Description:
The performance of this module is stable and precise measure of distance. And comparable foreign SRF05, SRF02 Ultrasonic Ranging Module. Module precision, blind spots (2cm) super close, stable distance measurement is strong based on this product successfully to market! This module is completely modest capacity of GH-311 anti-theft module.
Specifications:
1. Voltage: DC5V
2. Quiescent Current: <2mA
3. level output: the output of the high-5V
4. level: the end of 0V
5. Induction Angle: not more than 15 degrees
6. detection range: 2cm-450cm
7. High precision: up to 0.3cmi
The Module URF04 Works:
(1) IO trigger ranging to at least 10us high signal;
(2) module automatically sends eight 40kHz squre wave, automatically detect whether a signal return;
(3) a signal to return to a high IO output, high duration of the ultrasonic time from launch to return.
Test distance = (time high * speed of sound (340M / S)) / 2;
This product is simple to use, and a Control Port high above a 10US, you can wait for the high output at the receiving port. An output can open the timer can be read when this port goes low timer value for the time ranging be calculated distance. such a continuous cycle of measurement, you move to measure the value we can achieve
Package Include:
1×Distance Sensor Module Board
