Description
The SW-18010P Vibration Sensor Module is a highly sensitive shock and motion detection module designed for modern microcontroller projects. If you are looking for an affordable and reliable vibration sensor module price in BD, this component is the ideal choice for hobbyists and professionals alike. এটি মূলত একটি spring-type vibration switch যা যেকোনো ধরনের ঝাঁকুনি বা কম্পন সহজেই শনাক্ত করতে পারে।
Equipped with the robust LM393 voltage comparator chip, this module guarantees stable signal processing. Unlike basic 3-pin alternatives, this 4-pin variant provides both a Digital Output (DO) for direct high/low threshold triggers and an Analog Output (AO) for reading real-time vibration intensity. The onboard potentiometer allows you to easily adjust the sensitivity according to your environment, making it perfect for custom security and smart home systems.
Key Features & Benefits
- High-Sensitivity Element: Features the SW-18010P high-sensitivity spring-type vibration switch.
- Adjustable Threshold: Built-in multi-turn potentiometer for fine-tuning vibration trigger limits.

Frequently Asked Questions (FAQs)
1. What is the difference between DO and AO on the SW-18010P Module?
The DO (Digital Output) provides a simple high/low trigger (0 or 1) depending on whether the vibration crosses your set threshold. The AO (Analog Output) delivers a continuous voltage reading indicating the exact intensity of the shock or vibration.
2. How do I adjust the sensitivity of this vibration sensor?
You can adjust it using the onboard blue potentiometer. Turning it clockwise increases the threshold (makes it less sensitive), while turning it counter-clockwise makes it highly sensitive to minor vibrations.
3. What is the working voltage of the SW-18010P Vibration Sensor?
The module functions optimally within a voltage range of 3.3V to 5V DC, making it perfectly compatible with Arduino Uno, Raspberry Pi, ESP8266, and ESP32.
