Platinum RTD Sensor - PT1000 - 3 Wire 1 meter long
PT1000 platinum RTD probe on a 1 m three-wire cable, 1000 Ω at 0°C. Requires a dedicated amplifier (e.g. MAX31865) to convert resistance to temperature; not directly readable by a standard ADC.

One side of the PT1000 platinum resistor. Adafruit states two wires connect to either side of the platinum resistor.
Other side of the PT1000 platinum resistor. Adafruit states two wires connect to either side of the platinum resistor.
Third RTD wire connected to one end of the PT1000 for 3-wire RTD amplifier lead-resistance compensation. Leave disconnected for 2-wire amplifiers per Adafruit.
