Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment:

Indoor air environment monitor as shown in Figure 1, the indoor air environment monitor is by cabinet 9, be arranged on the keyboard 4 on the cabinet 9, the power supply changeover device 10 that is connected with cabinet is formed, it is provided with air mass sensor 1 in cabinet 9, wave filter 2, central processing unit 3 and hummer 5, cabinet 9 is provided with alarm lamp and power light 7, air mass sensor 1 is connected with central processing unit 3 by wave filter 2, the output terminal of central processing unit 3 connects hummer 5 respectively, red alarm lamp 8 and yellow alarm lamp 6 and power light 7, keyboard 4 is connected with central processing unit 3, and power supply changeover device 10 is powered to the indoor air environment monitor by central processing unit 3.

Described air mass sensor 1 by described environmental chemistry parameter sensors be a kind of in cigarette particle sensor, carbon dioxide sensor, formaldehyde sensor, benzene sensor, toluene sensor, alcohol sensor, carbon monoxide transducer, ammonia gas sensor, the pellet sensor or arbitrarily several and described environmental physical parameter sensor be a kind of or any several composition in temperature sensor, relative humidity sensor, the baroceptor, and be installed in the box body 8.

As shown in Figure 2, described wave filter 2 is made up of resistance R 1, potentiometer Rp and Sheffer stroke gate integrated circuit D1, and air mass sensor 1 connects D1 by Rp, and the output terminal of D1 inserts central processing unit 3, and the other end of Rp is connected with hummer 5 with alarm lamp after connecting R1.

As shown in Figure 2, described central processing unit 3 is by Sheffer stroke gate integrated circuit D2, D3, D4, resistance R 2, R3, R4, capacitor C, triode V, diode VD and relay K are formed, the end of D2 connects the D1 of wave filter 2, output terminal is connected with alarm lamp VL by R4, D3, D4, R3, the C mutual group becomes audio frequency oscillator, BL is connected with hummer, the base stage of triode V is connected between D2 and the D3 by R2, collector connects diode VD and relay K respectively, grounded emitter, the other end of diode VD and relay K is connected D4, and is connected with hummer 5 with alarm lamp.
