Wireless Environmental Sensor

After about 100 days using the Moteino to log temperatures and humidity I have started a new project. Actually the batteries are still going after 100 days (Well, almost). The new project will again use Moteinos, but this time I will upgrade the whole thing. In addition to temperature and humidity logging, I will add a display and a barometric pressure sensor. I will write the code so it's easy to add other sensors, like rain, flood, plant humidity, light conditions etc.

Easy code equals easy assembly. I can then create a flood warning device without a display, using the same code as the devices with a display. On the display I want to show the current temperature, humidity and air pressure. Along with this, I want to show the battery voltage.

Battery life is essential. I want the sensors to run for months without changing the batteries. The display uses about 0.5mA when "dead". "Dead" means when it shows static content without light.
