Hello! So I found this small transmitter board that gets activated when a magnet is removed. I do not have much knowledge in RF boards, but I was wondering if anyone could help identify the components on this board? Sadly the main IC is covered. Any input would be greatly appreciated!

the glass tube at the bottom of the picture is a reed switch. to make this a relay, it would also need to have a solenoid.
little black rectangles with 3 digits are resistors. their value is shown in Ohms and last digit is number of zeroes. ("104"=100000 = 100k, "473"= 47000 = 47k)
the similar looking white/gray/beige parts are capacitors. they do not have value marked.
blue thing on the right is likely some sort of trimmer... not sure what type (capacitor /potentiometer).
