ü Images of development / construction of the Project
1 .- We did the necessary evidence to breadboard the circuit afterstarting work for the tablet phenolic
2.-We did the circuit PCB WIZARD
3 .- Iron the plate and the next step was to put it into ferric chloride.
4 .- We take the ferric chloride plate and proceeded to clean and sanded
5 .- We drilled the tablet.
6 .- We soldered the components to the board
7 .- Place the sensor in a chassis

| Date | Activity |
| 01/11/11 | It talks about the initial conditions of the project. |
| 05/11/11 | They start looking for projects for implementation .. |
| 06/11/11 – 14/11/11 | There are several projects, but none for its realization convinces |
| 15/11/11 | It sends the justification and the diagram of the project to be accepted |
| 16/11/11 - 27/11/11 | They begin to test the project on the breadboard to test it. It begins with the report and were screened for the website. |
| 28/11/11 – 01/12/11 | It begins to make the plate, with all their procedure in order to be delivered on the days indicated. |
| 02/12/11 | Delivered the project and the website duly completed and in operation. |

ü Chemical Waste Treatment (related to the circuit board)
To make the printed circuit board used a copper that was sandedbefore use to remove all impurities that were contained incopper. The design of the printed circuit sheet and PNP-010 fromI iron it on the board, after this process the tablet was wetted and rubbed with your fingers to remove debris from the road and onlystay on the toner copper. Finally, ferric chloride was mixed with water in a Toper used (the first liquid in larger quantities) wherethe tablet was dipped to remove all unnecessary copper and obtain the desired circuit, the plate was cleaned with water afterthis process and the excess of ferric chloride was dropped into the drain but not before being well diluted in water as indicated by the standards of waste disposal.
ü Conclusion
Operational amplifiers and more specifically, the analog to digital converter are quite useful to measure, observe, analyze physicalvariables to be obtained by a circuit delivering sinusoidal signals or analog signals in general, is what was observed in this project to make a gauge of the physical variable: temperature. The implementation of this circuit was also useful for mixing and understand other circuits such as the PLD's though made as a simple function to decode the digital signal provided by the ADC.It is interesting to note that at this point was reached starting from an n-type material other p, ie, a diode, then evolving into atransistor and hence forming the operational amplifiers that finallythey could find one of the most important the ADC. Overall, the project served to observe and understand the ability of the amplifier circuit of this nature
