Assemble a battery to Capsule sensor


The capsule sensor is a global product, but because of international transportation, storage and other problems, default is no integrated battery inside the Capsule sensor.


After disassembling the sensor shell, you can see 2 pads on the round PCB at the bottom, and solder the battery positive and negative electrodes to this pad:



Battery specifications

In the capsule sensor, it’s already integrates a charge management circuit, but does not have an over-discharge protection circuit, so the lithium battery must have a protection circute. Battery must include following features:

  • Voltage: 3.7V

  • Charging voltage: 4.2V

  • Discharge cut-off voltage: ≤3.3V
