Smart IR temperature sensors integrate sensors and digital circuits to process environmental information without human interference. They combine IR temperature measurement with high-speed digital technologies. The new smart sensors are the smallest available and allow all settings and monitoring to be controlled remotely from a computer. Smart IR sensors use digital electronics for fast response and software for remote setup, diagnostics, and calibration. An example application is using a smart IR sensor to control a space heater by averaging the temperature in its field of view for more accurate heating than just its own temperature. Smart sensors provide benefits like seeing what's in front and adding safety features.
