It features automatic compensation for wire resistance, supports multiple wiring configurations (2, 3, or 4-wire), and interfaces seamlessly with microcontrollers via SPI. Designed for professional-grade accuracy and stability, it includes a 0.1% tolerance reference resistor and is 5V compliant with onboard voltage regulation and level shifting. ## Description For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 1000 ohms at 0°C, thus the name PT1000. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT1000's have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability. However, to get that precision and accuracy out of your PT1000 RTD you must use an amplifier that is designed to read the low resistance. Better yet, have an amplifier that can automatically adjust and compensate for the resistance of the connecting wires. If you're looking for a great RTD sensor, today is your lucky day because we have a lovely Adafruit RTD Sensor Amplifier with the MAX31865 breakout for use with any 2, 3 or 4 wire PT1000 RTD!If you have a PT100 RTD , please visit this page to purchase a version of this board with the reference resistor for 100-ohm RTD. DsWe've carried various MAXIM thermocouple amplifiers and they're great - but thermocouples don't have the best accuracy or precision, for when the readings must be as good as can be. The MAX31865 handles all of your RTD needs, and can even compensate 3 or 4 wire RTDs for better accuracy. Connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC. We put a 4300Ohm 0.1% resistor as a reference resistor on the breakout. We have some example code that will calculate the temperature based on the resistance for you. We even made the breakout 5V compliant, with a 3.3V regulator and level shifting, so you can use it with any Arduino or microcontroller.E ## Features - In this resistance sensor, the resistor is actually a small strip of Platinum with a resistance of 1000 ohms at 0°C, - to get that precision and accuracy out of your PT1000 RTD you must use an amplifier that is designed to read the low resistance. ## Product Details - **Item dimensions L x W x H:** 3.74 x 2.56 x 0.2 inches - **Voltage:** 5 Volts - **Manufacturer:** ADAFRUIT - **Maximum Supply Voltage:** 5 Volts - **Minimum Supply Voltage:** 2.7 Volts ## Images ![Adafruit PT1000 RTD Temperature Sensor Amplifier - MAX31865 - Image 1](https://m.media-amazon.com/images/I/71f1no7WEKL.jpg) ![Adafruit PT1000 RTD Temperature Sensor Amplifier - MAX31865 - Image 2](https://m.media-amazon.com/images/I/61rFQA8m2KL.jpg) ![Adafruit PT1000 RTD Temperature Sensor Amplifier - MAX31865 - Image 3](https://m.media-amazon.com/images/I/61AwdlV8n9L.jpg) ![Adafruit PT1000 RTD Temperature Sensor Amplifier - MAX31865 - Image 4](https://m.media-amazon.com/images/I/71HE9NC8UKL.jpg) ![Adafruit PT1000 RTD Temperature Sensor Amplifier - MAX31865 - Image 5](https://m.media-amazon.com/images/I/71CpxDsmnJL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/381826343-adafruit-pt1000-rtd-temperature-sensor-amplifier-max31865](https://www.desertcart.co.uk/products/381826343-adafruit-pt1000-rtd-temperature-sensor-amplifier-max31865) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
