ThanX ,
I liked STH sensirion as erik suggested . Pl see in the
datasheet I have got a little confusion on page 2/9 ,it shows a graph
Fig 1 , temperature accuracy of SHT11 Transducer ,and on the left hand
side Repetablity +/- 0.1C .What I understand is if I wanna read 22.65C
then according to its accuracy graph ,I read it with an err of +/-0.6C
for SHT11 series is this *RIGHT* or I'm mistaken what is the precision
of this SHT11 transducer .I can see I get a BONUS humidity sensor with it
along with full calibration and digital interface Quite GOOD .
Can I get * HIGH accuracy and HIGH precision * with SHT series sensor .
Kai wonderfull explanation , My temp range of
interest for fine regulation is *ONLY* 20C to 35C I wanna follow a
comfort level equation for HVAC system for the Bus on wheels can I achieve an
such accuracy of 0.1C with a NTC 5K thermistor can ya please show me some
good schematic I found simple bridge on the net with no conditioning
very *RAW* and one as Bannister suggested with Opamp .
