The invention provides an intelligent fire sensing and control system. According to the intelligent fire sensing and control system, an intelligent home central control device is adopted, and on the basis, a temperature and humidity sensor, a smoke sensor, a formaldehyde CO sensor, a gas concentration sensor, an infrared sensor, a wireless signal transmitter, an intelligent switch and an intelligent remote control center and the like are further integrated. A mobile phone can be taken at any time and at any place, or a computer or a tablet computer is used for monitoring values of the temperature, the humidity, the heat sensation, the formaldehyde content, the CO content and the gas content in the room, and when any index in the room exceeds a preset numerical value, the intelligent remote control center and the intelligent switch controlled by the intelligent home controller can automatically start corresponding equipment.
