Product Information

About

This knock sensor module is designed to detect vibration and shock signals in various interactive electronic projects. It can be used in DIY electronics projects, knock-controlled lighting, home appliances, interactive sensing devices, smart homes, vibration detection devices, security alarm systems, etc. Suitable for electronics DIY enthusiasts and professional developer.
You will get 3 Pcs x Sensor Module; Model Number: KY-031; Material: PCB; Voltage: 5V; Temperature Resisting: -20-50 ℃; Size: 18 x 14 mm/0.71 x 0.55 inch(L*W)
The knocking sensor is encapsulated in a glass shell, resulting in a simple and compact structure that is easy to install and integrate into various physical structures. The KY-031 can more sensitively capture small-amplitude vibrations or strike signals, providing real-time detection and quickly converting physical signals into electrical signals to meet the need for rapid response.
Easy to install, it features mounting bolt holes and a digital LED; the LED flashes when the strike sensor detects a strike signal. Solder the sensor pins to the circuit according to the circuit diagram. Please test the sensor response before use to confirm its trigger sensitivity.
For purchasing electronic components, modules should have some basic knowledge of electronics. Most modules only provide descriptions or information. Beginners should be cautious.
