    Hello,

    Can some one measure the real power consumption of the sensebender with the default sketch (humidity, temperature, battery level) running and the nrf24l01 module?

    Would like to get an idea of home many µA are used in active mode and how many µA in sleep mode the sensebender is taking.

            Jus measured power consumption:

            44.66 µA - when sleep
            between 11mA and 14mA when transmitting (every minute, default sketch)

            I was using my Fluke 287.

                My order arrived in the US midwest today (shipped from HK on June 3). I hooked one up to a CR123 to test and it worked right out of the box. I do not know much about battery operation and have a question about the battery monitoring - Do I need to alter the sketch for the CR123 vs the original 2 x AA? Or a 3V coincell?

                  Just measured mine using a uCurrent and I get the same figures with an genuine NRF24L01 and what I thought was a NRF clone...

                  45µA at sleep and about just above 10mA when transmitting.

                  Mind the mess...

                      The scope works great. But I would really need attend some sort of oscilloscope course. Soo many buttons and functions. I get lost sometimes :stuck_out_tongue_winking_eye:

                        I'm still waiting for my delivery in germany. I hope that it will arrive soon.
                        Currently I think it is stuck in customs as many others received the items already from china.

                                In Domoticz I also see sensors hemidity and sensors temperature with the type LaCrosse TX3. Does anyone know what they are?

                                  I think that occasionally, domoticz only get the temperature, or the humidity in a single transmission, and then decides that it's another sensor type and therefore create a new instance for it.

                                  Sensebender always sends both temperature and humidity readings together (in two different messages, as it's two different sensor child ids that is used).

                                    How many would be interested in a Sensebender Micro LE (light edition), and how many units would you buy?

                                    The Light edition would be without Si7021, and external flash.

                                    I do not have any prices yet, as we need to have some expected sales figures to give to our partner. We need batch sizes of at least 100 units (preferably larger like 200) otherwise setup fees, etc. would eat away on the savings from removing the components.

                                      I would take 3-5 depending on the prize.

                                        @tbowmo It's really going to depend on the price. It would have to be a significant savings to drop the Si7021 and Flash for me.

                                          I haven't got any numbers from itead, but from the prices that I get from mouser, we could probably save around 4$ if we skip Si7021 and external flash.

                                          This is still more than the cheap mini clones etc. but the problem here, is that we are running in low volume batches. The setup fees for each batch is rather high, and this has to be divided out on each board in the batch.
