Temperature Sensor Whisker

AST1021

Whisker Kickstarter Item


Note: This item is currently only available on Kickstarter, it will be for sale on our site after the Kickstarter is complete and rewards have been fullfilled



DESCRIPTION

This Whisker features the PCT2075 Temperature Sensor. This sensor has a range of -55°C up to 125°C and communicates over the I²C bus.

The Whisker Adapter TinyShield (ASD2022) incorporates level shifting and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.

    TECH SPECS

    PCT2075 Temperature Sensor Specs

    • Temperature range from -55°C up to +125°C
    • 11 bit ADC that offers a temperature resolution of 0.125°C
    • Temperature accuracy of:
      • ±1 °C (max.) from -25 °C to + 100 °C
      • ±2 °C (max.) from -55 °C to + 125 °C
    • Programmable temperature threshold and hysteresis set points during operation
    • Supply current of <1.0 µA in shut-down mode for power conservation
    • Stand-alone operation as thermostat at power-up

      TinyDuino Power Requirements

      • Voltage: 3.0V - 5.5V 
      • Current: 70.0 µA (Normal Mode).  Due to the low current, this board can be run using the TinyDuino coin cell option
      • Current: <1.0 µA (Shut-Down Mode)

      Pins Used

      • A5/SCL - I²C Serial Clock line
      • A4/SDA - I²C Serial Data line

      Dimensions

      • 10mm x 10mm (.393 inches x .393 inches)
      • Max Height (from the lower bottom of Whisker to upper top Whisker Connector): 3.70mm (0.15 inches)
      • Weight: 1 gram (.04 ounces)

      NOTES

      • You can also use this shield without the TinyDuino – modifying the connecting cable by removing the opposite connector and stripping/tinning the wires, you can solder the connector cable to any other microcontroller board of your choice!
