| Support | Email & WhatsApp 24/7 |
Key Features
- 100K Ohm at 25 degreesC: Standard resistance value widely supported by 3D printer firmware (Marlin, Klipper, RepRap) and microcontroller libraries.
- 3950 Beta Coefficient: Provides accurate temperature-to-resistance mapping for precise thermal readings across the full operating range.
- Wide Temperature Range: Measures from -40 degreesC to +260 degreesC, suitable for heated beds, hot ends, environmental monitoring, and industrial sensing.
- Fast Thermal Response: Small glass bead construction enables quick response to temperature changes for real-time monitoring.
- Easy Integration: Two-wire connection works directly with Arduino, ESP32, Raspberry Pi, and most microcontroller ADC inputs using a simple voltage divider circuit.
- Compact & Durable: Glass-encapsulated bead resists moisture and provides long-term stability in demanding environments.
Why Choose This?
- 100% authentic from trusted component suppliers
- 1-5 day shipping, 7-8 day delivery from Bengaluru warehouse across India
- Expert technical support for circuit design and integration
- Consistent and calibrated readings out of the box
- Compatible with the most popular 3D printer and microcontroller platforms
Project Ideas
- 3D Printer Upgrades: Replace or upgrade the thermistor on your hot end or heated bed for more accurate temperature control and better print quality.
- Arduino/ESP32 Weather Station: Build a digital thermometer or weather monitoring system using a voltage divider circuit and the Steinhart-Hart equation for precise readings.
- Smart Home Temperature Monitor: Pair with an ESP8266/ESP32 and MQTT to create a wireless temperature sensor node for home automation platforms like Home Assistant.
- Incubator or Fermentation Controller: Monitor and regulate temperature in DIY egg incubators, sourdough proofing boxes, or homebrew fermentation setups.
- Industrial Thermal Protection: Integrate into motor winding temperature monitoring or power supply thermal shutdown circuits for equipment safety.
- Learning & Education: Ideal for students learning about resistance-temperature relationships, ADC conversion, and sensor interfacing with microcontrollers.
How to Connect
- Basic Voltage Divider: Connect one lead to VCC (3.3V or 5V), the other lead to an ADC pin and a fixed 100K resistor to GND. Read the analog value and convert using the Steinhart-Hart equation or a lookup table.
- 3D Printer: Connect directly to the thermistor input on your RAMPS, SKR, or other 3D printer control board. Select thermistor type "1" (100K with 3950 beta) in your firmware configuration.
- Pull-up Resistor Value: Use a 100K Ohm fixed resistor for best accuracy around room temperature. Use 4.7K for better resolution at higher temperatures (200 degreesC+).
What's in the Box
- 1x 100K Ohm NTC 3950 Thermistor (glass bead, insulated leads)
- Documentation and technical support access
