AcuRite Optimus Weather Sensors feature a modular design that allows for replacing the Temperature and Humidity Sensor, should it cease to function. If you're experiencing temperature or humidity reading issues, such as no change in readings, the temperature and humidity sensor may be worn out and will require replacement.

This replacement sensor can help if you are experiencing the following issues:

• Temperature stuck on -40° or 158° Fahrenheit
• Humidity stuck on 1% or 99%
• Inconsistent temperature or humidity readings
