I want to use LoRa RA-02 module with 433MHz. Using LoRa class A (most of the time the controller will sleep and wakeup each 1 minute to send abd receive data.
I want to run in with small battery like CR2032.
How can I connect that please?Arduino is low power consumption? Can wake up each 1 minute and can connect to RA-02?
Maybe another controller?
How can I connect the controller +RA-02 to CR2032?
Great idea but not practical as you are pursuing it. See Figure 3 in this link. https://www.dmcinfo.com/Portals/0/Blog%20Files/High%20pulse%20drain%20impact%20on%20CR2032%20coin%20cell%20battery%20capacity.pdf You need to use a lot less current, the battery will not supply enough energy to start an standard Arduino. You will need a different battery and or processor.
As already mentioned, this is extremely difficult for a hobbyist to do. Arduino is not low power.
You need to choose a very low power processor and radio, and optimize all aspects of the circuit design to make a unit that will work for more than a few hours.
Can you please recommend on processor that fix for that project?
