Mobile Platform Thermal Sensor Application Based on IoT and Socket Programming

Abstract

With the increase in IoT-based applications in recent years, technological developments and achievements in microelectronics have led to the development of sensor-based systems. A high degree of accuracy is achieved with the help of these systems, which will reduce the costs of health services and have a positive impact on the health sector people. However, with the spread of the Covid-19 epidemic worldwide, low-cost temperature measurement has gained importance. In this article, a study was carried out to detect living things using a thermal sensor on a mobile platform. It is planned to add a thermal camera feature to the thermal sensor to make the detection. Since the objects in the sensor's field of view can be noticed due to the heat they emit, the movements of the objects can be easily followed. The mobile platform connection of the thermopile sensor is provided with the I2C protocol. In the study, a server was created on the mobile platform, and communication was carried out with TCP socket programming technology in the Python programming language. TCP client performs real-time data acquisition from the sensor. In addition to these, a desktop application has been designed to display the data in a way that users can understand. The application processed the data with 64 float data arrays, and a heat map image was obtained. In addition, the accuracy of the study was tested by conducting trials under different environments and temperatures from various people. Finally, the accuracy of the heat map of human and living objects has been demonstrated by matching the thermal image and the camera image in the study.

Mobil Platformda IoT Temelli ve Soket Programlamaya Dayalı Termal Sensör Uygulaması

Abstract

Son yıllarda IoT temelli uygulamaların artması ile teknolojik gelişmeler ve mikroelektroniksel alandaki başarımlar, sensör tabanlı sistemlerin gelişmesine yol açmıştır. Temelde sağlık hizmetlerinin maliyetlerini düşürmek ve insanlara sağlık sektörü üzerinde olumlu bir etki gösterecek olan bu sistemlerin yardımı ile yüksek bir derecede doğru sonuçlar elde edilmektedir. Bununla birlikte, dünya çapında Covid-19 salgınının yayılmasıyla da düşük maliyetli olarak sıcaklık ölçümü önem kazanmıştır. Bu makalede mobil platform üzerinde termal sensör kullanılarak canlı varlık tespiti yapılmasına yönelik bir çalışma gerçekleştirilmiştir. Temelde tespitin yapılabilmesi için termal sensöre bir çeşit termal kamera özelliği kazandırılması planlanmıştır. Sensörün görüş alanındaki cisimler yaydıkları sıcaklık nedeniyle fark edilebildiğinden dolayı cisimlerin hareketleri kolayca takip edilebilecektir. Termopil sensörün mobil platform bağlantısı I2C protokolüyle sağlanmıştır. Çalışmada, mobil platform üzerinde bir sunucu oluşturulmuş ve Python programlama dilinde TCP soket programlama teknolojisi ile haberleşme gerçekleştirilmiştir. TCP istemcisi sensörden gerçek zamanlı veri alınması işlemini gerçekleştirmektedir. Bunlara ek olarak, verilerin kullanıcıların anlayabileceği şekilde görüntülenebilmesi için bir masaüstü uygulaması tasarlanmıştır. Uygulamada veriler alınan 64 adet float veri dizisi ile işlenerek ısı haritası görüntüsü elde edilmiştir. Bununla beraber, çeşitli kişilerden farklı ortam ve sıcaklıklar altında denemeler yapılarak çalışmanın doğruluğu test edilmiştir. Son olarak, yapılan çalışmada termal görüntü ile kamera görüntüsü eşleştirilerek insan ve canlı nesnelerin ısı haritası gösterilmiştir.
