  • Using the HydraProbe Soil Sensor for Determination of Flood Risk in the New York State Mesonet

    In January 2014, the Department of Homeland Security established the New York State Early Warning Weather Detection System. The centerpiece of the system is the New York State Mesonet, a network of 125 weather stations across the state, with at least one site in every county. Each site measures temperature, humidity, wind speed and direction, pressure, radiation, and soil information (provided by ...

  • Changing Response Times

    Timing is everything for your sensors. A sensor that is too sluggish to respond to quickly changing levels or pressure won’t alert you to dangerous process conditions until it’s too late. And an overly sensitive sensor sees an emergency in every stray reading or transient condition. Neither sensor is effective, in terms of time or money. Sensors ...

  • The Role of Soil Moisture on our Climate, Weather and Global Warming

    Global warming is a topic that has received much attention in the media, especially during the hot days of summer. The process by which carbon dioxide (CO2) in the atmosphere prevents the escape of thermal energy into outer space is known as the greenhouse effect. The higher the carbon dioxide levels in the atmosphere the less thermal energy that can escape thus an increasing ...

  • Sensor data processing for emergency response

    A gap with current Emergency Response (ER) is the lack of real-time information on the status of an incident. Wireless sensor networks have shown great potential in addressing this gap. However, sensor data streams often contain 'noise', thus they are too difficult to be directly interpreted. In addition, sensor data are often meaningless unless it is associated with time and location ...

  • Group method of data handling and neural networks applied in temperature sensors monitoring

    In this work a monitoring system is developed based on the Group Method of Data Handling (GMDH) and Artificial Neural Networks (ANNs) methodologies. GMDH creates non-linear algebraic models for system characterisation and ANN is a massively parallel distributed processor made up of simple processing units called neurons. The monitoring system was applied to the IEA-R1 research reactor at ...

  • How much data is enough data?

    Short answer: it depends on the application and how the data is going to be used.  However, in many ways it boils down to context… For instance, in relation to climate change, if we look at global mean air temperature, it would be very difficult to assess any level of change over time if we did not have a collection of data in a time-series. ...

  • Axetris Sensor Field Test

    The Axetris LGDs were operated continuously for two years. After intensive laboratory testing, they went out into the field in 2015. Axetris was able to test the functionality of its sensors under real-life conditions thanks to the support of the Linth waste incineration plant. The gas concentration measuring devices called laser gas detectors ( ...

  • Alkaline soil, sensible sensor

    Field sensor quickly, accurately identifies soil issues Producers sometimes face challenges that go deep into the soil. They need answers to help the soil, on site. A portable field sensor can accurately measure minerals in soils more easily and efficiently than existing methods. And a research team, including a middle school student and her scientist father, can confirm ...

  • Case Study - Sewer Sensors

    Sewer Sensors Sewer sensors are offered by Solid Applied Technologies for remote level monitoring. The sesnors are ultrasonic, non-contact with no moving parts. The system is equipped with an external battery pack and can operate at a low-power-mode for long term life. The sensors are equipped with embedded GSM cellular modem and act as M2M terminals, transmitting data ...

  • Wireless Sensors for Environmental Compliance

    Untitled Document When no wires are required for power or signal transmission, monitoring devices not only become less costly to own and operate, but they can also be installed ...


  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Forget big data! Collect the right data

    The term big data is everywhere nowadays, but what does it actually mean? According to a definition provided by Google, big data is ‘extremely large data sets that may be analysed computationally to reveal patterns, trends, and associations.’ Sounds great, right? In theory, yes. Through big data, businesses can have a greater overview of their operations than ever before, allowing ...

  • Real-time data in the wild

    Background The South African water resource (DWAF) monitoring network belongs to one of the well organized and managed networks world-wide. Well prepared and maintained measurement sites & stations deliver the data base for the water management in the huge territory of South Africa. One main issue of the online data availability is the data transfer from remote stations to the data ...

  • Optimizing external carbon source addition in domestics wastewater treatment based on online sensoring data and a numerical model

    The removal of total nitrogen in wastewater treatment plants (WWTPs) is often unsatisfactory for a variety of reasons. One possible measure to improve nitrogen removal is the addition of external carbon. However, the amount of carbon addition is directly related to WWTP operation costs, highlighting the importance of accurately determining the amount of external carbon required. The objective ...

  • Data analytics and the materials cycle

    Data has the potential to revolutionise the materials industry, from extraction to processing to commercialisation. But it can only do so with the right mix of technology, skills and strategy. Dr Matt Jones explains. Using data is nothing new, but the rapid increase in data sources and quantity of data collected means getting the most out of it is ever more important. Properly used, data ...

  • Wireless Real-Time Soil Data from Stevens Hydra Probe Soil Sensors Used In Contaminated Soil Cleanup Operation

    Up until the early 1970s when The US Congress passed The Clean Water Act, industrial chemicals and petroleum products were routinely dumped onto the ground or poured down wells. In those days, few people understood groundwater hydrology, and disposing of chemical waste underground seemed like a safe and easy solution. Depending on the chemistry, underground pollution can linger for centuries, ...
