Hey hello Chinmay...i m doing good and hope ur good too :-) nice to see u after many days...
yes ur right its currently our month of ramadan and i m fasting entire day ....and i dont think u need to be taught few urdu words because u spelled them right moreover theres not much difference between urdu and hindi :-) anywayz thanx for wishing the month of ramadan :-)

hi m. mohsin

best wishes to u for the month of ramadan

one thing i want to ask u from where do i get this Humidity sensor HIH-4000-0001 in delhi or NCR

because i am nt getting it from nywhere

please provide me full address from where i can get this sensor in delhi

hello ankit.......

i think u hv nt read the black book deeply...
see chapter 4 whr ckts r described...
if u hv chk the datasheet of HIH-4000...u must hv notice dat der is 4 sensors in this series.... i advice u to go 4 HIH-4000-0004. coz it will cost u less den other 1. i bought it 4m a internatinal distributer by shiping n it cost me 2100 bucks... if u wish i can resell the sensor to u wid 50% discount as itz no need to me now. n the sensor is working perfectl..

well ankitgupta u must contact chinmay for humidity sensor...i cant help u much about ur local market in india because i m from Lahore,Pakistan. :-) ...and also in my local market it was available from only one shop...
Chinmay is right...i used HIH-4000-0003....it cost me round about 1500 PK Rs ....and it was giving perfect humidity value...

the only thing u can do is to go for online shipment as i suggested u earlier....www.digikey.com.....u can chk this site

ok mr. chinmay das

but how can i contact u where do u live ??????

one more thing i read ur black book in the snapshot u have described the switch board in which there are 4 switches 2 are mode selection and 2 are toggle switches

but as i know only one mode selection switch is used which is connected to pin 3.2 of uc

so what is the use of 2nd one

and also where the two toggle switches are connected because it is nt described in the ckt diagram

please provide me ur address also so that i can contat u for the humidity sensor

ankitgupta ur r really confusing up urself with this project....plz do read the tips on main page those will help u :-) dont worry about the switches ... i already told u that the ckt diagram is not 100% ... u will have to sort out some problems urself...like u i was also initially confusing my self with all these switches...but as i got deeper into the project everything became relatively easy to be sorted out...so plz start ur project without disturbing urself in the start with such things...u will get to know automatically at the end :-)

thanks MM
