Hi,
We have procured 8 THER200 and 8 VG400 sensors,

My sensor board can supply only maximum of 3.2v supply voltage , but these sensor datasheet says that it needs 3.3 to 20v DC, will these sensor will function properly at 3v ,. and these sensor needs only less than 800microA current so is there any simple way to get a voltage more than 3.3 volt for certain period(while reading the sensors )
I can provide only maxium of 3.2V as supply voltage ..

regards
chethan
 

Hi

Use a switch capacitor booster circuit (IC) see national or linear tech site for IC

All the best

Hi,
thanks for the reply .
Since already I developed the board I just want some ckt which does the above , because once in a day I need to drive the power to sensor .
