Note 1: Lithium ion batteries should never be recharged, otherwise they may explode. When a battery is out of power,
please replace it in time, do not charge it!
Note 2: The self-discharge rate of the battery is less than 3% a year, if it is stocked at room temperature (25°C). The
self-discharge rate becomes higher if the battery is stocked at a higher temperature.

Note 1: Resolution refers to the minimum variation that can be detected by the sensor while working in its valid range.
Note 2: Heartbeat interval refers to the time interval at which the device periodically uploads data to the server.
Note 3: Alarm accuracy refers to the angular error when the product triggers an alarm. Suppose the alarm angle is 3 degree and the alarm accuracy is 0.03 degree, if X and Y axis angle are smaller than 2.97 degree, alarm will not be triggered, if X or Y axis angle is between 2.97 and 3.03 degree, alarm may or may not be triggered, if X or Y axis angle is larger than 3.03 degree, the alarm will be triggered for sure.
Note 4: Alarm delay time refers to the time when the device continues to tilt beyond the alarm angle to trigger an alarm.
Note 5: Estimation is based on such conditions: at an ambient temperature of 25°C, the capacity of the battery is 19,000mAh, the battery loss factor is 0.7, and the heartbeat rate is 24 hours. Average current for transmitting data ≈ 31mA, time for single transmission ≈ 22s, battery working time = 19000*0.7/24/365/ ((0.22*(24-22/3600)+31*22/3600)/24) ≈ 6 years.
