@Petjepet I Know, thank

on board as I did your chart

Thank

@Petjepet said:

On the green wire (light sensor?) you measure on ground where I guess you should measure between the resistor and the sensor.

Is the same

voltage divider

New fritzing

I have two questions?

1. voltage divider for more 5 v (battery voltage 12-13 volts)
2. I use a auto phone charger for step down (12v --> 5 V) - warmers if I close in a box?

Thank

Fritzing File!!!!

@Dombo71 look a fritzing schematic

I purchased a solar kit

Solar Panel
battery 12v
landstar solar charge controller

I want to insert into Arduino in output of charge controller (I have 12 volts)

to lower the voltage can I use a mobile charger Car 1 Ah

do you heat so much?

Thank

@Salmoides Good Project!!!!!

Merry Christmas

@cdrum I tried with many arduino nano purchased on ebay but I could not connect on vera.

Try with gateway Ethernet !!!

@Anticimex very nice work.

I have created a bridge for mysensors and openenergymonitor, Openenrgymonitor work whith respberry and emoncms. Whit this way I can save the data of sensor data mysensors.

Node 7 is bridge to mysensors and RFM12B radio.
radio transmission is point to point!!!

@Terence-Faul which controller do you have?

how do you make these pcb so beautiful?

my pcb are full of wires !!!

there is no problem to put 4 relays.
you just feed a separate power!!!

@Heinz nice project !!!

I use VERA, I did a My Relay Module, if I push button or send command on vera, i have alwais a state of socket.

with your system, you can know the status of the socket?

from the photo, I dont' see a button to turn on the socket !!!! Only via remote control!!!

gigi

@axillent
very very cool!!

@ServiceXp said:

I just can't believe that the display, rfm12b and NRF24 on the same 3.3v rail is under 50ma,... not too mention the other stuff on it.. You could try disconnecting everything except the NRF24 and see what happens?

I can't even get my NRF24's to work with the shop's listed boost with the Pro Mini attached without a 'massive' capacitor.

I tried to put a separate power supply.

General supply 5V 2 Amps.

I do not have the controller and I put two arduino nano for 3.3 volts

after 2 hours the system crashes.

if I put only one of the two radio system is fine.

I tried it with a standalone with two radio but without a monitor and the system works perfectly!!!

I have to put other capacitors?

Thank

@gregl said:

haha..cool.

I bought an airwik like clone the other day, but i want to hack in a pir sensor so that it only squirts the airfreshner when movement is detected and use mysensors to count how many squirts it does....so as to know when to replace can.

now i think about it, i should have bought one with a pir inbuilt like yours...oh well!

watch this photo!!!

Hay!!!

This is MyAirwik Sensor

Voltage measured!!!

On Vera lite!!!

Battery Version!!!!!

Relay on

Only 3.3 volt

I do not know if I measured correctly, and my instrument is accurate !!!!!
