Featuring a wide voltage LM393 comparator, it delivers clean digital output signals (0 or 1) across a 3.3V-5V range. Its adjustable sensitivity and easy mounting options make it ideal for security alarms, motion detection, and interactive electronics, backed by strong user reviews praising its responsiveness and value. ## Description Hiletgo 5pcs SW-420 Vibration Sensor Module Vibration Switch Alarm Sensor Module for Arduino 1, using SW-420 normally closed type vibration sensor. 2, the comparator output signal clean waveform is good, driving ability,>15mA 3, working voltage 3.3V-5V 4, Output format: Digital switching output (0 and 1) 5, with bolt holes for easy installation 6, small plate PCB size: 3.2cm x 1.4cm 7, using a wide voltage LM393 comparator Package Include: 5* Vibration sensor module Review: Extremely sensitive, which I like - You can adjust the sensitivity, but it seems to lean hard toward the extremes. Just tapping a solid surface can set it off, which I love. Review: Good devices - Very good. Very sensitive but not too much false alarm. Sensitivity seems responsive to adjustment. Overall very good device and value. ## Features - Hiletgo SW-420 Vibration Sensor Module - Output format: Digital switching output (0 and 1) - Working voltage 3.3V-5V - With a wide voltage LM393 comparator ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 101 Reviews | ## Images ![Hiletgo 5pcs SW-420 Vibration Sensor Module Vibration Switch Alarm Sensor Module for Arduino - Image 1](https://m.media-amazon.com/images/I/61z9YAWCXzL.jpg) ## Questions & Answers **Q: Can I attach these to a washing machine and a dryer to detect if they are running?** A: Very possible but why! **Q: what is the a minimum force threshold be configured? For example, can it be set to identify detect a 25 kN of force of higher?** A: ANSWER IS NO!. 12 kn of force, would not work with a piezoelectric element. This control is for small vibrations like knocking on door or awning that wind swings in the breeze. **Q: How sensitive is this sensor? For example, if I put this inside a model railroad freight car - would it be able to sense if the car is moving or not?** A: Absolutely, Sub-G reading capable...will detect rail car motion via vibration. Problem you’ll have to surmount is they are so sensitive, discriminators in the code will be required to remove the noise of the car standing still, as well as other vibrations from near by things. Good luck **Q: Does this produce some square wave matching the vibration, or does the output just remain on for a period of time once it detects a vibration?** A: Yes. You may use counter to determine number of vibrations by logging pulses. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Extremely sensitive, which I like *by A***R on June 10, 2023* You can adjust the sensitivity, but it seems to lean hard toward the extremes. Just tapping a solid surface can set it off, which I love. ### ⭐⭐⭐⭐⭐ Good devices *by R***H on October 16, 2019* Very good. Very sensitive but not too much false alarm. Sensitivity seems responsive to adjustment. Overall very good device and value. ### ⭐⭐⭐⭐ Senses vibration, out puts a digital signal *by B***E on January 29, 2022* Device does what it should, the adjustment is VERY sensitive. Signal is very brief, but if you’re looking for a quick trigger DO, this does the job ## Frequently Bought Together - Hiletgo 5pcs SW-420 Vibration Sensor Module Vibration Switch Alarm Sensor Module for Arduino - MakerHawk 4pcs Analog Ceramic Piezo Vibration Sensor Module 3.3V/5V for Arduino DIY Kit - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/82422312-hiletgo-5pcs-sw-420-vibration-sensor-module-vibration-switch-alarm](https://www.desertcart.ie/products/82422312-hiletgo-5pcs-sw-420-vibration-sensor-module-vibration-switch-alarm) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-03*
