Before doing the field test, I decided to do a basic test indoor in order to correct any hardware or software issues. In the figure below I show you the devices assembled and ready for the basic test.

In the video below I show you the test inside my house and the system worked without problems.

FIELD TEST

This is the place I chose to work.

In the image below I show you the transmitter already working.

In the image below I show you the receiver receiving the data more than 100 meters away from the transmitter.

Finally, in the video below I show you the tests carried out with this system. This design will serve as an experience to make the system with three sensors and that will be shown in the later chapters.
