NETVOX Wireless Sensor R718DA is a ball-type vibration sensor of Netvox ClassA type equipment based on LoRaWAN open protocol. The sensor is attached to the detected device with magnet. When the device vibrates, the sensor is triggered. R718DA immediately sends the trigger information to the gateway. R718DA is compatible with LoRaWAN protocol.

Principle of Operation

When the vibration sensor is tilted and the tilting angle is greater than 10 degrees, it will be OFF mode. When the tilt level changes, and the triggering end is lower than tilt angle 10 degrees, it will be ON state. The module can detect open circuit OFF state and closed circuit ON state signal to detect vibration or move.

Example Applications

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

Rolling Ball Vibration Sensor

Vibration Sensor Case Size	L:43mmW:13mmH:12mm
Vibration Sensor Maximum Voltage	5V
Sensor Switch Life	Up to 100,000 times
Vibration Sensor Sensitivity	When placed horizontally, any shaking can trigger the device. When the pilot electrical end (without foot end) is placed downward, it is not easily to be triggered.
Vibration Sensor Characteristic ( Dual ball type single direction tilt sensitive trigger sensor)	When the vibration sensor is tilted and the tilting angle is greater than 10 degrees, it will be OFF mode. When the tilt level changes, and the triggering end is lower than tilt angle 10 degrees, it will be ON state. The module can detect open circuit OFF state and closed circuit ON state signal to detect vibration or move.
External Cable Length	1 meter
