  • CO2 vs. VOC Sensors for IAQ - What`s the Difference

    People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...

  • Why are waste operations installing on-board scales?

    Given the rising cost of operating waste collection vehicles, it is becoming more important to evaluate the use of on-board weighing systems to reduce operating costs, meet new safety standards and improve fleet efficiency. Electronic on-board scales are not new. They were introduced more than 30 years ago into trucking applications where monitoring gross vehicle or payload weight was ...

  • Area Monitoring: Diffusion Sampling

    Indoor and outdoor gas hazards that exist in open areas are usually monitored using diffusion-type sensors. A diffusion sensor has no active sample-drawing system; diffusion sensors rely on the ambient air movement and pressure to deliver the sample to the sensing element. Diffusion-type sensors are a reliable and cost-effective way to monitor open area gas hazards. When installing diffusion ...

  • How clean is your local air?

    Few people know how clean the air is where they live, work, exercise or where their children go to school. Although air quality can be shown to vary significantly over short distances, air pollution is generally measured using a small number of large, expensive and high quality monitoring stations. The equipment used in these stations is very accurate and complies with measurement standards but ...

  • Smart cities risk reputation with poor air quality data

    The team at AQMesh continue to receive many enquiries from smart city initiatives and are concerned that integrators risk undermining entire projects by distributing meaningless or misleading air quality information. “Many of the people I speak to are used to dealing with sensors that are easy to ‘plug and play’ and expect to be able to do the same with air quality sensors. This ...

  • What is Modbus?

    Modbus is a data transmission protocol developed by Modicon in 1979 for industrial control applications. It uses a master-slave architecture, where one device is in charge and requests information from multiple (slave) devices. Modbus is a simple command and control protocol that has been adapted to a number of media including TCP/IP, SMS, and wireless transceivers. Modbus is widely used for ...

  • The New Generation of the UMB Config Tool: Discover ConfigTool .NET

    It is hard to imagine that until recently I had nothing to do with apps and graphical programming, but I had been satisfied with my bits and bytes. They are the innermost of every computer. When I was programming the new ConfigTool with Windows and Android programming, I quickly took pleasure on it and teached it myself. This is partly due ...

  • The Fundamentals of the Air Sampler Calibration-Verification Process

    INTRODUCTION The calibration of an air sampling instrument using a reference air flow calibrator requires attention to scientific detail in order to establish that the instrument’s reported values are correctly stated and valid under the actual operating conditions of the air sampling instrument. DEFINITIONS For the purposes of this ...

  • Indoor Air Quality Sensor Testing for Heating, Ventilation and Air Conditioning (HVAC)

    What is Heating, Ventilation and Air Conditioning (HVAC) and why is an Air Quality Sensor needed? Heating, ventilation and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort which aims to provide optimal wellbeing, safety and cost efficiency of those inhaling the air. This cannot be achieved without indoor air quality testing using an air quality ...

  • Does your availability of Data Trend Toward Saving Money?

    A case must be made for changing how buildings operate, so Cloud connectivity for sensors is essential. It is becoming common that large monitors are placed in the common area to show building operations, energy consumption, calculated Carbon Footprint, recycling productivity, and waste reduction. It is now as if we are demonstrating an Internet of Things, an IAQ sensor system that will validate ...

  • Selecting an Airborne Particle Counter: Types of Monitoring (Series Part 2 of 4)

    Frequent or Continuous? Frequent Monitoring To demonstrate compliance to ISO, frequent monitoring requires sampling at specified time intervals not exceeding 60 minutes during operation. Manifold systems are the least expensive solution and usually installed during the cleanroom construction process. Standalone particle counters may be installed at any time. A ...

  • Selecting an Airborne Particle Counter: Number of Monitoring Locations (Series Part 3 of 4)

    After choosing the monitoring method, determine how many monitoring locations or particle counters you need. If the area of your cleanroom is 1,000 m2 or less, use Table A.1 provided in ISO 14644-1:2015. If your area is greater than 1,000 m2, first divide the cleanroom area (in m2) by 1,000. Then multiply this number by 27. Remember that this is the minimum ...

  • Use of In-Line Inaflatable Dams for CSO Control

    ABSTRACTThe Detroit Water and Sewerage Department (DWSD) recently installed thirteen (13) in-line insystem storage devices (ISDs) in large combined sewers in Dearborn, Detroit, Hamtramck and Highland Park, Michigan. The ISDs are designed to store combined sewage in the sewers during wet weather, especially during smaller storms that do not utilize the full transport capacity of the sewers. The ...

  • Application of nanocrystalline metal oxide gas sensors for air quality monitoring

    Increasing concern regarding health effects caused by air pollution, together with the limited spatial resolution achievable with conventional monitoring stations, have driven efforts to develop inexpensive metal oxide gas sensors for air quality measurements.
