The Onset HOBO Weather Station can record up to 15 different outdoor environomental parameters. Temperature, Humidity, Barometric Pressure, Light, Rain Fall, Leaf Wetness and Wind Sensors are available (sold separately) for easy plug-in and automatic detection by the logger. The weather station features multiple start modes, 100 meter maximum combined sensor range and input adapters for pulse, dc voltage and 4-20mA.
