摘要: The invention discloses a temperature detection circuit. circuit comprises unit comprising thermistor and fixed resistor which are in series connection, first controlled switch, second an amplification switch voltage unit, wherein one end of the is connected between resistor, other with made to realize closing when starts detection, variation amplitude detected be lower than preset threshold, disconnection, closing. Through circuit, precision improved resistance change not obvious, more uniform.
