This video is about how to make a simple fire alarm circuit using Thermistor and IC LM358.
A thermistor is a variable resistor whose resistance depends upon the temperature. In this circuit I have used an NTC thermistor whose resistance is inversely proportional to temperature.
Components used :
1. Breadboard - amzn.to/3eMW9mF
2. 10k Thermistor - amzn.to/3FOPog4
3. IC LM358 - amzn.to/3zls72P
4. 10k Preset - amzn.to/3eMwSsQ
5. 10k Resistor
6. Buzzer - amzn.to/32VMZ4G
7. Jumper Wires. - amzn.to/3FKkF3P
8. 9V Battery - amzn.to/3JFmCRl
🕹My Favourite Equipment :
📷Camera - amzn.to/325QDZm
📱Tab - amzn.to/3dUZRKP
💻Laptop - amzn.to/3ywukrS
🔭Tripod - amzn.to/3saDitD
💡Lights - amzn.to/320iXwB
🎤Mic - amzn.to/3p4nneF
