Description of the drawings
Fig. 1 is the circuit diagram that this utility model gas leak monitors audible-visual annunciator.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further.
As shown in figure 1, the circuit of gas leak of the present utility model monitoring audible-visual annunciator using gas sensor QM,
Building, the minus earth of 6V set of cells GB connects after positive pole concatenation switch SW for 555 integrated circuits, Y976 integrated alarm circuits
The measurement pole A of gas sensor QM, one end of resistance R1 and R2,8 feet of 555 integrated circuits, the other end air-sensitive of resistance R1 are passed
One end of another terminating resistor R3 of the heated filament pin f1 of sensor QM, resistance R2 and 7 feet of 555 integrated circuits；Gas sensor
The measurement pole B of QM connects one end of adjustable resistance RP, 4 feet of regulation 555 integrated circuits of termination of adjustable resistance RP, gas sensor
The other end ground connection of the heated filament pin f2 and adjustable resistance RP of QM；One end of another termination capacitor C1 of resistance R3 and 555 integrated
