Humidity and Temperature LCD Display with Power Saving Mode: Minimal parts, Quick, Inexpensive, and Practical

Since my study was not always at the best temperature, I decided it would be useful to display the ambient temperature on my desk. The cost of a sensor that provided humidity, in addition to temperature, was not prohibitive; therefore a display of humidity as well as temperature was included in this project. Both the DHT11 and DHT22 sensors I considered provide temperature results in Centigrade. Fortunately it is an easy conversion to Fahrenheit (the format used in the USA, which is my location) . The sketch below displays temperature in both Fahrenheit and Centigrade, so it is applicable to whatever region of the world you are located in. My initial project only involved temperature measurement, but since adding humidity was not too costly, I decided to include it in this project.”
