Platinum RTD Sensor - PT1000 - 3 Wire 1 meter long

OverviewPinoutWiringRelated groups
Platinum RTD Sensor - PT1000 - 3 Wire 1 meter long — Adafruit — 3984

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.

Pinout

  • RTD lead A

    One side of the PT1000 platinum resistor. Adafruit states two wires connect to either side of the platinum resistor.

    Type · passive
  • RTD lead B

    Other side of the PT1000 platinum resistor. Adafruit states two wires connect to either side of the platinum resistor.

    Type · passive
  • 3-wire compensation lead

    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.

Air quality

Choose between MQ gas sensors, VOC/eCO2 indoor-air sensors, true CO2 modules and particulate sensors without treating every air-quality breakout as the same detector.

Light and colour

Photoresistors and color sensors both respond to light, but they expose very different signals and are not sensible drop-in substitutes.
