1. Equipment introduction:
Dual axis tilt sensor, using industrial grade MCU and low-power wireless transmission technology (NB IoT/LoRa), is a sensor product that collects object attitude angles at regular intervals. Equipped with a large capacity lithium battery and built-in solar charging, the sensor ensures long-term stable operation without worrying about power outage risks. The sensor reports data to the cloud server at regular intervals based on user set collection cycles, angle alarm thresholds, zero degree calibration, status heartbeat packets, and other functions. Users can remotely view the on-site facilities and equipment status of the sensor in a timely manner, achieving safe operation of large-scale engineering facilities and equipment, and playing a role in monitoring, early warning, and maintenance of various intelligent management functions. The sensor is designed based on industrial standards, with high precision, reliability, and stability.
2. Application direction:
It can be widely used in buildings, bridges, tunnels, large engineering equipment and other places.
3. Advantages and features of equipment:
1. Tilt sensor function:
(1) Support offline record storage function;
(2) Support sending from multiple servers;
(3) Support automatic updating of location information, with devices updating location information every 24 hours.
2. Timed collection function:
(1) After setting the collection cycle, the sensor counts according to the set cycle;
(2) After the timing cycle is full, the sensor starts to collect the tilt angle of the position, and after the collection is completed, it actively sends it to the server;
(3) After the sending is completed, the device enters sleep mode after a delayed reception waiting period (the user set reception waiting period, during which the service can issue instructions, ranging from 0 to 30 seconds, where 0 indicates no waiting for reception).
3. Tilt angle alarm function: can set sudden change alarm and over set alarm (alarm status can be manually or systematically cleared)
