خواهش میکنم کمکم کنید
تو یه فروش گاه دیگه واسه توضیحات اینارو نوشته بود :
نقل قول: Description:
Sensor can sense changes in body angle (accuracy can reach 15-45 degrees)
Adjustable sensitivity (shown in blue digital potentiometer adjustment)
Operating Voltage 3.3V-5V
Output format: digital switching outputs (0 and 1)
With fixed bolt hole for easy installation
Small PCB board size: 3cm * 1.6cm
Power indicator (red) and the digital switch output indicator (green)
Using LM393 comparator chip, stable
Life: at room temperature and normal life of up to 100,000 times switch (times / 1sec).
Interface Description (3-wire):
VCC external 3.3V-5V
GND GND External
DO digital output interfaces (0 and 1)
Instructions for use:
Tilt switch sensor using MEC original SW-460D, high sensitivity
DO digital output interface can be directly connected to the microcontroller IO port
Application:
Tire Pressure Monitoring System (TPMS), bicycle lights, digital photo frame rotation, screen rotate, flip video camera, anti-theft system
Test Description:
51 development board with tilt sensor module test
Module VCC connected to development board VCC
Module GND connected to development board GND
Connect the VCC and GND, module power indicator lights
The module level light up on the desktop, the module slowly rotating in one direction, the switch indicator lights, and then rotate in the opposite direction module back to the original state, the switch light off. This phenomenon is explained, changing the angle of the sensor can trigger module, so that the switch indicator lights.
