Hi,
I use TmoteSky sensor to get the temperature, humidity and light intensity.
I find that the reading of humidity is lower that the actual environment.
I am not sure the light reading(TSR) of light is correct or not.
I use this formula to convert the sensor data.
Humidity: -4+0.0405*So+(-2.8*10^-6)*So*So
So is raw data
Sensor reading: 52.5% (converted)
Sensor reading: about 1500 (raw data)
Actual humidity: 69%
I put the sensor in front of the LCD monitor (I have open the lamp and the LCD
monitor)
Light (TSR) : raw data/4096*1.5*10^4*0.769
(modified by 0.769*1e5*I*10000 and Vsensor=raw data/4096*1.5 and
I=Vsensor/100000 )
Sensor reading:0.281 Lx (converted)
Sensor reading:1 (raw data)
Is this the light intensity?
Can anyone help me?
