In this paper, an Arduino-based real time wireless temperature measurement and logger system is presented. Wireless transmission of the temperature data occurs via a Bluetooth link. An experimental setup to achieve reliable output was prepared using LM35 temperature sensor. The real time temperature information obtained was observed at MATLAB® Graphical User Interface and at mobile phones via a basic hybrid mobile application (Android, Windows, ios) designed by us. Experimental result and percentage error curve endorse the reliability and feasibility of the proposed system. Moreover, a Global System of Mobile (GSM) module is also used for sending alert messages to a pre-assigned mobile number when an alarm condition is achieved. © 2017 IEEE.
