Environmental and air quality sensors

Environmental and air quality sensors

With environmental conditions having a major impact on health and well-being, environmental monitoring is becoming more important. So much so that the EU has introduced the Clean Air Act, to follow air pollution standards it expects all member states to meet in order to protect the natural environment from harmful contaminants that have a detrimental effect if inhaled or absorbed through the skin.


    Specialist sensor range

    Our specialist range covers all key parameters for any environment, but to help solve more complex challenges for your application, we can design and build a complete solution to your needs with customer-specific combinations and custom-designed solutions along with wireless connectivity.

    As a complete solutions provider with years of expertise in applying and developing environmental sensor solutions for both indoor and harsh environments, not only can we provide the best sensor technology available, but we can also support your design, integration and development to create ground-breaking applications whilst focussing on what’s important for Air Quality Monitoring (AQM) applications, such as:

    • Accuracy and stability – The maximum difference between the actual and indicated value needs to be minimal to ensure you are delivered accurate readings of what you are monitoring
    • Low power consumption – A long life span is key for an environmental sensor that’s applied to a device that needs to last or is remote. Constant, consistent readings over a long period with minimal change in the readings after time and usage
    • Small size – Their decrease in size means they can be easily placed in many more locations measuring different attributes and opens up more portable and wearable device opportunities
    • Custom solutions – From combining several different gas sensing solutions to a full custom design involving wireless connectivity, a fully packaged finished product tailored to your specific application requirements

    Airflow sensors

    Used for measuring the flow of indoor air quality, gas or fluid, usually within a flow meter. We have a range of advanced digital and analogue airflow sensors that provide enhanced reliability, high accuracy, repeatability, and fast responses, across a variety of high sensitivity flow ranges in either compensated or non-compensated options. We also offer the ability to customise sensor options to meet specific or complex application requirements.

    Perfect across potential applications include heating, ventilation and air conditioning (HVAC), gas metering, and medical equipment.

    Humidity sensors

    Humidity sensors


    Offering some of the worlds most advanced solutions for both digital and analogue humidity sensors for virtually any application.

    Bringing industry-leading stability and reliability, with wide operating ranges, small sizes and low power/ cost solutions as well as combined and custom package options.


    Dust and particle sensors

    Dust and particle sensors

    Partnering with the most innovative suppliers of dust & particle sensors, enables us to bring both standard and fully customisable technologies to our range. These sensors will enable fast, wireless deployment of data-critical industrial and commercial sensor solutions that are cost-effective with superior performance and reliability, all with the aim to drive better air-quality standards.

    Covering both indoor and outdoor sensors with the latest light scattering technologies able to detect particle concentration between 0.3~10µm using real-time output. They are some of the most accurate, sensitive and quick response sensors on the market in compact sizes for easy installation and suited many different applications.
