Microprocessor temperature control device for a thermal object
Admiral Makarov State University of Maritime and Inland Shipping, St. Petersburg 198035, Russian Federation
The article deals with a device for temperature control of a thermal object. The device is based on a single-chip AVR ATmega32 microcontroller. There are two modes of temperature regulation. The first is designed for temperature regulation within the range of -55 ° C to +125 ° C, and the second is from +126 ° C to +1000 ° C. The first range uses a DS18B20 digital serial output temperature sensor. The temperature measurement resolution in the first temperature range of -55 °C to +125 °C is 0.0625 °C. The second range uses a K-type thermocouple and a MAX6675 thermocouple signal converter with I2C interface. The discreteness of temperature measurement in the range from +126 C to +1000 C is 2 C. The microprocessor based controller has a very wide temperature control range from -55 to +1000°C, which is well within the temperature range required by the process. In the first area, due to high accuracy digital temperature sensor DS18B20, the resolution is very good ±0.0625 °C, which enables the use of the controller in climate control systems.
