Northern Widget sensors
Walrus
Measure water levels (or atmospheric pressure) and temperature with this encapsulated sensor.
Haar
Waterproof atmospheric temperature, pressure, and relative humidity sensor.
LiDAR Lite Symbiont
Turn a raw Garmin LiDAR Lite sensor into an integrated tool to measure range and orientation.
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
Dyson
Long-wave and spectrally resolved short-wave radiation.
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.
