Abstract
Abstract This design with TMS320 series DSP and the new digital sensor DS18B20 as the core component temperature measurement and control system. The system USES TMS320 series TMS320LF2407 DSP as control chip, complete temperature receiving, conversion, display management; DALLAS produced by the new single serial digital temperature sensor DS18B20, complete temperature measurement and analysis capabilities. The whole system has the high level of integration, reliability and anti-interference is strong, extensible, available recognition serial number composition multi-point measurement, small volume, low power dissipation characteristics. This system has a temperature sensor, limit alarm and lower limit alarm, temperature control and display function, this paper introduces single line digital temperature sensor basic content of structure and main performance characteristics.
