Sensors

  • Determine required sensitivity and periodicity for each sensor.

Water Temperature

  • Colin

RTP - Ruggedized Wide Range Temperature Probe

  • 9 or 12 bit resolution
  • 12 foot CAT 5 cable
  • Dallas Semiconductor DS18S20 or DS18B20 sensors
  • uses 1-Wire communication protocol

The RTP temperature probe is designed for wide temperature range applications requiring excellent chemical resistant properties and sensor submersion.

pH

Redox Potential

  • Mikio

Conductivity

  • Maduna

Pressure

What kind of pressure? Ask Mike.

  • Maduna

Talked to mike. He says he doesn't know what pressure was doing on the list. -Jeff

Nitrate Levels (NO3?)

  • Bryan

Dissolved Oxygen

  • Jeff

Sulfide Concentrations

  • Colin

Turbidity

  • Jeff

Mike says that we could build a turbidity sensor using LEDs and fiber-optic cables without too much difficulty. He is willing to help with construction if necessary.

Batteries

  • Heating and cooling.

Enclosures

Solar Panels

SBCs

  • Power over ethernet? not supported by TS or Gumstix.
  • Heating and cooling.
