Abstract: All laboratories needs temperature measurement and monitoring system. Instead of noting down every reading using an analog device, the implementation of digital data logging is a better and in-situ way. The temperature data is read from the sensor and it is been logged into an Excel file. In our lab this setup provides very good alternative for existing analog thermometers. The Raspberry Pi Temperature sensor kit provides low cost, and consistent temperature measuring solution.
We implemented our experimental setup with the help of following components
Key Words: Raspberry Pi, Temperature Logger, Low cost Temperature measuring system, Linux, Python, Ubuntu
1.INTRODUCTION Measurement of temperature is existing from development of thermometers. Output of the thermometer is shown usually by calibrated reading marks. For laboratory level an issue is raised. In an experiment if we ought to measure the temperatures for a long period of time, the difficulty to record is raised. The temperature needs to be noted in every period of time, also the system is to be monitored for this entire period. Hence it is decided to construct a temperature logger as an alternative for existing setups. The aim of this study is to constructed a Temperature logger that is low cost, versatile, and that has consistent performance efficiency. In this paper we discussed about constructing temperature logger with Raspberry Pi. The Raspberry Pi models are capable of performing general-purpose computing and for that reason they are most favourite candidates for introducing learners to general computing and computer programming [1]. Ping, L et al.,[ 2] explained about the temperature test system designed by DS18B20. Shinde, P. A et al.,[3] discussed about implementation of DS18B20 in vehicle monitoring system using Raspberry Pi. Raspberry Pi can be used as an integrated system for any purpose of measurement [4, 5]. For this project we used Raspberry Pi 2 Model B[6], and DS18B20. For coding purposes we used Python programming language.

3. Experimental setup A setup for measuring temperature is constructed using Raspberry pi. We have booted raspberry pi with Noobs [7] which contain Raspbian Jessie with Pixel[8] operating system. A constant voltage is supplied to the micro USB port. The monitor is powered with external power supply. We are now able to access the entire system within this graphical user interface. We prefer to work in terminal. With in the terminal itself we can control the entire system ,also with the super user privileges. Super user access is gained with “sudo” comment[9]. With “sudo raspi-config” comment we enabled ssh[10] and I2C console. These changes came into action once the system was rebooted. After the reboot an update is needed. We used aptitude package manager. Its the front end for the Advanced Packaging Tool (APT)[11]. The apt-get update, also apt-get upgrade comments were executed with sudo .
