Environmental-Monitoring Modules for Development Boards
Keep equipment running and working conditions safe—these modules add air quality tracker capabilities to your development board. Each module gathers data on air conditions, ranging from temperature and humidity to carbon dioxide or volatile organic compound (VOC) levels. These modules easily connect to boards and other components with Qwiic cords or by soldering.
Modules with a temperature, humidity, and air quality sensor help you make sure the air is healthy in your facility. They directly measure the amount of carbon dioxide in the air.
Modules with a temperature, humidity, air quality, and barometer sensor give you the most comprehensive picture of air conditions in your facility. They directly measure the amount of VOCs and give you an estimated measurement of carbon dioxide based on VOC levels. They monitor air quality using Germany’s Air Quality Index (AQI).

Acoustic Imaging Gas Leak Detectors
Locate leaks up to 10 times faster than traditional leak-detecting methods. These detectors use 124 microphones to determine the precise location and size of leaks in compressed air and specific gas systems. The screen displays a high-resolution acoustic image that’s overlaid on a digital live shot of your facility to help you visualize the leak. It also displays analytics related to the leak, such as the rate and the potential cost savings of patching your system. You can capture the on-screen view through photos and video to review later. With a built-in flashlight, they remain accurate even in low-light spaces. Light enough to carry with one hand, you can bring these detectors on the go. A 650 ft. range means you can use them from one end of your facility to another, or to detect in hard-to-reach systems.
Connect the detector to your computer using Wi-Fi or the included USB cable to quickly transfer collected data.

Infrared Refrigerant Leak Detectors

Three times more sensitive than standard refrigerant detectors, these infrared detectors can identify leaks as small as 0.03 oz. per year. They have an easy-to-read LCD screen that displays the concentration of gas in parts per million (PPM). When a leak is detected, an indicator lights up and the device emits a sound. Check for leaks in hard-to-reach areas using the built-in flexible probe. Use them to detect a variety of halogenated refrigerants.
Product regulations restrict sales to the listed areas.
Add a sensor to detect carbon dioxide or flammable refrigerants.
