ITS400
Developed by Intel Research lab and licensed to Crossbow, the ITS400 sensor board is designed to interface with the Imote2 platform. It contains a three-axis accelerometer, an advanced temperature/humidity sensor, a light sensor and a 4 channel A/D converter. The ITS400 allows stacking with other extension boards.

This versatile sensor board provides multiple sensing capabilities for the Imote2 in a wide variety of applications ranging from environmental monitoring to capturing vibration.
