Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

In one aspect of the present invention, there is provided a smoke sensor, comprising: the smoke alarm device comprises a smoke sensor S1, a smoke alarm chip U10, a buzzer BZ2 and a ZIGBEE wireless module U11, wherein the output end of the smoke sensor S1 is connected with the acquisition input pin of the smoke alarm chip U10, the oscillation waveform signal output pin of the smoke alarm chip U10 is connected with the buzzer BZ2, and the alarm signal output pin of the smoke alarm chip U10 is connected with the input pin of the ZIGBEE wireless module U11.

Preferably, the smoke alarm chip U10 is SDH 3810. Preferably, the ZIGBEE wireless module U11 is FNB 5616.

The smoke alarm chip U10 is a smoke alarm installation special IC, when smoke is detected by the smoke sensor S1, signals are input to pins 1 and 2 of the smoke alarm chip U10, meanwhile, oscillation waveforms are output by pins 8 and 9 of the smoke alarm chip U10, and a buzzer BZ2 alarm sound is output. Meanwhile, the 7 feet of the smoke alarm chip U10 send alarm signals to the ZIGBEE wireless module U11, and the ZIGBEE wireless module U11 sends the alarm signals to the handheld terminal equipment, so that the aim of remote monitoring is fulfilled.

The utility model discloses be applied to the smog concentration in intelligent household equipment with all-weather detection place, reach 100ppm product and will report to the police when smog gas concentration, can install it in house or office, places such as mill carry out remote monitoring to know this local smog gas situation, discover smog early, retrieve the loss, still accessible gateway connection is to handheld terminal, thereby reaches the smog condition in remote monitoring will monitor the place, its low cost.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
