This module features stable performance and accurate distance measurement. It is compare favourably with SRF05, SRF02 and other ultrasonic distance measuring modules. With high precision, ultra-close(2cm) blind area and stable performance.
Features:
Adopt IO trigger distance measuring, to at least 10us high-level signal.
Module automatically sends 8 40KHz square wave, automatically detect whether there is signal return.
If there is signal return, output a high level through the IO, the duration of high level is the time of ultrasound from the launch to the return.
Distance measurement = (high level time * sound speed (340M/S)) / 2.
Specifications:

Detection Range: 2cm ~ 450cm
Precision: Up to 0.3cm
Wiring: VCC, Trig(Control Terminal), Echo(Receiver), Out(Empty Foott), GND
Size(1pc): 45 * 20 * 13mm
Weight(1pc): 8g
Package Size: Approx. 7 * 6 * 3cm

Note:
1. TRIP pin is the internal pull-up 10K resistor, pull down TRIP pin with the MCU IO port, and then to a 10us or more pulse signal.
OUT pin as the switch output pin of anti-theft module for this module, ranging module does not use this foot!
2. The module should be installed on circuit board and then power on, avoiding high level; if generated, please re-power.
