Rok Ivančič (2017) Sensor module for cold chain monitoring. EngD thesis.
Abstract
Internet of things appears in many fields where it's important that devices communicate to each other and are connected to the Internet. The main purpose of its use is to simplify various tasks in the industrial and home use. The diploma thesis presents a solution for monitoring and analyzing a cold chain with sensor system to capture and review collected data. Two microcontrollers, Arduino and Raspberry Pi are used, which are currently the most popular. In fact, these are two small computers that construct the prototype of the realized sensor system. Arduino has connected sensors for temperature, humidity and flammable gases and provides carrying out measurements during the system operation and collects data. By using radio-frequency transmitter and receiver it sends them to Raspberry Pi which receives data and using a simple application displays or sends them to selected e-mail address. Sensor system enables monitoring of the state of the atmosphere (temperature, humidity, gases) in the room or outdoors where testing has also taken place. On graphs it is also presented monitoring of temperature and humidity in various weather conditions and detection of gas (CO2).
