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, ...
