1, the use of highly sensitive angle switch SW-520D as a sensor.
2, the comparator output signal clean, good waveform, driving ability, than 15mA.
3, the working voltage 3.3V-5V
4, the output format: Digital switching output (0 and 1)
5, a fixed bolt hole for easy installation
6, small PCB board size: 3.2cm x 1.4cm
7, using a wide voltage comparator LM393
1, the wiring of the module wiring diagram see below, there is a detailed description;
2, the switch module outputs depends on the conduction angle switch on and off, when the angle switch off, DO output high, angle switch is turned on, DO output low;
3, the output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the angle change;
4 relay outputs can directly drive module, which can be composed of a high-power switching angle, protection of electrical equipment and other products dumped automatic power-off function.
1x SW-520D tilt angle sensor module
