Sensebender Micro

[hek]

Mine came in this Monday. One of them has been running since.

It is a tracked mail/package so Itead probably has the number somewhere.

@tbowmo, ah, sorry misunderstanding then. I thought it was the atsha204 that was contributing 30% of the cost, but I guess it's the Si7021, which is rather useful to have!

Yup it's the Si7021.. It's about 5$ in low quantities from Mouser (Think that itead has a better source thouǵh)

I received mine today. I would be interested in a lower cost version as well that doesn't include the temp & humidity sensor.

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.

Lucky yous, I am still waiting for delivery in Canada.
Looks as though it will be next week as Friday mail has past.

Still waiting here on the East Coast...

My two have arrived, up and running in Domoticz as WTGR800 temp + hum.

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.

and graph...

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?

@filipq

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...

I like the wallpaper.:smile: but how do you like your scope? I consider buying one myself

[hek]

@AWI

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.

[5546dug]

Got them last night in Canada.

[Porky6666]

I'm still waiting in germany, customs in this country have "Deutsche Gründlichkeit". Sticking their Nose in every bullshit ;-).
So still waiting .

Received mine yesterday.

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

[tbowmo]

@hetbeest

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).

[tbowmo]

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.
