After many years I’ve re-discovered electronics as a hobby, thanks to the JeeLabs and Arduino communities.

I’m setting up a small electronics lab with some basic equipment like the Rigol DS1052E oscilloscope (approx. 300 Euros; I “upgraded” mine to the DS1102E firmware to increase the scope’s bandwidth to 100MHz).

One of my first projects is building a Wireless Sensor Network (WSN) to measure humidity, temperature, brightness and motion in several locations at home. The necessary hardware is depicted on the right.

I’ve added a simple resistor ladder network to one of the analog inputs, allowing me to measure battery voltage; these units are [...]

JeeLabs offers a low-power, Arduino-compatible board called the “JeeNode“. These are ideally suited for building your own Wireless Sensor Network, for example in combination with the Room Board.

There are several ways to plug a Room Board into the JeeNode. The pictures below should help you verify the correct “Port” settings for each configuration:
