Description
The project is a FULLY ASSEMBLED KIT. This project includes a thermistor which is connected to BC547. Thermistor acts like a variable resistance based on the heat it is exposed to. Under heat conditions, the thermistor lowers its resistance, increasing the current across the first transistor which will turn on the Buzzer via relay. The Buzzer will be on till the Thermistor gets cooled.
