Current goals (RaspberryPi-Arduino relationship, Website, Database discussed) next steps determined.
Reports:
Ben Van de Brooke:
Thomas and I met today to work with the new Arduino and sensors. It was a very productive meeting!

RE: Vernier Sensors Feb 2, 2017
- ISE Electrodes are not designed for 24/7 operation, they should not be used in a setting for continuous monitoring.
- Flow and Temp should be fine for continuous monitoring.
- Conductivity should work for an extended period of time, but you will need to check and / or calibrate the device.
- Please note that pH and conductivity can interfere with each other as the conductivity probes pushes a current through the water, so sensors that are placed in-situ close to each other can cause problems.
- O2 and Humidity - are sensors that measure air - not liquids. The O2 sensor should be fine for a period of 4-5 years, although once again it will require periodic calibration. The humidity sensor should last for an extended period.
- Dissolved O2 : ODO-BTA - optical DO can be left in water for an extended period - but only the shaft for about an inch - the entire thing can be immersed up to the sensor housing - but not indefinitely. Just the tip is fine. The device is solid state and will last for years. The tip will need to be replaced every few years.
