Specifications:
This module performance and stability, accurate measurement of
distance, SRF02 comparable ultrasonic ranging module. Module of
high precision, blind area (2cm ) super close, stable range is the
success of this product to market the strong basis!

This product use: a control orifice with a 10US above high level,
can be in the receiving port to wait for high level output.
The output of the timer can be opened, when the orifice is low we
can read the timer value, this time for the ranging time,
We can calculate the distance. So continuous cycle test, can
achieve your mobile measurement value ~ ~
Module working principle:
(1) using IO trigger location, to at least10us high level signal;
(2) module to automatically send8 40KHz square wave, to
automatically detect whether a signal return;
(3) a return signal, through the IO outputs a high level, high
level for a time is
Ultrasonic wave from the transmitter to the return time. Testing
distance = ( high level time * speed of sound (340M/S ) ) /2;
Competitive Advantage:
1. Convenient & Friendly Customer Service
2. Low Prices Direct From Factory Suppliers
3. Fast Delivery Around the World.
4. High Quality With Global Standards.
5. 1 Year Factory Warranty
6. Safe Shipping Way and Payment
