How can the size of the caps affect the battery life of a sensor?
Here is the setup i have 2 sensors with dht22 attiny13 nr24l01 3aaa batteries and a XC6206P332MR 3.3v reg (3.3v to nrf).
attiny13 and dht are powered directly from battery and nrf from 3v3.
On one i have 0.1uf ceramic cap and 220Uf electrolyte on battery side and on 3v3 side from regulator. On the other i have 0.1uf ceramic cap and 10uf ceramic cap on battery side and on 3v3 side from regulator.
The reason for using 3aaa is that the dht22 need 3v+ for the humidity readings to be accurate.
The one with 220uf electrolyte have lasted well over a year so far. but the 10uf one only lasted half a year, all other components are identical as far as i can tell. Any ideas why the diff are so big?
