      I just received two Sensebenders, but have problems getting the device to consume little power. I get totally different values as displayed above.

      With the following sketch, I get about 5,6mA in active state and 1,6mA in sleep mode with nRF24 attached. I have compared different nRF24-chips and this one consumed the least power.

      Without the nRF24, I get 4mA and 0,025mA (=25µA) during sleep mode.

      #include <LowPower.h>
      #include "RF24.h"
      
      RF24 radio(9, 10);
      
      void setup() {
      }
      
      void loop() {
          delay(8000);
          LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF);
      }
      

      As a follow-up to my previous posting, I can confirm, that using original nRF24-modules (best source seems to be https://www.itead.cc/nrf24l01-module.html), I get 0,023mA (=23µA) with nrf24 attached during sleep mode (no difference between the libraries JeeLib->Sleepy::loseSomeTime or LowPower->LowPower.powerDown).

      It is quite interesting, that so many nRF24 Modules (bought from eBay, from Amazon UK) are clones with higher power consumption. Some of them use 3mA, some have electrical short, ...
