Thank you for your reply, I am planning on using the Sparkfun SEN-0842 weather sensor. I have build a homemade reed/ magnet type anamometer and successfully ( somewhat for a homemade job) been able to verify that it does work with code using a wired connection. But implementing it to a 433/ Nrf24l01 type system for remote transmission has been unsuccessful so far any ideas/help would be appreciated. Tnx
