ITEM NAME:Tilt Sensor Module SW520D Angle Tilt Detection Board with Roll Ball Switch Descriptio n Description: Module instructions: 1. Please refer to the wiring diagram below for detailed instructions for the wiring of this module. 2. The switch output of the module depends on the on-off and on-off of the Angle switch. When the Angle switch is off, DO outputs high level, while when the Angle switch is on-off, DO outputs low level. 3. The output end can be directly connected with the microcontroller to detect high and low level through the microcontroller, so as to detect the Angle change; 4. The output end can directly drive the relay module, which can form a high-power Angle switch to protect the function of automatic power off when the electrical equipment and other products are dumped. USES: All kinds of products tilt, tipping trigger alarm, dumping power sensor, tilt sensor. Specifications: 1. High sensitive Angle switch SW-520D is adopted as the sensor. 2, Comparator output, signal clean, good waveform, strong driving capacity, more than 15mA. 3. Operating voltage: 3.3v-5v 4. Output form: digital switch output (0 and 1) 5. Fixed bolt holes are provided for easy installation 6. PCB size of small board: 3.2cm x 1.4cm 7. Use wide voltage LM393 comparator Package Included: 1 *Â Angle Sensor Module Note: 1.Due to the manual measurement and different measurement methods, the actual size could be slightly different. 2.Please be reminded that due to lighting effects and monitor's brightness/contrast settings etc, the color tone of the website's photo and the actual item could be slightly different. Whatever the ending's perfect or not, you can't disappear from my world Tilt Sensor Module SW520D Angle Tilt Detection Board with Roll Ball Switch.USES: All kinds of products tilt, tipping trigger alarm, dumping power sensor, tilt sensor. The switch output of the module depends on the on-off and on-off of the Angle switch. When the Angle switch is off, DO outputs high level, while when the Angle switch is on-off, DO outputs low level.
