In recent weeks we did a lot tests to our tinyBrd. This was due to new Nettigo tinyBrd Core (integration with Arduino IDE). With v1.1b release we have lowered current consumption even more.
Now, in sleep mode tinyBrd with NRF24L01+ and DS18B20 takes only 4-5 µA (vs 9-10 µA on previous software). During sending data it takes 15 mA (vs 18 mA before).
Our test case is sending data (temperature) read from DS18B20 to RPi every 30 seconds and tinyBrd is powered by singe coin battery (CR2032). How does it work?
