Highlights

• Compatible with Arduino, NodeMCU
• Adopt IO trigger through supplying at least 10us sequence of high-level signal
• The module automatically send eight 40khz square waves and automatically detect whether receive the returning pulse signal
• If there are signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving
• This is an ultrasonic sensor distance measuring module which a non-contact distance measurement module. It has high measurement accuracy and its blind area is close (up to 2cm)

Specification

This module measures the distance accurately. performance nearly the same as SRF05, SRF02 SRF05, SRF02 ultrasonic distance measuring module, and other comparable. Module High precision, blind spots (2cm) super close.
