Tip #2: Use Your Sensors Inside or Outside

In the design process of Notion Sensors, we considered all the harsh elements and extreme conditions that a sensor may be subject to if installed outdoors. Sensors are resistant the the elements, but their performance may be affected if exposed. Notion Sensors are rated from 0 Degrees Fahrenheit up to 175 Degrees F (-17 C to 80 C).
