Digital Thermometer Circuit – Uses a Solar Cell for Power

Last Updated on June 9, 2020 by Swagatam Leave a Comment

light thermometer 1

The articles explains a digital thermometer circuit project that works without a battery. Instead of a battery the circuit utilizes a small solar cell and operates by deriving power from the ambient light available from the surrounding light sources. This allows the circuit to be extremely compact, light weight, versatile and hassle free while measuring […]
