Production based on ATMega8L-8PU temperature and humidity meter

RF cable can be customized for other specifications

Summary: I made a calendar clock, and now expand on the basis of the calendar clock: let it have the function of detecting the temperature and humidity of the atmosphere, running 24 hours a day without interruption and timing detection, so the calendar clock turns into a small Temperature and humidity meter. Although there are many meteorological elements, the temperature and humidity we use most often. One is the degree of heat and cold, and the other is the amount of water vapor in the ambient air. General household thermometers are very common, and there are few hygrometers. There used to be a dry and wet bulb thermometer, but it is more troublesome to use and the accuracy is not high. Now with the application of electronic technology, we can make a small instrument that can display temperature, humidity and time at the same time, and put it at home to monitor our small environment at any time.
