Datalogging and sensors:
- Carbon dioxide and oxygen sensors
Carbon dioxide and oxygen sensors
Detecting carbon dioxide 01:
Detecting carbon dioxide with a sensor. Why not use your carbon dioxide sensor to monitor your working environment?
Dissolved oxygen sensors practical idea 01:
Using two different dissolved oxygen sensors for changes due to photosynthesis, respiration. Be aware of the importance of effect of temperature. Measuring the BOD, biological oxygen demand, is a potential use for the sensors.
Dissolved oxygen sensors practical idea 02:
Dissolved oxygen probes with aquatic invertebrates (Daphnia). Begin to consider the confounded variables of temperature affecting respiration rates and dissolved oxygen at the same time.
Dissolved oxygen sensors practical idea 03:
Further considerations of using sensors. Maybe investigating eutrophication and monitoring oxygen levels over time. Assess your own risk analysis.
Dissolved oxygen sensors practical idea 04:
Further daphnia and DO2. Adding water fleas to pondweed.
