7. Use wide voltage LM393 comparator
Module instructions:
SW-520D
1.The switch quantity output by the module depends on the turning on and off of the angle switch. When the angle switch is turned off, the DO outputs a high level, and when the angle switch is turned on, the DO outputs a low level.
2. The output end can be directly connected with the single chip microcomputer, and the high and low levels are detected by the single chip microcomputer, thereby detecting the angle change.
3. The output terminal can directly drive the relay module, which can form a high-power angle switch to protect the electrical equipment and other products when the power is automatically turned off.
SW1801P
1. When the product does not vibrate, the vibration switch is off, the output end outputs a high level ,and the green indicator light is off.
2. When the product vibrates, the vibration switch i s turned on instantaneously, the output end out puts a low level, and the green indicator light is on.
3. The output terminal can be directly connected with the single chip microcomputer, and the high and low levels are detected by the single chip microcomputer, thereby detecting whether there is vibration in the environment and playing an alarm role.
Module wiring instructions:
1. VCC: Connect to the positive pole of the power supply.
2. GND: Connect to the negative pole of the power supply.
3. DO: digital signal output
4. AO: This function is invalid with this vibration sensor.
Note: The polarity of the power supply cannot be r versed. Otherwise, the chip may be burned out. When the switch signal indicator is on, it outputs low level , not bright and outputs high level. The output level of the input signal is close to the power suppl y voltage.
Package included:
1 x SW-1801P vibration sensor/SW-520D Tilt Sensor Module(optional)
