Smart Temperature Sensor Circuit using LM3914 & NTC | LED Level Indicator + Fan Control#dilveersingh
In this video, we build and demonstrate a smart temperature sensing circuit using the LM3914 IC and a 10K NTC thermistor. This circuit visually displays temperature levels using a 10-LED bar graph and can also control a motor or fan automatically based on heat variation. As temperature increases, the resistance of the NTC sensor decreases ...
