Dear all, I'm trying to measure the batteries life time when using a TmoteSky (telosb). I would like to know whether ours results are acceptable.
I used a modification of the Oscilloscope Application from TinyOS-1.x so that we only measure Temperature, according to the following characteristics: 1) Send 1 msg every 10 reading read (~1.2 sec); 2) each msg has 10 temperature readings; 3) Sampling interval 100 ms; 4) Packet length: 33bytes; 5) No power management was implemented; 6)Using tmotesky's default transmission power (we suppose its using the Maximum); 7) Using 2 AA Alkaline batteries (Cbatt 2450 mAh). 8) As Base Station I have another TmoteSky using the TOSBase application. 9) environment's temperature was +- 25 Celsius. I am using SerialForwarder in order to count the Packets Read. According to my test I had the following results: Battery Life time: 1h 40min Receive packets: 4931 Somebody knows what are the parameters used for people who have reached measure battery lifetime around 3 and 10 days? and Somebody knows what is the maximum battery lifetime using oscope without low power management? Thank you very much, Leah
