Parts
I could've chosen some better components if I would had more time. But being worried that they do not arrive usually in time I ordered earlier. This is how I ended with a unidirectional communication instead of a bidirectional one "user<->object". Anyway I am pleased with that the RF worked from the first flip of the switch. Also the pressure sensor is a delight to use, just supply the power and read the voltage signal. You have to be careful though to subtract the offset, usually around 0.2V (mine had exactly 0.2). It is worth the money to have conditioned and ready to use signal out of an electronic component.
