    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.

    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.

    Wireless Temperature and Humidity Transmitters

    Image of ProductInUse. Front orientation. Temperature and Humidity Transmitters. Wireless Temperature and 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.

    Detector

    Detector (Bottom)

    Keep an eye on leaks, overflow, and temperature changes near your equipment, even when you’re offsite. These detectors connect to your Wi-Fi to send alerts about moisture, temperature, and humidity to your smartphone or tablet. Place them near tanks and tubs to watch for overflow, or near sump pumps and pipe lines to monitor temperatures and prevent frozen pipes. When water touches one of the sensors on the detector, a buzzer also goes off, alerting anyone nearby. Rated IP44, these detectors are protected from objects larger than 1mm, such as wires, and from water splashing in any direction.
    Download an app onto your smart device to program temperature and humidity ranges and set up alerts. You can also create reports that show changes in temperature and humidity over time.
    To extend the area they monitor, these detectors come with a detachable cable sensor that senses moisture along its entire surface. Swap in replacement cable sensors for worn sensors, or link several together to wrap around large equipment or trace the path of a pipe. Extend them up to 500 feet from detectors.

    Remote-Sensing Enclosure Space Heaters

    A sensor attached to the heater might signal that it’s warm enough near the heater, while other parts of the enclosure are still cold. Moving the sensor away from the heater helps you keep electronics warm and dry, anywhere in the enclosure. For even heat, a fan blows upward to circulate warm air.
    Choose a heater that clips to DIN rail or one that mounts to the bottom of your enclosure. Add a sensor (sold separately) that reaches the part of your enclosure you need to keep warm.
    Heaters meet American, Canadian, and European safety standards. They also meet UL 94 V-0, so if they catch fire, they self-extinguish within 10 seconds and won’t spread the fire by dripping.

    Control, monitor, and program your HVAC system from anywhere. These thermostats connect to a Wi-Fi network, so you can use a computer, tablet, or smartphone to view and adjust settings. You can also lock the settings to prevent accidental changes or tampering in public areas. They control low-voltage, multistage HVAC systems that have up to three heating and cooling speeds. Use them to set an individual program for each day of the week.
    Temperature Control Location Sensing—Location-sensing thermostats connect to an app that tracks the location of your mobile device. They can automatically adjust the temperature based on your distance from the thermostat. Use the app to send push notifications for service reminders, unexpected temperature changes, and interruptions to the Wi-Fi connection.
    Humidity/Temperature Sensor—Thermostats with a humidity/temperature sensor also detect motion. Place the remote sensor in a room or enclosure to maintain a consistent climate. To help save energy, they can raise or lower the temperature when no motion is detected.

    Check temperature, relative humidity, atmospheric pressure, and time with a single barometer.
    Remote-Reading 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.
    525,600 Readings—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).

    Fixed Actuation Point

    Adjustable Actuation

    Point

    Reduce the humidity in your enclosure to prevent condensation that can cause corrosion and short circuits. These humidistats switch your heater on when the enclosure reaches the relative humidity setting. Once the humidity falls by 5%, the heater switches off. To install, clip humidistats to a DIN rail.
    CSA Certified, CSA-US Certified, CE Marked, and VDE Certified, these humidistats meet American, Canadian, and European safety standards. They also meet UL 94 V-0, so if they catch fire, they self-extinguish within 10 seconds and won’t spread the fire by dripping.
    Fixed Actuation Point—Fixed humidistats work for most applications. They keep humidity below 65%, which is when condensation is most likely to form. Since they aren’t adjustable, the humidity setting can’t be tampered with or accidentally changed.
    Adjustable Actuation Point—For critical components, use adjustable humidistats to set the relative humidity you need in your enclosure. Use a lower humidity setting in damp environments and places with frequent temperature changes. Condensation is more likely in these situations.
