A platinum resistance thermometer consists of a platinum element, whose resistance depends on temperature. The commercially available platinum elements are PT100 and PT1000. Nominal resistance at 0°C is 100 Ω for PT100 and 1 kΩ for PT1000. The temperature coefficients for platinum are $ A = 3.91 \times 10^{−3} $ linear and $ B = -0.588 \times 10^{−6} quadratic.

PT1000 can be directly connected between SEN and Ground to measure the resistance. The following Python program can be used
