If you have a sensor that outputs a reading like a DHT22/DHT11 sensor then it would be a good idea to store it somewhere for historical purposes. Imagine if you would like to know the average, the peak, or the mean of the temperature and humidity readings in a day or even weeks or...
Thus, a data analysis was applied upon variables of temperature and relative humidity for heating zones, trying to know how much energy supplied by source was used, as well as, voltage and current variables are measured in the same moment that temperature and relative humidity are acquired. ...
T=data*(5/1024)*(1000/10)// T 为温度值, data为analogRead读到的值// (5 / 1024) 是模拟值的精度,单位伏特 V// (1000 / 10)是单位换算,将伏特转化为毫伏 mv 代码来源:http://www.circuitstoday.com/temperature-logger-using-arduino* 硬件插线、软件调试完毕之后,就可以通过Arduino IDE里面的串口...

Its ability to measure humidity and temperature with precision makes it a valuable tool for data loggers, testing and inspection equipment, and consumer goods. The sensor's ultra-long signal transmission distance of up to 20 meters makes it suitable for even the most demanding applications, ...
SDFile.println(Temperature); SDFile.close(); } /* Wait a second before reading again */ delay(1000); } [/cpp] Insert an SD card into the data logger shield and upload the sketch to your Arduino. Open the serial monitor window in your Arduino IDE by going to Tools->Serial Monitor....
