Electronic module RPI-1031 Angle Sensor Four-Direction Sensor

Working Guidelines:

1. Protect Led by Cylindrical Shadow, Photosensitive Receiving Tube Is Used to Detect the Current State of RPI-1031.

2. When the RPI-1031 Is Rotated to the State (P1) as Shown in the Figure, the LED Is Covered by Shadow; the Two Photosensitive Receiving Triodes Cannot Receive Light; They Will Be in the off State and Output Low Level; both GPIO Ports Output Low Level.

3. When the RPI-1031 Is Rotated to the State Shown in Figure 2 (P2), One of the Photosensitive Triode Is Masked, and Only the Light Emitted by the LED Can Be Received by the Other; This Means That the above Photo Transistor Is Turned on, the Photo Transistor on the Side Is Disconnected; Then the Outputs of the Two GPIO Ports Output High and Low Levels Respectively.

4. When the RPI-1031 Is Rotated to the State Shown in Figure 3 (P3), the Lampshade Will Not Shadow; the Diode Will Light up, and the Two Phototriodes Can Receive Light, and Then All Will Light up, two GPIO Ports Output High Level.

5. When the RPI-1031 Is Rotated to the State Shown in Fig. 4 (P4), This State Is Unfavorable to the Description 4; the Output Levels of the Two GPIO Ports Will Be Connected.
