Pins Details
5-Pin, One each for VCC, Trigger, Echo, Out and Ground.
Trig
: Plusing a HIGH on this pin will send a Pulse
Echo
: The pulse length is propotional to the distance from the obstacle ( 100usec to 25ms, times out if 30ms)
Specifications
Check the datasheet for details and graphs but these are the highlights:
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.
Static current :
less than 2mA
Detection distance:
2cm-450cm
Usage:
10US a control population of more than a high-fat, you can wait to receive high output port. A timer can be opened with the output timing, when the port goes low when the timer value can be read this when the time for this distance, only calculate the distance. This constant cycle of measurement, you can reach the value of the mobile measurement
The basic principle of work:
Using I/O trigger for at least 10us high level signal The module automatically sends eight 40KHz and detect whether there is a pulse signal back If the signal back, through high level, time of high output IO duration is the time from sending ultrasonic to returning Test distance = high level time x velocity of sound (340m/s) / 2 Display Format: 16 Characters x 2 lines
