SW-420 Vibration Sensor Module

Description

The SW-420 Vibration Sensor is highly sensitive and precise in detecting vibrations and shocks, it is normally found in burglar alarms, earthquake detection systems, and interactive electronics. It provides a digital output signal based on detected vibration levels, allowing for seamless integration into electronic circuits and making it a reliable choice for vibration detection projects.

Operating in a normally closed configuration, this sensor employs a high-quality comparator, producing a clear signal with a robust driving capacity exceeding 15mA. Operating within a voltage range of 3.3V to 5V, it offers a digital switching output (0 and 1) suitable for microcontrollers. The module incorporates a wide voltage LM393 comparator and features convenient bolt holes for easy and secure installation.

The SW-420 module utilizes the SW-420 vibration sensor and LM393 comparator to detect vibrations beyond a preset threshold, which can be finely adjusted using an onboard potentiometer. In the absence of vibrations, the module outputs a logic LOW signal, causing the LED to illuminate, and vice versa. This output can be directly connected to a microcontroller to detect and respond to vibration levels, making it ideal for alarm systems.

It’s essential to avoid reversing power connections to prevent potential damage to the chip. The signal LED light indicates a LOW output when illuminated and a HIGH output when turned off, closely mirroring the input voltage. Overall, the efficient design and reliable performance of the SW-420 Vibration Sensor make it an excellent choice for various vibration detection applications.
