Status
1) earlier tests failed, no sensor signal
Potential reasons
- no power supply, - measure with multimeter
- to little power (effect) to fire up the sensor board - - don't know the power
- communication fails
On-device monitoring
- Tested the sensor with usb directly to pc and checked that there is some communication in a terminal program
- Also, open it and recheck if the sim card is correctly in the slot.
2) second test partially success, no location information, show some measured values
Potential reasons:
- static electricity
Done activities:
- Send SMS to sensor SIM card (40923931), content =<SRVADR>srv.dunavnet.eu</SRVADR>
(goal): change server address to the new one.
- Sensor discharging from static electricity.
- Sensor running without SIM card then with SIM card in order
(goal): force sensor to recheck the SIM card existence
3) third test: Temporal success with location identification and measurements :
location identification failed potential reasons:
- some wire bad connectivity.
Done activities:
- recheck wires connectivity
- static electricity discharging.
- Partial testing for different parts of the sensor.
4) fourth test: Without air sensors board the sensor send approximately half of the expected number of sending
Done activities
- Running of sensor without embedded air quality sensors board for four hours.
Result:
- sensor send 114 reading pre 4 hour where sensor settings were configured to send sense read every 1 min.
(Notes):
* The sensor needs 15 after turn it on to stabilize its sensing and to provide reliable data. * Air quality embedded sensors need to be exchanged with new one every 2 year.
caution: sensor used techs for air contents measurement based on the using of ACID (harmful chemical substance) which sometimes cause bad smell.
Needed for future testing:
- list of used commands for sensor configuration in order to simplify and accelerate testing.
- Mobile SIM card for sensors configuration.
- Sensor manual (uploaded)
Dunavnet 3 online data
