Description

The SW-18020P Vibration Sensor Module integrates a high-sensitivity SW-18020 series vibration switch with a signal-conditioning comparator circuit. The spring-type switch mechanism is non-directional, meaning it can be triggered by vibration from any angle, making it suitable for omnidirectional detection applications. The onboard LM393 comparator provides a stable digital output signal, simplifying interface with digital input pins on microcontrollers or logic circuits.

Constructed for durability across a wide temperature span, this module is designed for integration into various electronic and electromechanical systems where shock or vibration detection is required for operational monitoring or safety interlocks.

Key Features

  • High-sensitivity, spring-type vibration switch for reliable omnidirectional detection.
  • Integrated LM393 comparator ensures clean, bounce-free digital output signals.
  • Wide operating voltage compatibility from 3.3V to 12V DC.
  • Robust construction rated for operation from -40°C to +80°C.
  • Convenient mounting hole provided for secure mechanical installation.
  • Low current consumption, with a maximum draw of 50mA.
  • Output can directly drive LEDs, buzzers, or relay coils (drive capability >15mA).

Applications

  • Anti-theft and intrusion detection alarms for cabinets or enclosures.
  • Vibration monitoring in home appliances like washing machines or air conditioner units for fault detection.
  • Impact or drop detection in portable consumer electronics and sports equipment.
  • Machine condition monitoring for industrial equipment to signal unusual vibration.
  • Automotive security systems for detecting tampering or attempted theft.

Frequently Asked Questions

What is the operating voltage range for the SW-18020P module?

The SW-18020P Vibration Sensor Module operates on a wide DC voltage range from 3.3V to 12V. This makes it compatible with common 5V Arduino boards as well as 3.3V logic systems like Raspberry Pi or ESP32 without requiring a level shifter.

How does the output signal work, and how do I wire it to my microcontroller?

The module provides a clean digital output via the onboard LM393 comparator. The output pin is typically active LOW, meaning it goes to a logic low (0V) state when vibration is detected. Connect the VCC and GND pins to your power supply, and the signal (OUT) pin to a digital input pin on your MCU. A pull-up resistor (often internal to the MCU) may be required for a stable high state.

Is the sensor directional, and how sensitive is it?

No, the SW-18020P uses a spring-type, non-directional vibration switch. It can be triggered by physical shock or vibration from any angle. Sensitivity is inherent to the mechanical spring design; it responds to sufficient acceleration or impact, making it suitable for general-purpose shock detection rather than precise vibration measurement.

Can this module be used outdoors or in harsh environments?

While the module has a robust operating temperature range (-40°C to +80°C), the PCB itself is not conformally coated or sealed against moisture. For outdoor or harsh industrial use, the module should be housed in a protective, IP-rated enclosure to prevent damage from water, dust, or condensation.
