9th LCSC Electronics Design Contest #Desktop Temperature and Humidity Monitor Type-C Charger 6925297A

Overview

The original project
used dry cell batteries as its energy source, but in this era dominated by new energy development, it's necessary to respond to the call of the times and abandon traditional dry cell batteries to reduce environmental pollution and lower battery costs.
Advantages include large

rechargeable
battery capacity,
long battery life,
and support for up to 5V 2A charging. Modifications
were made to address the issue of series connection causing charging failures. The battery power supply circuit was changed from series to parallel connection to achieve charging functionality.
A physical
monitoring device and charging demonstration video are provided.
