As the world is developing at a fast pace, every technology must improve to meet the higher standard of human needs and be convenient to users. In the past, sensors and programming devices are physically connected to laptop, desktops or work stations to read/write data and upload/download the programming codes. The problem arises when there is a need for users to make changes to the program, user must be physically at the location of the programming devices and connect it to laptop before making any changes. It is very inconvenient for users especially if the programming devices are installed at inaccessible areas. It is also very cumbersome for the users to visit each sensor stations to make minor programming modifications, if the different sensors and programming devices are located throughout the buildings or production plants. This project aims to design and build the portable sensor station which is low-power, light-weight and log sensor data for users. This portable sensor will measure temperature and humidity from surrounding and hence, it is also known as, IEQMS, Indoor Environmental Quality Monitoring Station. This sensor station will be connected wirelessly to the server and will send data wirelessly as well. By using this portable IEQMS station, users can make changes to program and monitor data remotely via wireless network.Bachelor of Engineerin
