Abstract: The term data logger (also sometimes referred to as a data recorder) is commonly used to describe a self-contained, standalone data acquisition system or device. These products are comprised of a number of analog and digital inputs that are monitored, and the results or conditions of these inputs is then stored on some type of local memory. In this paper, a Temperature Data Logging System is designed to record and display temperatures continuously. It uses a temperature sensor to sense the surrounding temperature and displays the temperature on the PC with the help of LPC 2148 ARM7 TDMI processor and the UART (Universal Asynchronous Receiver/Transmitter). The methodology for designing the temperature data logging system is discussed in detail. The code to implement the functionality of the logging system is modeled and simulated using the Software Tool Keilμ4. The characteristics of LM 35 temperature sensor and the hardware required to interface the output of LM 35 to the LPC 2148 is discussed in detail.
