Humidity and Temperature Transmitters
These sensors measure temperature and humidity, then send that information to your PLC or controller to regulate heating and cooling equipment, alarms, and data recorders. Choose a sensor that works with your digital IO-Link or analog 4-20 mA system. Clip it to a DIN rail or mount it to a surface, and use the micro M12 plug to connect the sensor to your controller. These sensors are often installed in enclosures.
Sensors meet American, Canadian, and European safety standards. Rated IP20, they’re designed so fingers can’t reach the electrical parts inside and get shocked. They also meet UL 94 V-0, so if they catch fire, they’ll self-extinguish within 10 seconds and won’t spread the fire by dripping.

Wireless Humidity Transmitters
Use smartphones and tablets to monitor humidity and temperature within your system or facility. Connect these battery-powered transmitters to your smart device via Bluetooth, and receive data to ensure workplace conditions are suitable for processes, inventory, or personnel. Good for preventative maintenance and route-based monitoring, these transmitters let you choose how frequently you receive the data, and they’ll notify your device when humidity and temperature levels go outside of your thresholds. Download the app, set your parameters, and collect data from up to 300 ft. away. Rated IP65, they are protected against dust and washdowns.
Turn your transmitter into a portable monitoring system by attaching a quick coupling (not included). This allows fast, temporary connections for on-the-go measurements in different locations.

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, 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).
