Northern Widget sensors

Walrus

Measure water levels (or atmospheric pressure) and temperature with this encapsulated sensor.

Walrus

Haar

Waterproof atmospheric temperature, pressure, and relative humidity sensor.

Haar

LiDAR Lite Symbiont

Turn a raw Garmin LiDAR Lite sensor into an integrated tool to measure range and orientation.

LiDAR Lite Symbiont

Includes:

  • 3-axis MEMS accelerometer to measure laser orientation
    • No need to position the sensor looking straight down to measure level: can trigonometrically coorect
    • Will record whether the sensor has been disturbed
  • Power management and filtering for high current during laser shots
  • Failsafes to reset the LiDAR Lite when its firmware locks, thus isolating the rest of your system from a potential failure mode.
  • Full instructions for enclosure and mounting

Support for off-the-shelf sensors

  • Tipping-bucket rain gauges
    • Reed switch or Hall-effect sensor
    • Project Tally (optional)
  • T9602 temperature and relative humidity sensor (add library link)
  • Decagon / METER soil moisture probes (do we even have a library, or just AnalogRead()?)
  • Maxbotix ultrasonic rangefinders (library link)
  • Thermistors (obviously – mention on-board Vdiv)
  • Kipp & Zonen solar-radiation sensors (mention instrumentation amp)


Northern Widget prototypes

The following sensors are still in earlier stages of development.

Calypso

Dual-mode turbidity sensor: measures both transmission and scattering.

ThermalStake

Rugged subsurface temperature profiler: thermal conduction and fluid flow.
