Temperature sensors are devices that detect and then quantify the temperature of their environment. Glass tube thermometers are a simple example. Modern temperature sensors, however, are electronic devices that convert the raw environmental input (the temperature reading) into electronic data, which can then be transmitted to a remote electronic display or interpreted by software and building automation systems.
The purpose of a temperature sensor is to record, monitor, and trend temperature changes. Sensors can also be used to trigger other systems in response to set temperature parameters. For example, activating heating or cooling systems or adjusting fan speeds or outside ventilation. These functions make temperature sensors a cornerstone of modern HVAC and building management systems.
Humidity is often associated with hot weather and can be confused with temperature. After all, hot, humid air makes for an uncomfortable indoor environment. However, humidity is separate from temperature.
Both types of sensors can help to improve IAQ, since both temperature and humidity will impact the occupants’ overall level of comfort. They protect against different threats, though. Watching humidity can help you to prevent mold and mildew growth or to maintain environments sensitive to wet/dry air (like libraries, zoos, laboratories, or print shops). Temperature is more important for maintaining cold storage, preventing overheating in data centers, and other applications where heat or cold can cause trouble.
Ideally, your temperature sensor will also include a humidity sensor, so that you can track both!
Temperature sensors are used to measure temperature in many different applications and industries. Here are some examples of industries and applications that make use of temperature sensors:
There are a wide variety of temperature sensor types, each used for different purposes and temperature ranges. Here’s a small list of some examples:
Temperature sensing technology has been around for a long time and has been perfected to impressive levels of accuracy and specificity. Not only that, but the technology needed to create an extremely reliable temperature sensor is highly affordable. There’s little reason to overlook the installation of temperature sensors in our smart modern buildings where these cost-effective little workhorses can make a huge difference.
People can sense ambient temperatures on their own, and simply rely on their level of comfort to adjust indoor temperatures. However, we’re likely to only realize the temperature is suboptimal once it’s well off the mark. With a temperature sensor, you have a device that’s always watching and this makes it easier to react quickly when temperatures fall outside their optimal range. With automation enabled, it’s even more convenient — you don’t need to do anything because the system corrects itself.
Linearity is a measure of how much a sensor’s output deviates from the input parameter that is being sensed. More linearity makes it easier to calibrate and minimize uncertainty in its output scaling.
Hysteresis is a measure of how much lag there is between changes in the input (the temperature) and the output (the sensor’s reading). A low level of hysteresis would mean that the sensor is reading temperature changes without much delay, as close to real-time as possible.
High-quality temperature sensors are precise, with excellent linearity and low levels of hysteresis. The sensor’s detected output closely matches the real temperature input and reflects any changes almost immediately.
When selecting a temperature sensor for use, for whatever reason, you should take the following into consideration:
