Really nice, did you buy the glass plates from there ?

If not, can you please tell where you get them from ? Thank you !
@gohan said in Arduino Pro Mini Shield for RFM69(H)W:
If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it.
thank you just what i thought .
about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol
Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board.
sorry about hijack this topic, i though i was on general discussion

Perhaps I don't necessarily need to use the same pins
Both the sensors you quote are using I2C. So they both use the same 2 pins (SDA, SCL) to communicate. You can put many I2C sensors on those same pins, they each have an address to know which sensor is receiving/sending data to the master (here, your arduino).
Look for a tutorial on I2C first.
Thanks I get it now
Hi @chey, no, with the pro minis and MySensors lib I couldn't get less.
Didn't measure with yet another multimeter though...
My battery sensors are working now for about a year and the battery levels are between 65% and 70%.
The sensor furthest from the gateway is at 65% and the 3 others at 70%.
Not bad I think.
