Avaliação de sensores de temperatura infravermelha em mudas de cedro-rosa (Cedrela fissilis)

Abstract

With the stimulus to facilitate the access of small farmers to equipment that help reduce water waste, determination methods of water stress plants has been proposed and developed. In recent years, many microcontroller systems gained ground in the development of new products, these platforms provide a complete environment for the implementation and monitoring through specific sensors, in this context, this paper aims to use the Arduino embedded system to compare efficiency of a dedicated platform infrared temperature sensor in relation to a conventional sensor. Data processing was carried out in Sisvar program which was conducted normal Shapiro - Wilk test and the mean t Student test group. The results showed that the sensors can be considered equal with closely similar average readings, verifying that the MLX90614 Arduino platform sensor can be used in reading vegetable temperatures sheet, and has a lower cost than the commercial infrared digital thermometer.
