Hi, I'm beginner of arduino programmer. Can You explain a little this sketch? What for You use "SEND_FREQUENCY2 = SEND_FREQUENCY / 25;" ? Why You using two if statements sendTime2 and sendTime ?

Thanks
Maciej

Thanks, i will test it

Hi, great sketch! But i have a question: how to chanhe this sketch to send kwh often then once per hour? Maybe safer will be send kwh like sending wh - every minute?

Hi, where i can find light pipe lie this?

Really great job!!!

Thank You for your suggestion. I will try with Energy Monitor Shield from Seeedstudio and connect it to MySensors gateway.

Hi Everyone!

It is possible to implement energy monitor shield for Arduino to mysensors?
Maybe somebody already tried this or has some experience.
I want to add this kind of sensor (CT for 3 lines) to domoticz.
I found 2 kind of solution:

and

Please write yours comments.
Thanks

Hi,

i thougt a long time about placing such a booster on the pcb. Its quite difficult to find a good(!) booster. Lots of the cheaper booster draw a lot of current (quiescent current) - like the one behind your link. I tested only 2 until today.

This one: http://www.exp-tech.de/pololu-3-3v-step-up-spannungsregler-u1v10f3?gclid=CPmll6rH0ccCFRI6Gwod884Lxg
and this one: http://www.exp-tech.de/sparkfun-ncp1402-3-3v-step-up-breakout-prt-10967?gclid=CPCv55_H0ccCFUu6GwodKDUHwA

Current consumption differs approx 30uA between those 2 (red 70uA, green 100uA in sleepmode with sensors etc)...
Did you check current-consumption of your booster?

Actually i am changing the board size to 50mmx24mm - its a lot cheaper to order from fusionpcb (seeedstudio)...
Thats a lot.
Greetings

[▲QUICK EDIT]
Something like this? Booster soldered vertical....In this way you must select with the solder jumper how to power the board (battery direct or via booster)...

Hi ahhk,
Can You share brd files for this version? Thanks.
Maciej

Yes, great. Thanks. I'm also newbie and I don't have experience yet with booster.
The next ting is the case for this sensor, maybe with battery holder ...

Hi, it's great board, this is what i'm looking for!
The only thing is that you can add Ultra-small DC-DC 0.8-3.3V to DC 3.3V Step UP Boost not as separate module, but on the main board, for example:

What do You think?
Best regards
