The NTC 10K Thermistor Temperature Sensor is a compact temperature-sensing component used to read temperature changes in irrigation controllers, grow rooms, greenhouses, water tanks, and DIY electronics projects. As an NTC (Negative Temperature Coefficient) thermistor, its resistance drops as temperature rises, giving you a reliable signal to track. It suits home gardeners building smart setups, hydroponics enthusiasts, and hobbyists working with microcontrollers and automation boards.
Key features
- NTC 10K thermistor for responsive temperature sensing.
- Negative temperature coefficient: resistance changes smoothly with heat.
- Small, lightweight form that fits tight enclosures and probes.
- Commonly compatible with Arduino, ESP boards, and irrigation controllers.
Typical uses
- Monitoring soil, air, or water temperature in irrigation and hydroponics systems.
- Climate sensing inside greenhouses and grow rooms.
- Temperature feedback for thermostats and automation projects.
- DIY electronics, learning kits, and prototyping.
How to choose / tips
- Confirm your controller or board expects a 10K NTC input.
- Keep the sensor close to the spot you want to measure for accurate readings.
- Protect the leads from moisture when used near water or soil.
