The Davis Wireless Temperature/Humidity Station includes a temperature/humidity sensor, transmitter, and radiation shield.
The Davis Temperature/Humidity Station can collect data from up to 8 stations. The data can be viewed using the Vantage Pro2 console/receiver or via the Weather Envoy or WeatherLink software. The station is battery powered, and lasts up to one year using a lithium battery under normal conditions. The station is compatible with Vantage Pro2 only.

Escherichia coli (E. coli) in stormwater runoff is a perennial problem in South Dakota—and in many other places in the US and around the world. Especially in places where drought makes every drop of rainfall count, it's crucial to remove harmful bacteria such as E. coli from stormwater. Researchers from the South Dakota State University (SDSU) Department of Civil and Environmental Engineering may have a promising—and cost-efficient—new solution to this problem: steel chips.
After the storm
A good rain can make it seem like everything is fresh and clean—in part because stormwater washes dirt and grime that covers streets down into sewer systems. That includes animal and human waste, and E. coli bacteria.Read More
Harmful algal blooms (HABs) and the toxins they produce, threaten drinking water safety worldwide, and here in the US, we are becoming more aware of the issue as HABs are reported across the country. Microcystins, the most common toxins arising from HABs, can put animals and humans at risk. Human reactions to microcystins include mild skin rash, respiratory illness, kidney or liver damage and even death.
If you use a water-filter pitcher to ensure harmful microcystins aren't present in your drinking water, recent research has both good news and bad news for you. First, the bad news: these water-filter pitchers vary substantially in how effectively they can remove harmful contaminants.Read More
Imagine fleets of compact, self-propelling robots quietly making their way through the world's oceans, surveilling marine life and monitoring conditions, each one moving without a power supply or even an engine. It may sound like science fiction, but thanks to a team of researchers from ETH Zurich and Caltech led by Professor Kristina Shea , this new concept for self-propelling, swimming robots that exploit in-water temperature fluctuations to move, has now undergone a successful proof-of-concept study.
“We had already developed 4D printed deployable structures that use the combination of shape memory polymer strips and tunable, bi-stable joints to reconfigure themselves from flat structures into different forms,” explains Professor Shea.Read More
