I just found a mistake in my message "Unfortunately my sensor, although it is very good for prototyping...." I don't mean the sensor modules, but the sensor board (Advanticsys EX1000). As for your question, I managed to drop the consumption about 30~40 by turning off some of the inputs with makeInput() but consumption is still high. So I thought that it could drop even further if I could turn off all the peripheral devices. I am not sure if this board is directly connected on power, in which I can't do anything. I deployed a telosb (Advanticsys CM3000) yesterday with EX1000 board and all the sensors (SHT75 and ZyTemp TN9) and transmit the voltage in every message. After almost 19 hours it is now at 2.76V (2 AA Alkaline batteries). I assume it will manage to stay alive for almost 35~40hours. Any ideas, or suggestions would be helpful. Thank you.
