Details

Overview
The Lufft WS401 Multi-Parameter Weather Sensor offers a cost-effective, compact alternative for the acquisition of a variety of measurement parameters on land- and buoy-based weather stations. Depending on the model, each sensor will measure a different combination of weather parameters to meet a wide variety of applications.

Air Temperature & Humidity
Temperature is measured using a highly accurate NTC-resistor, while humidity is measured using a capacitive humidity sensor. Both sensors are located in a ventilated radiation shield to reduce the effects of solar radiation.

Pressure
Absolute air pressure is measured using a built-in MEMS sensor. The relative air pressure referenced to sea level is calculated using the barometric formula with the aid of the local altitude, which is user-configurable on the equipment.

Precipitation
Precipitation is measured using an integrated tipping bucket rain gauge. The flexible tipping bucket can be configured for 0.2mm or 0.5mm rainfall resolution.

Lufft WS-Series Weather Stations: A history of weather monitoring translates to high quality weather sensing options

Gotthilf Lufft started building mechanical weather sensors in 1881. “They really began by measuring temperature and humidity in the most basic sense,” said Ann Pattison, Lufft USA product manager. More than 130 years later, the company is still building weather monitoring technology. For their most recent rendition of weather stations, Lufft engineers traded mechanical dials and horse hair for ultrasonic transducers and pyrometers to create a line of electronic all-in-one weather stations called the WS-Series. The systems have a modular formula that can be tailored to customer’s applications. In fact, many of the ready-made combinations Lufft offers, like a weather station with built-in tipping bucket rain gauge, were inspired by customers.

Delaware Environmental Observing System detects rare tornado in state

A University of Delaware monitoring network picked up a tornado that touched down in Newark on June 10, according to a release . Tornadoes are rare in the state, but sensors were there to capture it. The Delaware Environmental Observing System , which supplies data to the National Weather Service, charted the tornado with winds of 65 to 85 mph. The observing system also measured the heavy rain that accompanied the tornado. Experts say a low-pressure system and cold front in the Ohio Valley met with warm air in Delaware, which set off the churning clouds that ultimately generated the tornado. The tornado was picked up by a weather station nearly a half mile away, which measured wind speeds at 20 mph.

USGS weather station network monitors Arctic Alaska's climate

When the U.S. Geological Survey began building their climate and permafrost monitoring network in Arctic Alaska in 1998, there wasn't much precedent for how to build the infrastructure for the instruments in the region's unforgiving environment. That meant the scientists had to learn the particulars on the fly. For example: On the great expanse of flat, barren tundra, a weather station sticks out like a sore thumb to a curious grizzly bear. "The initial stations were pretty fragile," said Frank Urban, a geologist with the USGS Geosciences and Environmental Change Science Center. "So the bear and those stations--the bear won every single time without any problem.
