NETVOX LoRaWanWireless Activity Event Counter is a device detects the number of movements or vibrations (such as detecting the motor a few times a day), the maximum number of movements or vibrations can reach 2^32 times (theoretical value), and sends the information of the number of movements or vibrations to the gateway for processing. Apply SX1276 wireless communication module.

R311FB vibration alarm: The device detects sudden movement or vibration, and the quiescent state changes. The device waits for a certain period of time (DeactiveTime) to enter the quiescent state and counts 1 time for the cumulative number, sends a report of the cumulative number of vibrations, and restarts the preparation for the next detection. If the vibration continues to occur, the timing of DeactiveTime restarts until it reaches a standstill to count 1 time for the cumulative number. The count data is not saved when it is powered off.
