SW-520D Angle Sensor Module – High Sensitivity Tilt Switch
Features:
-
Utilizes the highly sensitive SW-520D tilt switch as the sensing element.
-
Clean comparator output signal with strong driving capability (>15mA).
-
Operating voltage: 3.3V – 5V DC.
-
Digital output signal (0 or 1) for easy integration with microcontrollers.
-
Equipped with mounting holes for quick and secure installation.
-
Compact PCB size: 3.2 cm x 1.4 cm.
-
Built with the reliable LM393 voltage comparator for stable performance.
Operating Principle:
-
The module detects angle changes based on the conduction state of the internal switch.
-
When the switch is open, the DO output is HIGH.
-
When the switch reaches the trigger angle and closes, the DO output goes LOW.
-
The digital output can connect directly to a microcontroller to detect tilt or orientation changes.
-
Can also directly drive a relay module, enabling applications such as automatic power shutoff and equipment protection.
Applications:
-
Tilt detection
-
Security and protection systems
-
Automation projects
-
Arduino and other microcontroller platforms
-
Motion or orientation-triggered devices
Package Includes:
✔ 1 × Gold SW-520D Angle Sensor Module
