Description

متحسس المسافة بالموجات فوق الصوتية

يتميز هذا الجهاز بأداء مستقر ودقة عالية في قياس المسافة. أداؤه مماثل تقريبًا لأجهزة قياس المسافة بالموجات فوق الصوتية SRF05 وSRF02 وغيرها من الأجهزة المماثلة. يتميز الجهاز بدقة عالية، مع نطاق رؤية ضيق للغاية (حتى 2 سم).

1.This module performance is stable, measure 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.
2.Main technical parameters:
Voltage: DC 5V
Static current: less than 2mA
Electrical level output: 5V high
Electrical level output: at the end of 0V
Induction angle: not more than 15 degrees
Detection distance: 2cm-450cm
High precision: 2mm
Wiring: VCC, trig (control side), echo (receiving end), GND
3.Module works:
using IO trigger distance, the high signal to at least 10us
module automatically sends eight 40khz square wave, automatically detects whether a signal return;
a signal back, through the IO output a high electrical level, high electrical level duration is: the ultrasound time from launch to return. Test distance = (time of the high electrical level * speed of sound (340M / S)) / 2;
