description The invention provides a gas detector, an identification method of a sensor thereof, and a sensor connection detection method. The detector comprises a main circuit board, a sensor and a sampling circuit board forming one-to-one correspondence with the sensor. One sampling resistor and two sampling contacts are arranged on the sampling circuit board. The main circuit board is provided with a voltage dividing resistor, two contacts, a microprocessor circuit, and a voltage acquiring circuit, wherein voltage acquiring terminals of the voltage acquiring circuit are respectively connected to the two contacts, and the voltage acquiring circuit board is connected to the microprocessor circuit. With the connection of the contacts, the voltage dividing resistor and the sampling resistor form a sampling circuit. The identification method and the connection detection method comprise steps that: according to the voltage values acquired by the voltage acquiring circuit board, the microprocessor circuit board searches pre-
