Control and alarm circuit diagram composed of SGZ07 sound and light alarm IC. In the figure, the circuit can work in dual-band sound, light alarm circuit by controlling the K1, K2. If the R1, R2 in the circuit are changed in the corresponding thermal resistor (measured value), it can achieve temperature control and alarm circuit.
