Embedded low Cost Solution of Remotely Sensing Humidity


Objectives: To design a system capable of remotely measuring the Relative Humidity of the high voltage devices so that the risks involved with human physically interaction can be avoided, and the levels of humidity can be conveniently maintained at a remote location. Methods/Statistical Analysis: Variations in the humidity cause many major problems for human beings, electronic components, industrial machines etc. Hence to measure and maintain the humidity has become a nontrivial issue. However, in certain situations the manual methods of measuring humidity are not always convenient, in fact, hazardous. For instance, measuring and monitoring the humidity level of high voltage transformers can be very dangerous. The proposed system is the low cost and low complex implementation of embedded system and does not require Analog to Digital Conversion or vice versa to interface the Humidity sensing circuit with the microcontroller. The design provides the wireless transmission of the data, that makes easiness for the engineers (at industry) or for any other person (at home or any other place) to get humidity information of any remote and hazards locations. Findings: High power electrical devices such as transformers and transmission lines are severely affected by the humidity. Typically, the affordable levels of humidity are in the range of 45 to 65%. The rapid fluctuations in the levels of relative humidity can lead to a range of problems. The risks of physical damage, such as warping, cracking and splitting, chemical deterioration, and insect or mold attack are all increased when relative humidity is too high or too low. Also these fluctuations can damage collections that are experienced in many museums, galleries and libraries. Therefore, maintaining an appropriate level of humidity is imperative, as much as for hygienic reasons as well as for energy efficiency. Application / Improvement: The proposed design may find useful applications in Industries, agriculture fields, educational labs, Food storage places, Drying production industries, Blood banks, Coal mines, Sprinkler etc.
