Digital Thermometer Design Based on Single-Chip AT89C2051

Abstract:

Single-chip AT89C2051 as the main-control component of the device, we designed a digital thermometer from the aspects of hardware, it with the aid of temperature sensor DS18B20, the device used single bus technology to detect the ambient temperature (analogue) is converted into digital quantity, it was accepted, processed, judged by single-chip microcomputerand then control and display. The temperature measured range in - 30 °C to + 120 °C, the accuracy class + 0.5 °C, four LED Nixie tube as display mode.
