NETVOX Wireless Sensor R718DB is a LoRaWan Spring type Vibration sensor and can detect the vibration or movement signal, and transmit the detected data to other devices through the wireless network.

Principle of Operation

When the shock sensor is touched by an external force to reach the corresponding vibration force or the moving speed reaches an appropriate centrifugal force, the module can detect the vibration signal or the movement signal.

Example Applications

Animal Trap Monitoring
Vibration Monitoring
Vibration Metering
Objects to be detected vibration or movement

Animal trap

Spring Vibration Sensor

Vibration Sensor Case Size	L:43mmW:13mmH:12mm
Vibration Sensor Maximum Voltage	5V
Sensor Switch Life	Up to 200,000 times
Vibration Sensor Working Principle	When it is at rest, it is in the open state OFF state. When the external force is touched to reach the corresponding vibration force, or when the moving speed reaches the appropriate centrifugal force, the conductive pin will instantly reach the ON state. When the external force disappears, the switch returns to the OFF state.
