How to Control a Relay Using NTC Thermistor & LM393 Comparator in Proteus

This video demonstrates a temperature-controlled relay system using an NTC thermistor and LM393 comparator in Proteus Software. The circuit automatically turns on/off a relay based on temperature thresholds, ideal for applications like cooling systems or overheating protection. Key Features: NTC Thermistor: Detects temperature changes and adjusts resistance accordingly. LM393 Comparator: Compares sensed temperature to a setpoint (adjustable via RV1). Transistor Switching (2N2222): Drives the relay coil. Protection Diode (1N4007): Prevents voltage spikes from the relay. LED Indicator: Shows active status. How It Works: Temperature Sensing: NTC thermistor resistance decreases with rising temperature. Voltage Comparison: LM393 compares the thermistor voltage to the reference set by RV1. If temperature exceeds the threshold, the comparator output goes HIGH. Relay Activation: HIGH signal turns on Q1 → Relay RL1 activates → Fan or load turns on. ⚠️ Safety Note: Always use heat sinks on high-power components. 🔔 Subscribe for more tutorials, and hit the bell for updates!
