Desktop Multifunction Barometers
Check temperature, relative humidity, atmospheric pressure, and time with a single barometer.
Remote-reading barometers wirelessly monitor outdoor temperatures and relative humidity as well as indoor conditions. They'll transmit readings from up to 200 feet away.
Direct-reading barometers that hold 525,600 readings store about two years’ worth of data. They’re often used in laboratories because they continuously monitor conditions, so you can track changes over time. Use their USB-A connection to transfer stored data to your PC with a USB cord (not included).

Wireless Weather Stations
Monitor nine different weather conditions up to 1,000 feet away. The outdoor weather sensor measures outdoor temperature, humidity, wind speed and direction, rainfall rate, total rainfall, barometric pressure, heat index, wind chill, and dew point. It wirelessly transmits readings to the console by radio signal. Console has built-in sensors to measure indoor temperature and humidity. Console can be placed on a desk or mounted to a wall. They cannot be sold to the listed areas due to product registration requirements.

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 barometer sensor are often used as part of an automated system that runs equipment based on the weather. For instance, you can use them in a system that will turn on a humidifier if humidity dips below a certain level.
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).

Multifunction Smartwatches
Keep your phone in your pocket and your hands free—these smartwatches perform a variety of functions on your wrist. They connect to Apple and Android phones via Bluetooth, informing you when calls, texts, and other notifications arrive. Designed for harsh environments and rugged use, they meet military standards for resistance to hot and cold temperatures, shock, splashes, and submersion in up to 100 meters of water. These watches have a compass and GPS for tasks such as navigation, tracking and saving location coordinates, and calculating the area of a location by walking the perimeter. With weather and elevation monitoring, you can set the rate of barometric pressure change that will trigger a storm alert. These watches track health and fitness metrics over time, including heart rate, blood oxygen levels, and exercise. They have a solar battery in addition to a rechargeable lithium-ion one to extend the time between plug-in charging.
