    This project uses an Arduino pro mini 3.3v 8mhz. The power and pin 13 LEDs have been desoldered to save battery life. The battery used is a 18650 lithium and a single 18650 battery bank.

    XAMPP server: http://www.jbcse.com/weather-graph.php

    All sensors and the transceiver powered through an IRL520 mosfet. The Jeelib power library is used to make the arduino sleep for about 10 seconds which uses about 1 mA. Measuring takes about 2 seconds and uses 5 mA.

    Sensors used: DHT22, BMP185, SI1145
    Transceiver used: NRF24L01+

        @jesse How do you make a difference between visible and IR light ?

        I've made a bit the same, I'm now working on soil mosture+temp and leaf moisture. The solar flare is missing to have a pro weather station...

        z-wave - Vera -> Domoticz
        rfx - Domoticz <- MyDomoAtHome <- Imperihome
        mysensors -> mysensors-gw -> Domoticz

          @epierre The SI1145 can measure IR, visible, and UV light: https://learn.adafruit.com/adafruit-si1145-breakout-board-uv-ir-visible-sensor/overview

            This is a very nice sensor indeed! Didn't know about it.
            Think I'm gonna sample some.

              Very interesting projekt. Can you show your sketch? I try to build nearly the same, but have some problems with SI1145.
