The SW-520D is a low-cost, roller-ball type tilt and vibration switch that detects orientation changes or physical shaking by using a moving metal ball to open or close an electrical circuit

Module features:

1, using the highly sensitive SW-520D switch as the sensor angle.

2, the comparator output signal is clean, good waveform, driving capacity, more than 15mA.

3, operating voltage 3.3 V-5 V

4, output format: digital output switching (0 and 1)

5, a fixed holes for easy installation

6, small PCB board size: 3.2 cm x 1.4 cm

7, using a large LM393 voltage comparator

Form for use

1, wiring the electrical diagram module below, are described in detail;

2, the output module depends on the position of the switch is on and off, when the angle goes off, the output of the DO converter is ON, low output DO;

3, the output can be directly connected to the microcontroller through the microcontroller to detect high and low, thus detecting the change from above;

4, the output of the module can directly drive the relay, which can be composed of a high switching angle angles to protect electrical equipment and other products when it has automatically turned off function.

Max Voltage: 12V to 20V DC
Max Current: 20mA to 30mA
Closed Resistance: Less than 10 ohms
Open Resistance: Greater than 10 megaohms
Trigger Angle: Usually closes or opens when tilted beyond roughly 15 degrees from the horizontal position
