Sensebender Micro

[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.

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..

[mvader]

@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).

[Anticimex]

@hek cool. Can Vera do that now? Vera lite as well? Though the data miner plugin only could use USB mounts.

Na, a little hack

Hello,
I've just received my sensebender boards and start playing with it.

My first goal is to make a door sensor running on battery. I will not use the integrated temp/hum sensor for battery purpose, and use interrupt to have the sensor on sleep the majority of time.

Looking at the sketch given with temp/hum, I have one question;

on the loop function, we have

if ((measureCount == 5) && highfreq) 
  {
    clock_prescale_set(clock_div_8); // Switch to 1Mhz for the reminder of the sketch, save power.
    highfreq = false;
  } 

But I don't really understand this ; highfreq is initialized to true in the declaration, and never again. So, does this clock_prescale_set is call only once, meangin that the sensor will run at 1Mhz all the time ?
It is the 5 first mesure that are running at normal speed, and then the sensor goes into a "battery efficient" mode ?
Why waiting for 5 mesure to do so, and not doing it at startup ?

Thanks for your explanation !
