Designing of wireless mobile data loggers

Data logging and recording is a common measurement application. It involves the phenomenon of measuring and recording parameters having versatile application. Data loggers in particular, are sophisticated electronic devices that record data over a period of time with respect to external sensors and transducer inputs. They are generally based on modern day microprocessors or microcontrollers and are conventionally small, independently powered and provided with substantial memory storage and their most important component, i.e. the specific transducer. here the approach is to establish a wireless link between the mobile robot developed on an 8-bit embedded platform capable of navigation and a remote central command unit using wireless UART, thus allowing real- time monitoring and measurement of temperature. The wireless link is established using the 2.4GHz CC2500 Radio frequency Module developed by Texas Instruments. The module has a typically good range and has a very robust communication protocol. The entire setup was mounted on a 4 wheeled robot which was also controlled using the CC2500 module.
