Precise wattmeter with Arduino Nano

Precise wattmeter with Arduino Nano.
Finished the prototype.
It can measure from - 70 dbm to + 10 dbm up to 500 Mhz. 
Can be used with ham radio, too. 
For example:
radio of 100 Watt = 50 dbm 
- max input 10 dmb = 40 db attenuator (MINIMUM).
If you like, contact me.
