Title:
TEMPERATURE DETECTION DEVICE, TEMPERATURE DETECTION METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/085045
Kind Code:
A1
Abstract:
In this temperature detection device, a regulator applies a constant voltage to a series circuit that includes a temperature resistor and a variable resistor. The temperature resistor and the variable resistor divide the constant voltage. The resistance value of the temperature resistor changes in accordance with the temperature of the temperature resistor. A microcomputer adjusts the resistance value of the variable resistor in accordance with the resistance value of the temperature resistor. After adjusting the resistance value of the variable resistor, the microcomputer converts, into a digital value, the divided voltage divided by the temperature resistor and the variable resistor, and determines the temperature of the temperature resistor on the basis of the digital value thus converted.
