Features: MAX31865, an easy-to-use thermistor to digital output converter optimized for use with platinum resistance temperature detectors (RTD). RTD sensitivity of external resistance setting, high-precision Δ- ΣADC converts the ratio of RTD resistance to reference resistance into digital output. The MAX31865 input has over-voltage protections up to ±45V, providing configurable RTD and cable open circuit and short circuit conditions detection. The MAX31865 can meet almost all your RTD requires, and can even compensates for 3-wire or 4-wire RTD for better accuracy. Connect to any microcontroller via SPI and read the resistance ratio from the internal ADC. Could be used with any microcontroller, 3.3V regulator and level shifting, could be used with any 2, 3 or 4 wire PT100 RTD. Specifications: Material: ABS+Printed Circuit Board Module Board: Approx. 3.5x3.5cm/1.38x1.38inch Supplementary Parameters: PT100-PT1000 Package Includes: 1x MAX31865 Platinum Resistance Temperature Detector Module Kit note: Please allow 0-1cm error due to manual measurement, make sure you do not mind before you order. Please allow slight chromatic aberration due to different display resolutions.
