About this item

The 7Semi PT100 RTD 3-Wire Temperature Sensor Amplifier Breakout Board utilizes the MAX31865 RTD-to-digital converter to provide precise temperature measurements from PT100 RTD sensors. Supporting 2-, 3-, and 4-wire configurations, it compensates for lead resistance to enhance accuracy. The board interfaces with microcontrollers via SPI and operates at 3.3V or 5V, making it suitable for industrial and laboratory applications. With built-in calibration features and fault detection, it ensures consistent, reliable readings. Ideal for thermal cycling experiments, industrial process control, and research requiring high-precision temperature sensing.
