Potentiometer RP is used to set monitoring voltage parameters. When the parameter is within the set temperature range of the potentiometer RP, the potential of the second pin of the detection chip IC is between high level and low level, the twelfth pin outputs a low level, the tenth pin and The eleventh pin outputs a high level, the second LED V2 lights up, the first LED V1 and the third LED V3 do not emit light, and the alarm B does not sound. When the voltage is low, the resistance of the detection terminal AB increases, which increases the voltage of the second pin of the detection chip IC. When the second pin and the fifth pin of the detection chip IC become high level, the tenth The first pin and the twelfth pin will output a low level, so that the first light-emitting diode V1 and the second light-emitting diode V2 are lit, the second diode D2 and the transistor VT are turned on, and the alarm device B emits an alarm sound. When the voltage increases, the resistance value of the detection terminal AB decreases accordingly, so that the voltage of the second pin of the detection chip IC decreases. When the voltage is high so that the second pin and the fourth pin of the detection chip IC become low level, the tenth pin and the twelfth pin output low level, so that the first light-emitting diode V2 and the third light-emitting diode V2 V3 lights up, the third diode D3 and the triode VT are turned on, and the alarm B sends out an alarm sound.
