We often hear the phrase "you're too sensitive" applied to people. I'm not sure that's really a true assessment; possibly the person saying it is not sensitive enough when it comes to other's feelings. With temperature sensors, "too sensitive" may have real meaning.
We may always want things to happen fast, but if they happen too fast sometimes the speed will lead to snap judgments or actions when waiting a few seconds will reveal that nothing unusual is really happening. Environmental monitoring systems that provide alerting functions can sometimes be too sensitive when it comes to changes in temperature. For example, if a sensor is reading room temperature in a vacation home and someone leaves the door open on a cold day as they unload the week's grocery order, an alert can be sent out when no action is required. The sensor may be too close to the door, so moving it will help. In some cases moving the sensor may not be possible, so slowing down the response will be needed.
Our latest White Paper discusses considerations of sensor sensitivity when selecting and placing temperature sensors. The White Paper can be viewed in our Resources section, or by clicking on this link. Link to Sensor Sensitivity White Paper
