help plz very very urgent

hi all
i am a new member and plz plz i need help n my project which is about ph sensor
all i need is a simole design for a conditional circuit that is used to measure the value from the ph sensor
plz all help me soon

 

Can you give us a link to your pH sensor. What is your project about besides implementing a pH sensor?

 

If it's a calomel electrode, the output is 59.2 mv/pH unit. You just need a high impedance amplifier to buffer the electrode output.

 

i will send u the name of the ph sensor i need to use when i buy it and thnx all

 

I for one am extremely impressed with the "very very urgent" nature of your original request.

 

IP suggests they are located in Palestine, possibly Essen. Perhaps "urgent" is a translation error of some kind. Did they really mean عاجل

 

Can I draw the OPs attention to this. Without any proper input this topic is going nowhere.

Dave

 

Sorry to drift off topic but what does the abbreviation 'OP' stand for, original poster? I've seen it here a few times but never could find the meaning. Thanks

 

Either "opening post(er)" or "original post(er)" dependant on context.
