Varenummer: 2017 Kategori:

This module performance is stable, measure the distance accurately. performance nearly the same as SRF05,SRF02 ultrasonic distance measuring module and other comparable. Module High precision, blind spots (2cm) super close. Specification: 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-510cm High precision: 3mm Wiring: VCC, trig (control side), echo (receiving end), GND Module Working Principle: Using IO trigger distance, the high signal to at least 10us Module automatically sends eight 40khz square wave, automatically detects whether a signal return If there is 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;
