Embodiment 1

[0036] The second detection feedback circuit is used to monitor the temperature of the smoke sensor in real time, and to perform feedback control on the working voltage or current of the smoke sensor, and the second detection feedback circuit is connected to the smoke sensor. The second detection feedback circuit includes a field effect transistor Q2, a thermistor RT2, a resistor R2 and a control circuit. The control pole of the field effect transistor Q1 is connected to the resistor R2 and the thermistor RT2 respectively, and the drain of the field effect transistor Q2 is grounded. The source of the field effect transistor Q2 is connected to the control circuit, the control electrode of the field effect transistor Q2 is connected to the common end of the resistor R2 and the thermistor RT2, the other end of the thermistor RT2 is grounded, and the other end of the resistor R2 is connected to the power supply V2. That is to set the thermistor RT1 near the detected smoke sensor to...
