The alarming circuit is composed of comparator A4 and buzz circuit. When the temperature is more than 29 ℃, the A4 inverse end set potential compare with the A2 output. A4 outputs high level. The BG2 is conducted. It sounds bees alarm and at the same time the LED3 bright alarm lights (orange light) to remind the officer on duty to note out fault. It makes temperature control in the most suitable range. This circuit can make the temperature in 28 + 1 ℃, when the temperature is more than 29 ℃, the circuit will sound and light alarm signal to remind people.
