Sensebender Micro

Yes, you can use it without using the temp/hum sensor....

I just assumed, that as you wouldn't make use of it, you would like to have it removed from the board as well..

[petoulachi]

Well I do, but I think that using a Arduino Pro 3.3V will be less effecient, but maybe I'm wrong ?

I'm currently using temp/hum/motion sensors with Arduino Pro 5V, but they are not battery powered. Now I need to make very small sensor with battery, and I thought that maybe this sensebender board is my solution ?

[Anticimex]

@petoulachi to make the pro mini as efficient as the SenseBender, you need to cut some traces on the board. There are forum topics for battery optimizing a pro mini. The SenseBender has these optimizations built in.

[petoulachi]

That's why I think i'm going to go with this senseboard.
But I want to be sure that some connectors (D3 ?) support interrupts ? The goal is to have the sensor always in sleep mode, and wake up on interrupts only.

@petoulachi D3 can be used for interrupt, just tested it and it works.

I vote for one cheap Sensebender version without the temp/hum sensor on it. It will be the perfect door/window sensor.

@nikos1671

It has been up before, but back then it was decided that we don't save that much (2-3 $ or something like that). It might also be lower production quantities, which also keeps the price up..

@tbowmo just curious do you guys know how many of these you've sold?
I've bought about 15+ :)

[hek]

@mvader
Then you've bought almost 2% of them :)

We're deeply grateful for yours and others support of the MySensors project.

[petoulachi]

Ordered 6 board too ! I'm glad to support MySensors project !

I've got 3 coming, can't wait to figure out what I'm going to use them for :)

I'm deploying mine all over the house.
in my attics, garage, shed. bedrooms. etc
I've attached motion and lux sensors to several of them already.
I tested / proof of concept adding IR transmitters. but these will likely need to be 5v nano's or something as battery power probably won't work with the IR and staying away waiting for messages from the controller.

Got 3 up just using the built in temp/humidity, making sure all looks ok. Will slowly add motion.

Any suggested motion sensor for these guys?

I'm using that HC501 PIR
you can connect to the side pin and use 3v instead of the 5v

[GertSanders]

@mvader Can you elaborate how you use 3V on the HC501 ? Which side pin ? Can you post an image ?

[mvader]

@GertSanders
if you look at this image
on the left side where it says "H" by the 3 pins with the jumper.
i take off the jumper and connect 3v to the H pin
works great.

@mvader Thanks !

My Sensebender node started June 10 is still going strong.

[Anticimex]

@hek nice, what tool do you use for logging/graphing? Or is it exported and post-processed?

[hek]

@Anticimex

Datamine for Vera. The actual data is stored to my NAS (mounted from vera).
