I am going to measure the temperature using low cost and efficient lm35 analog output temperature sensor with arduino. kT (also written as kBT) is the product of the Boltzmann constant, k (or kB ), and the temperature, T. This product is used in physics as a scale factor for energy values in molecular -scale systems (sometimes it is used as a unit of energy), as the rates and frequencies of many processes and phenomena depend not on their energy alone, but on the ratio of that energy and kT, that is, on E / … Other common values are 298 K (25 C or 77 F) and 293 K (20 C or 68 F). the normal temperature of a living room, usually taken as being around 20°C. It relates to the state of a persons mind, whether you feel too hot or too cold. This range is recognized as the average comfort zone for humans. The value of the temperature is obtained by this equation: Temperature (˚C) = Analog Voltage (V) * 100 After recording the first temperature reading, the current, last recorded, minimum, and maximum temperatures are also set. Room Temperature Definition. People tend to accept a slightly higher room temperature in the summer and lower value in the winter, based on the clothing they would wear outdoors. There are many factors that affect normal room temperature, such as: Environmental factors: such as the air humidity and the sources of heat affecting the ambient room temperature Helmenstine, Anne Marie, Ph.D. "Room Temperature Definition."
