Parameter:

1: Voltage: DC5V

2: Static current: less than 2mA

3: level output: 5V high

4: level output: bottom 0V

5: Induction angle: not more than 15 degrees

6: Detection range: 2cm-450cm

7: High precision: up to 0.3cm

Wiring board, VCC, trig (control terminal), echo (receiving side), out (air foot), GND

NOTE: TRIP pin 10K pull on the internal resistance, TRIP pin pulled low by the microcontroller IO port and a pulse signal to one or more 10us.

Switch output pin OUT pin when the module as a module for this purpose, ranging module without this pin!

Note: good interpolation module circuit board should then power, to avoid erroneous operation of the high-level, if generated, re-energized only solution.

This module may provide a ranging procedure: C51, PIC18F877, microcontroller Yoshitatsu three test reference MCU.

This product is simple to use, at least one control port send a 10US high, high output can wait in the receiving opening. There are a timer output can be opened, when this goes low port can be readvalue of the timer, this time as the time ranging, only calculate the distance. this constant cycle of measurement, you can reach the value of the mobile measurement ~ ~

Works:

(1) The IO trigger distance, a high level signal to the at least 10us;

(2) module automatically sends eight 40khz square wave, automatically detects whether a signal return;

(3) a signal is returned, through the IO outputs a high level, the high level duration time is emitted from the ultrasonic wave to the return time.Test distance = (high level time * speed of sound (340M / S)) / 2;
