1Pc MAX31865 RTD Sensor Module Platinum Resistance Detector for PT100/PT1000
- RTD-to-Digital Temperature Converter: The MAX31865 module is designed for platinum resistance temperature detectors, converting RTD resistance into digital temperature data. It is suitable for PT100/PT1000 temperature sensing applications, industrial temperature monitoring, heating control, laboratory equipment, and embedded electronics projects.; High-Resolution 15-Bit ADC: Featuring a 15-bit ADC, the MAX31865 provides precise resistance-to-digital conversion for RTD temperature measurement. The nominal temperature resolution is 0.03125°C, allowing the module to detect small temperature changes for accurate monitoring and control.; Wide Temperature Measurement Range: This RTD interface supports temperature measurement from as low as 100°C up to +800°C, depending on the RTD sensor used. It is a practical choice for applications requiring wide-range temperature detection in industrial, scientific, and DIY control systems.; SPI Interface with Flexible RTD Wiring: The module communicates through an SPI interface and supports 2-wire, 3-wire, and 4-wire RTD sensor connections. This flexible wiring compatibility makes it easy to integrate with Arduino, STM32, Raspberry Pi, and other microcontroller platforms.; Built-In Protection and Fault Detection: The MAX31865 input includes overvoltage protection up to ±45V and supports configurable RTD fault detection, including open-circuit and short-circuit detection. With a maximum conversion time of 21 ms, it provides fast and reliable...
