Temp sensor provides thousandth of a degree precision

Keywords:temperature sensor? precision temperature? microprocessor?

Cambridge Temperature Concepts has designed a wireless temperature sensor that can measure body temperature to within a thousandth of a degree, while current solutions typically have precision of a tenth of a degree.

The coin-sized unit also uses power-saving techniques to extend the battery life to in excess of six months rather than the usual life of a few days. The sensor's precision and long life open up many new applications in the medical field, and the company has already used it to create a device called DuoFertility to assist women in getting pregnant.

The sensor uses a Microchip PIC 8bit microprocessor to process and compress the temperature readings, which are taken every few seconds. Up to a month of data can be stored on the on-board 2Mbyte memory, which is downloaded via RF by a reader when required. Average sensor power consumption is less than 1?A, providing for months of continuous use off a tiny battery.
