Small Printed Circuit Board (PCB) for wireless and battery powered sensor nodes. The board has one sensor input (Signal A0/D10 on Pin 13) and is powered with 2 AA batteries. Additional proto space with solder pads provides room for small circuits.

Depending on the sensor the sensor input is configured as analoge (A0) or digital input (D10).

The following sensors has been used with the sensor node board:

• NTC (Temperatur Sensor)

• 18DS20 (1-Wire Temperature Sensor)

• LDR (Light Sensor)

• Hall Sensor

• Reed Contact/Switch

• Soil Moisture Sensor with Nails

• PIR Sensor (with internal Power Booster)

Code

In order to use Arduino Code with the board you need to install the ATtiny core for Arduino and a RFM12B Library called JeeLib.

The JeeLib Library is the perfect solution for simple wireless applications. This universal library provides many examples of wireless applications with the RFM12B.
