HydroSense: Sonde

The Sonde utilizes off the shelf sensors, a simple enclosure, and a custom circuit board to dramatically reduce costs. The Sonde is very much a test bed for novel low cost sensing technologies and can be supplemented with third party SDI-12 sensors for field tested readings.  The Sonde enclosure is also a study in novel low cost technologies at only $120.  The Sonde enclosure is designed to be able to be fabricated by any university machine shop with the provided drawings.  Features include:

• Integrated Arduino Leonardo
• SDI-12 Interface for power and data
• Sensing probes and circuity:
  • PH Sensorex General Purpose Electrode (0-14pH)
  • ORP Sensorex Laboratory Electrode (+/- 2000mV)
  • DO Sensorex DO1200 Probe (0-20mg/L)
  • Conductivity Sensorex CS150 Probe (0 – 2000uS)
  • Temperature Atlas Sci. ENV-TMP (-20 – 133°C)
  • Pressure Atlas Sci. Ixian Probe (0 – 100PSI)\
  • Ports for 1 Atlas Scientific EZO Sensors
