DS3231 RTC Real Time Clock Memory Module
This module performance and stability, accurate measurement of distance. Can be comparable with SRF05, SRF02 ultrasonic ranging module.Module of high precision, blind area (2cm ) super close, stable range is the success of this product to market the strong basis!
Main technical parameters: 1. Voltage: DC5V2. Static current is less than 2mA3. Output: high 4: low level output:5V5. Induction angle: not more than 15 DEG6. Detecting distance:2cm-450cm7. High precision: up to 3mm
Module working principle: (1) using IO trigger location, to at least10us high level signal; (2) module to automatically send8 40KHz square wave, to automatically detect whether a signal return; (3) a return signal, through the IO outputs a high level, high level for a time is Ultrasonic wave from the transmitter to the return time. Testing distance = ( high level time * speed of sound (340M/S ) ) /2.
