Currently we are in a time where all equipment have to be tested for different circumstances. For example, if you take a laptop the extreme conditions in which it functions properly need to be known. These extreme conditions could be high temperature and humidity or low temperature and humidity. To test any equipment like a phone, a laptop or any device, a temperature and humidity chamber is needed.
In this thesis the communication between a control box and a main PC was studied. All the command bits sent from both directions were well documented. This communication happened through a RS-232 DB-9 cable and had its own communication protocols. In addition, a remote system in which the operator could monitor the chamber remotely was essential, hence, this thesis covers two software applications in which one reads the temperature and humidity values which are exchanged between the main PC and the control box and displays those values in a graph. The other one is for the outside sensor, DS18B20, which is connected to the GPIO's of the Raspberry Pi and records the values in to a database and displays those values using a web page.
This experiment was done by using a Temperature and Humidity Chamber (EUT), RS-232 cable, Raspberry Pi, a DS18B20 temperature sensor and also by using the Linux operating system.
