Deployed: Week 2
05/14/2019 at 06:06 • 0 commentsFor 1 week, the device has been pinging back to the cloud with average humidity value as well as the battery values as recorded in the Google sheets.
The humidity values were pretty consistent from 87 RH% to 92 RH%.
The LiPo battery voltage levels came down steadily from a fully charged value of 4.2V to 3.9V.
I just put in the dehumidifier beside the device. So let's see whether the humidity levels change at all.

After a week, I will put in a dehumidifier to see whether the humidity levels are affected.

Mechanical considerations before designing the PCB
08/27/2017 at 22:56 • 0 comments- Place the PCB on top of the 2 AA battery holders
- Connect the battery wires on one of the shorter edge of the PCB
- Solder the ESP-12F on the other shorter edge of the PCB
- Bar LEDs are lining up on the longer edge of the PCB
- Place the ESP-12F module within the dimensions of the battery holder so that the final form can stand vertically as well
