Climate ModuleThe Climate Module integrates 4 environmental sensors - temperature, humidity, light intensity and atmospheric pressure. All sensors are digital, feature low-power operating modes and connected by using the I²C bus. It is a great product for environmental monitoring, weather stations, etc.

You can use the Climate Module altogether with the Mini Battery Module and the Core Module to create a very compact wireless environmental sensor.
