FIRE DETECTION & ALARM DIY PROJECT ASSEMBLED KIT

Brief 
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 Alarm via relay. The Alarm stops once the thermistor cools down. 

Project Features
Fully Assembled project kit
Slide switch on/off control on board
Transistor based circuit
Fire Sensor (Thermistor)
DC Buzzer interface
9V Battery Included 
Includes Storage Box & Project Document
PCB DOES NOT CONTAIN ANY LOGO OR TRADEMARK, Hence can easily be used for school/college project purposes
