Guyzz i'm building a tempsensor for a "Mini Oven" SMD soldering.
I am going to use the below "kit" & sensor.
PT1000 measureboard (German , but schematic is "universal)
Comps pg3 , Schematic pg6
PT-1000 Sensor (400 C)
I have Zero experience in RTD's , have only played with NTC's or DS1820's.
And was wondering if one of the more experienced with PT100/1000 would have a look at the schematic to see if the circuit is OK (Sometimes Pollin designers make some bad shortcuts).
As it's for the reflow curves i guess "ultra precision isn't needed" , but i'l like to know what i can expect.
I'll use an AVR , but do i need one with differential if i use the "Kit" , if not i have some M328's else M32
I have some (alot of) MCP1541 SOT-23
MCP1541 is a low power, high precision voltage reference. It provides a precise output voltage of 4.096V
Would they be of any significant use on the aref pin ?
Any hints would be appreciated , and also ... was there something about cold junction ? or ???
