 The simplest way to measure the temperature withing the range of naturally occurring values is to use the digital sensor [[http://​www.maxim-ic.com/​datasheet/​index.mvp/​id/​2812|DS18B20]]. It can be, within a short distance, connected directly to the microprocessor,​ as shown in the following picture. The simplest way to measure the temperature withing the range of naturally occurring values is to use the digital sensor [[http://​www.maxim-ic.com/​datasheet/​index.mvp/​id/​2812|DS18B20]].

 +A verified solution consist in connecting the C3088 camera, that uses the [[http://​www.cs.cmu.edu/​~cmucam/​Downloads/​ov6620DSLF.PDF|OV6620]] single-chip.

-{{:cs:c3088.jpg| kamera C3088}}+The camera has a disadvantage in using a simple, but outdated parallel interface, that operates with 5V CMOS logicIt thus limits its connectability to modern, fast components like FPGAs or processors as presently, the 5V tolerable inputs gradually diminish among these devices. ​  
  
-Nevýhodou této kamery je, že využívá ​ jednoduchý,​ ale zastaralý paralelní interface, který pracuje s 5V CMOS logikouCož omezuje možnosti připojení k moderním rychlým součástkám,​ jako jsou hradlová pole, nebo procesory, které mají 5V tolerantní vstupy stále v menším množství.+An alternative to this camera would probably involve using some more modern camera (egone from a cell phone) with a serial interface for instance with LVDS logic.
  
-Moderní alternativou k této kameře by zřejmě mohlo být využití nějaké modernější kamery (například z mobilu), která má sériový interface třeba v LVDS logice. ​
