IoT (nesnelerin interneti) kavramı nesnelerin bir ağ üzerinden birebirleriyle haberleşmesi olarak tanımlanmaktadır. Nesnelerin interneti ile günümüzde farklı alanlarda birçok çalışma yapılmıştır. Giderek artan bir şekilde, farklı endüstrilerdeki kuruluşlar verimli çalışmayı arttırmak, daha kaliteli müşteri hizmeti sunmak, karar vermeyi geliştirmek ve işin değerini artırmak, müşterilerle iletişime geçebilmek için nesnelerin interneti teknolojisini kullanmaktadır. Yapılan bu çalışmada iş sağlığı ve güvenliği için IoT tabanlı bir cihaz geliştirilmiştir. Cihaz üzerinde iş güvenliğini, işçi sağlığını ve verimli çalışmayı etkileyen fiziksel koşullar göz önünde bulundurulmuştur. İş yeri için uygun fiziksel koşul parametreleri literatürde taranarak tespit edilmiştir. İş sağlığı için gerekli optimum fiziksel koşul parametreleri günümüzde yaygın olarak kullanılan arduino uno mikrodenetleyici geliştirme kartına kodlama aşamasında girilmiştir. Tasarlanan sistemde ısı ve nem sensörü, ldr ışık sensörü, manyetik alan sensörü, mq7 karbon monoksit gaz sensörü ve ses sensörü kullanılmıştır. Sistem üzerinde bulunan bu sensörler ile CNC dik işleme merkezinin ve freze cihazlarının sıklıkla kullanıldığı bir iş yerinde anlık ölçümler yapılmıştır. Cihaz 2 aylık bir süre ile iş yerinin fiziksel koşul paremetrelerini cihazda bulunan sensörler ile almıştır. Cihaz bu süre içerisinde 3051 veri almıştır. Yapılan bu ölçüm değerleri IoT gerçek zamanlı veri platformu olan thingspeak web sitesine esp8266 wifi modülü ile gönderilmiştir. Thingspeak web sitesine gönderilen veriler bu adreste grafik haline dönüştürülmüştür ve anlık olarak ölçüm sonuçları internet ortamından takip edilebilecektir. Bu sistem iş yerinde bulunacak ve iş sağlığı için gerekli fiziksel koşul verilerini sensörler aracılığıyla ölçüp esp8266 wifi modülü ile web sitesine gönderecektir. Eğer bu parametler optimum değerleri aşarsa sistem iş yerinde dışardan bağlanan bir alarm sayesinde işitsel uyarı verecektir. Ayrıca thingspeak web sitesindeki anlık parametreler android yazılım olan thingview sayesinde akıllı cihazlar ile de takip edilebilmektedir.
IoT (Internet of Objects) is defined as the communication of objects with each other through a network. The Internet of Things has been developed in many different areas today. More and more, organizations in different industries use the Internet of Things technology to enhance efficient work, provide better quality customer service, improve decision making and increase the value of the business, and communicate with customers. In this study, an IoT-based device was developed for work health and safety. The equipment has been taken into account the physical conditions affecting the safety of work, the health of workers and the efficient work. The appropriate physical conditions for the workplace are identified by scanning in literature. The optimum physical condition parameters required for work health have entered the coding stage of the arduino uno microcontroller development card that is widely used today. The designed system has used heat and moisture sensor, ldr light sensor, magnetic field sensor, mq7 carbon monoxide gas sensor and sound sensor. These sensors on the system and instant measurements have been made in a workplace where CNC straight processing center and freeze devices are often used. The device received the physical condition parametrs of the workplace for a period of 2 months with the sensors on the device. The device has received 3051 data during this time. These measurement values were sent to the thingspeak website, the IoT real-time data platform, using the esp8266 wifi module. The data sent to the Thingspeak website is converted into graphics on this address and the measurement results can be followed instantly from the internet environment. This system will be in the workplace and measure the physical condition data necessary for work health through sensors and send to the website with the esp8266 wifi module. If these parameters exceed the optimal values, the system will give a hearing warning thanks to an alarm connected from outside at the workplace. Also instant parameters on the thingspeak website can be traced through smart devices thanks to the android software thingview.
The concept of IoT (Internet of Things) is defined as the communication of objects with each other over a network. With the Internet of Things, many studies have been done in different fields today. Increasingly, organizations in different industries are using the Internet of Things technology to increase efficient work, provide higher quality customer service, improve decision making, and increase the value of the business and communicate with customers. In this study, an IoT based device was developed for occupational health and safety. Physical conditions affecting occupational safety, worker health and efficient work have been taken into consideration. The physical condition parameters suitable for the workplace were determined by scanning in the literature. The optimum physical condition parameters required for occupational health were entered into the arduino uno microcontroller development board, which is widely used today, at the coding stage. The designed system used heat and humidity sensor, ldr light sensor, magnetic field sensor, mq7 carbon monoxide gas sensor and sound sensor. With these sensors on the system, instant measurements were made in a workplace where CNC vertical machining center and milling devices are frequently used. The device received the physical condition parameters of the workplace with sensors located in the device for a period of 2 months. The device received 3051 data during this time. These measured values were sent to the thingspeak website, IoT real-time data platform, with the esp8266 wifi module. The data sent to the Thingspeak website has been converted into a graphic at this address and measurement results will be instantly tracked on the internet. This system will be present in the workplace and will measure the physical condition data required for occupational health through sensors and send it to the website with the esp8266 wifi module. If these parameters exceed the optimum values, the system will give an audible warning through an alarm connected externally at the workplace. In addition, instant parameters on the thingspeak website can be monitored with smart devices thanks to the Android software thingview.
