Thermal resistance temperature circuit system design and research based on the constant current source driver
RTD temperature measurement system for measuring lead resistance errors brought insurmountable problem by using a constant current source drives the thermal resistance and by adding and subtracting circuit to overcome the measurement error caused by wire, which has won high precision analog signal. After AD conversion of the analog signal by returning timed sampling filter out interference and using STM32 so as to obtain a high accuracy temperature values.
