Fire early warning equipment and system

The utility model discloses a fire hazard early warning device and system, applied to the security defense technology field, the fire hazard early warning device comprises a cloud chamber, a processor and a sampling pipe, the side wall of the sampling pipe is provided with a plurality of sampling holes, the first end of the sampling pipe is connected with the cloud chamber, the cloud chamber is connected with the processor, the sampling pipe is used for being arranged at a position to be detected, and the processor is used for being connected with the processor. External air is transmitted to the cloud chamber through the sampling hole; the cloud chamber is used for determining the number of the pyroelectric ions in the air in the cloud chamber; the processor is used for giving an alarm prompt under the condition that the quantity of the pyroelectric ions is greater than a threshold value; therefore, early warning of the fire hazard is realized before the fire hazard occurs, the detection sensitivity is high,
