Sensebender Micro
-
I don't know if the radio actually drives the interrupt "output" pin on it's pinheader as default, or if you have to set it up when initializing the radio (@hek might have some input on this part :))
If it drives the interrupt pin by default, then you need to either cut a trace on the sensebender, or cut / remove the pin in the pinheader on the radio module.

I think it does actually.

No, it isn't currently used by the MySensors library. It could be used to wake up the board when detecting radio transmissions...
But keeping MCU sleeping and the radio listening still uses up batteries far too quickly so I guess it's still not an option. -

Cut the radio IRQ pin and soldered a connection to D2. Tested to attach both interrupts and it works using a modified SenseBenderMicro sketch. "The Thing" will when ready be placed in my mailbox (which has mail-in and mail-out doors) and as a bonus report the outside temp, humidity and battery status. Does not solve any of this worlds biggest problems but it is fun :-)

Hello,
one simple quick question, does this board can be used to create door sensors ? I do not need the temp/hum sensors, but I'm interested with the small footprint and the battery optimized board to make smallest door sensors (and some buttons).
regards,

@tbowmo
Well can't I use this board without using the temp/hum sensor ?This board is quite small and allows to stack the radio module with minimum place. Also it works at 1Mhz, I guess it's a bit better than an Arduino Pro @ 3.3V ?
-
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 ?

@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.

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.Regards,

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

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..

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.
