An ultra-low-power and very small arduino compatible wireless temperature sensor.

Features:

  • Very small size: same footprint as the CR2 battery holder by itself.
  • A single CR2 lithium cell provides enough power to continuously operate approx 6 to 7 years.
  • The wireless range is approx 100 meters (RFM69CW)
  • The temperature accuracy is 0.25 degree Celcius. (DS18B20 in 10bit mode)
  • Update rate of once every minute

NOTE: This design is only the sensor node. The receiver is a separate project.

The zipfile contains the gerber files and a pdf file with design remarks, full schematic, BOM, assembly diagrams, drill/pcb info and an embedded interactive 3D model view (for the interactive 3D view, use a recent acrobat reader to open the pdf file. Otherwise the last page is just empty)
