Description: We take the sensitive SCP1000 barometric pressure sensor, add the TEMT6000 ambient light sensor, match it with a sensitive SHT15 humidity sensor, and we give you weather over USB! Ok, so it doesn't really predict the weather, but you can immediately tell what the current pressure, humidity, ambient light level, and temperature is. Graphed over time you can watch weather fronts move in and the rain come down.

This new version uses and ATmega328 instead of the ATmega168. Code is interchangeable between the two.

Serial output is a single visible ASCII string at 9600bps.

There is a footprint and switch for 'RF'. This unit can be powered from our large solar cell and data can be transmitted via our BlueSMiRF wireless modem! All you need now is a greenhouse to monitor.

Note: If you plan on using this board in direct sunlight, we suggest purchasing the SCP1000 Gasket as shown below in the related items.
