Arduino Duemilanove

The Arduino Duemilanove is a microcontroller board based on the ATmega328 AVR microcontroller. It has 20 digital input/output pins (of which 6 can be used as PWM outputs and 6 can be used as analog inputs), a 16 MHz crystal oscillator, a USB connection, a power jack, an in-circuit system programming (ICSP) header, and a reset button. The Arduino has an extensive support community, which makes it a very easy way to get started working with embedded electronics.

USB Weather Board

This USB weather board from SparkFun is fitted with a SCP1000 absolute pressure (and temperature) sensor, a SHT15 humidity sensor, and a TEMT6000 ambient light sensor. This allows the on-board ATmega8 to deliver pressure, humidity, temperature, and light level via USB. Serial output is a single ASCII string at 9600bps, 8N1, at 1 reading per second.

SCP1000 Absolute Pressure Sensor Carrier

SparkFun’s carrier board for the SCP1000-D01 absolute pressure (and temperature) sensor allows pressure measurements with 17-bit (1.5 Pa) resolution over a range of 30 to 120 kPa, which lets it work well as part of a barometer or altimeter. Both the pressure sensor and built-in thermometer can be read via the SPI lines brought out by the carrier board to a 0.1" header.
