The Daily Diary

Since its initial development for use on birds, its lightweight design and size has enabled the Daily Diary to become an essential tool for monitoring behaviour and motion for both people and animals. Our devices have so far been deployed on a wide range of subjects including people for health and psychology studies, condors in the Andes, albatross in the South Indian Ocean, roe dear in the Alps, camels in India and polar bears in Alaska.

The Daily Diary can monitor motion, direction, speed, and external conditions affecting the subject, and can log this information at extremely short intervals (to a maximum of 60Hz) providing an extremely detailed dataset. 

Technical specification:
  • Weight: approximately 2g (circuit not including battery/housing)
  • Accelerometer: tri-axial 13-bit resolution +/- 16g (3.9 mg/LSB)
  • Dimensions of the circuit: approximately 27 x 26 x 8 mm
  • Magnetometer: tri-axial 12-bit resolution +/- 1.3Ga
  • Temperature: range -40 - +85 C (0.1 Celcius steps)
  • Barometric Pressure: range 300 - 1100 hPa (0.01 hPa steps) although the barometric pressure sensor will not function when in a sealed unit
  • Depth sensor: range down to 200m (resolution estimated to be about 1m)
  • Simple LDR (light dependent resistor) to log dark to daylight transition (12 bit)
