Note 1: Lithium batteries are not rechargeable,! Please replace the battery before full discharge. Do not try to charge it as there is a risk of explosion!

Note 2: Dormant working current means the product’s (including the internal LoRa module) working current, when it  is completely dormant without any wireless data sent or received. LoRa wireless CAD interception will be performed intermittently in the wireless module’s sleep state. By default, 32ms of wireless CAD interception will be performed in the factory state (listening state current is about 15mA). The factory inspection index of the product is the dormancy current without the LoRa module, typically 15uA, with a  maximum value of 26uA (the dormancy current is 3.9uA when LoRa module is dormant and there is no wireless data sent or received). The working current of the whole machine is guaranteed by design.

Note 3: The working temperature range is -20-60℃, limited by the working temperature range of the 3V(CR1220) button battery inside the product that supplies power to the RTC IC.

Note 4: Resolution refers to the minimum variation that can be detected by the sensor while working in its valid range.

Note 5: Accuracy refers to the difference between the real data and the data shown on the sensor.

Note 6: Zero temperature drift refers to the angle offset after a minor change over room temperature, where the fixed output angle is zero.

Note 7: Refresh time refers to the time used to renew the angle data in either axis.
