The feature of this suite is small size, high sensitivity. It uses the sound and light to finish the alarm, and it can be used to detect the temperature. In conclusion, it has high practicability 1.Circuit introduction The circuit of this suite is very simple, it is consisted of three triodes(two S09014 and one S9015), one active buzzer, one LED and one thermistor. Adjust the potentiometer to set the temperature threshold value, use two S9014 triode to drive the buzzer, when the temperature is high than the threshold value, the LED lights and the buzzer alarms; when the temperature is lower than the threshold value, the LED does not light, the buzzer does not alarm. 2.Parameter Working voltage: DC 3~5V. PCB size: 21*30mm 3.Schematic diagram 4.Mechanical drawing 5.Components list: Package Include: 1 x DIY KIT Electronic Temperature Control Sound Light Alarm Suite DC 3V~5V.Find many great new \u0026amp; used options and get the best deals for DIY Kit Electronic Temperature Control Module Sound Light Alarm DC 3V~5V LED at the best online prices at Order2india Shopping!
