Hi all,
I've been experimenting a while with an LM92 temperature sensor:
SDA & SCL with a 4k7 pull up to a PIC T_CRIT and INT connected to a 10K resistor to V+ A0 and A1 to V+ V+ = 5v
22nF over V+ and GNDI'm trying to build a reasonably accurate ambient air sensor, i've tried using an LM35 but gave this up because of the difficulty to get a good linear amplification to boost the signal to a usable level for A/D and thought a digital sensor would be the best option... Anybody got a better idea for a sensor that has got a good accuracy, not to pricy and has good availability or can fix my LM92 problem?
Thanks!
