Process variables (like temperature, pressure, flow, level) vary with time in certain applications and this variation should be recorded so that a control action can take place at a defined set point. This paper proposes an 8-bit embedded controller interfaced with a temperature sensor through Analog to Digital convertor. This portable data logger is programmed to control and log the temperature variations. The temperature is displayed on a liquid crystal display (LCD) interfaced with the 8-bit embedded controller and is wirelessly transmitted to a PC communication port or a PDA communication port through Infrared/Bluetooth link.

Using the proposed scheme, the number of codes searched before finding suitable vacant code is least. Also the external code fragmentation which can lead to code blocking is less because of the compact nature of code assignment scheme. Simulation results are presented to compare the reduction in call blocking probability of the proposed scheme with the existing novel assignment schemes.
