Details:
1 This module performance is stable, measure the distance accurately. Energy and foreign SRF05, SRF02 ultrasonic distance measuring module and other comparable. Module precision, blind spots (2cm) super close, stable ranging success of this product to the market is strong under!
2 main technical parameters:
1: Voltage: DC5V
2: Static current: less than 2mA
3: level output: high-5V
4: level output: the end of 0V
5: Sensor angle: not more than 15 degrees
6: Detection distance: 2cm-450cm
7: High precision: up to 0.3cm
Wiring:
VCC, trig (control side), echo (receiving end), GND
This product uses the method: a control port made ​​a high of more than 10US, you can wait to receive high output port. A timer can be opened with the output timing, when this port goes low when you can read timing the value of this time on time for this distance, only calculate the distance. this constant cycle of measurement, you can reach the value of the mobile measurement ~ ~
3 module works:
(1) The IO trigger distance, high-level signal to at least 10us;
(2) the module automatically sends eight 40khz square wave, automatically detects whether a signal return;
(3) a signal back, through the IO outputs a high level, the duration of high level is ultrasonic time from launch to return. Test distance = (time * High speed of sound (340M / S)) / 2;
This module provides a full set of ranging process: C51, PIC18F877, ultrasonic LCD1602 display, ultrasonic LCD12864 display, digital display, serial display, ranging reference program.
