Abstract

There are a lot of kinds of the thermometry apparatus. Relatively cheap, high speed, simple and easy measuring equipment are used. We often get different thermal environmental elements value. When we measured on the same environment condition because temperature and heat radiation are equal in testing chamber, we can measure high precision. At the time of everyday life, in an air conditioner under the summer heat environment and a heater at the time of the chilliness and under the heterogeneous heat radiation environment, heat radiation and temperature are not equal. It is necessary to check emission environment particularly then. In spring and the autumn season, there is much top and bottom difference of temperature. Even with a low-power LED lamp, lighting fixtures generate heat. When we measure temperature, there are methods to reduce the heat radiation that a sensor receives and to gain convection heat transfer. This report is a method to insert a temperature measurement sensor in a ventilation pipe. The sensor which we used just made it the one which could conjugate. We examined battery, the fan motor and digital relative humidity sensors to lengthen use time. We want to describe the production of a tool measuring temperature, the humidity, the heat radiation income, expenditure and water evaporation quantity from the surface in the narrow district such as a wall, clothes and the bedding.
