Product Overview
Features:
Specification:
Operating Voltage: DC5V
Static Current: <2mA
Level Output: High 5V, Low 0V
Sensing Angle: ≤15°
Detecting Distance: 2cm-450cm
Accuracy: 0.3cm
Wiring: VCC, trig(control terminal), echo(reception terminal), out(empty), GND
Module Working Principle:
1. Adopt IO trigger through supplying at least 10us sequence of high level signal.
2. The module automatically send eight 40khz square waves and automatically detect whether receive the returning pulse signal.
3. If there is signals returning, output high level through IO, the continuance time of high level is the time of that from the ultrasonic transmitting to receiving. Measuring distance = (high level time * sound velocity (340M/S) / 2.
Package list:
5 x Ultrasonic Ranging Module
Note:
1. The module should be inserted in the circuit before power-on, which avoid producing high level of misoperation; If not, then power again.
2. The TRIP pin is an internal pull-up 10K resistor. Pull down the TRIP pin by the IO port of the microcontroller and give a pulse signal of 10us or more.
3. The OUT pin is the switch output pin when the module is used as the anti-theft module. The distance measuring module does not need this pin!
