Test purposes
Remove backside center ventilation holes, pls help to conduct climatic chamber test of the temperature/ humidity accuracy response time when with/without these ventilation holes.
Test conditions
- Sensors (battery charged full) are paired the iCreatec gateway and apps.
- Place sensors inside chamber, 2pcs existing + 2pcs without backside ventilation holes, stick on vertical wood stand (simulate user case like wall mount)
- Set climatic chamber to temp 0C, 50%RH.
- Once chamber reached the 0C, 50%RH, record sensors’ temperature & humidity every minutes (using icreatec apps).
- Record data for 30min. recording the change rate about T/H climatic sensitivity .
- REPEAT above, but setting climatic chamber “25C, 70%RH”, “45C, 90%RH”.
tips: Add “50C, 90%RH”
Test setting
1 Zigbee +T/H sample -> gateway --> Wlan
2 used a moble phone + icreatec apps
Test recoding:
1 The sample of A439-1 is out of line
remark: No power - Battery supplier engineers say that when the battery runs out of power, it will quickly sink to about 2.75v, and then, when the protection function moves, Pack will cut off the output.The Cell will go back above 3V.
2 Verify that different locations affect test data
Remark ：sample error precision is about 1 ’C
3 The gateway and apps is temporary using iCreatec platform. They modify onhand source just for our PS testing. May be it is bug
Test results
With our three sample (without Temperature-9139-1) test cases set up, we can now look at some different types of test results.
1 Rate of temperature change ---> ok
2 Power analysis --> 240mA / 8H
