10g
Standard 5-pin male connector which can plug directly into breadbo
