Summary of Contents for Edu-Logger 900-230

  • Page 1 Edu-logger CO Logger Sensor Guide 900-230...
  • Page 2 CO concentration reading. Hundreds of possible experiments that can be done with the 900-230 sensor are: Monitoring of ecological systems, combustion reactions, CO consumption rates, studying photosynthesis, testing chemical solutions, hydrogen peroxide decomposition, and many more.
  • Page 3 CO2 sensor to: For On-line experiments: 900-213 USB Module. For Off-line experiments: 900-215 Battery For use with the Edu-logger Viewer: 900-272 Viewing Module and 900-215 Battery. The sensor now needs to be calibrated: Connect the CO2 sensor to the left side of a 900- 213 Module (which is connected to a computer via the USB to mini USB cable).
  • Page 4 Open the Edu-logger software. Once the CO2 sensor is detected click the “Module setup” button. Hold the probe vertically so the opening is facing the ground. Press and hold the blue “Start/Stop” button the faceplate of the sensor for 3 seconds.
  • Page 5  900-213 USB Module  A USB to mini USB cable (which comes with the 900-213) Prior to initial use the Edu-logger CO sensor needs to be offset. Please review the “Sensor calibration” section of this document on beginning on page 2 for detailed instructions.
  • Page 6 Once a CO2 sensor logo appears on the left side of the screen the probe has been automatically identified and you can begin experimentation. If the CO2 sensor is not automatically identified then click the “Search for sensors” icon to find the sensor.
  • Page 7 900-268 module. The 900-268 module will create a closed Edu-logger wifi network which will stream the Edu- logger data to a device of your choosing. Once your device is wirelessly connected to the Edu-logger network you can run experiments and collect data through a browser of your choosing.
  • Page 8 LED to the far left turns blue; this can take up to one minute. Take your tablet or smart phone, go to the WiFi settings and select the Edu-logger network which matches the 900-268 Module ID found on the back of the 900-268 device.
  • Page 9 3 times on the panel key. Repeating this operation will return the unit to WiFi mode. Operation with Edu-logger viewer Materials needed:  900-230 CO2 Sensor  900-272 Viewing Module  900-215 Battery Procedure: Follow the „Sensor Offset” guide in this document.
  • Page 10 (Off-line experiments are for when you do not have a sensor connected directly to a computer, tablet, smartphone, or Edu-logger viewer). Materials needed:  900-230 Sensor  900-215 Battery Materials needed to configure your offline experiment:  900-213 Module or 900-268 module or 900-272 Module ...
  • Page 11 Click the “Load data from sensors” button. Select which experimental data to upload. (5 experimental runs can be stored at one time on the 900-230 CO2 sensor) Restoring sensor’s factory default settings: Procedure: Connect the 900-213 to a PC, Mac, tablet, or smart device.
  • Page 12  Rugged plastic ergonomic case  Push button switch for Start/Stop experiments in off line mode  LED indicator of experiment status (blinks while collecting data)  Attached probe cased in durable plastic Note: Edu-logger products are intended for educational use.
  • Page 13 Videos, literature and other probes can be found www.edulab.com Technical background: The philosophy behind Edu-logger‟s plug and play technology is based on each sensor‟s ability to store its own data due to an internal flash memory chip and micro-controller in each plastic Edu-logger body.
  • Page 14 When the sensor is exposed to CO gas , the following electrochemical reaction occurs: Cathodic reaction + CO + 1/2O + 2e = Li Anodic reaction + 1/2O + 2e = Na Overall chemical reaction + 2Na = Na O + 2Li + CO As a result of the electrochemical reaction, electro-motive force (EMF) would be generated...
  • Page 15 Maintenance and storage:  Never submerge the Edu-logger sensor‟s plastic body in any liquid.  Do not allow liquid into the Edu-logger sensor‟s plastic body.  After using the probe wipe off all excess material, liquid or residue from the CO2 probe body.
