Throttle position sensor - Monitors the throttle valve position (which determines how much air goes into the engine) so the ECU can respond quickly to changes, increasing or decreasing the fuel rate as necessary. It is a non-contact type temperature. For the most accurate readings the thermometer should be the same temperature of the ambient or surrounding temperature. Differences in the ear canal size or shape can make this type of thermometer less accurate. Heart Rate and Core Temperature. This sensor measures the. This inbuilt sensor technology helps the user to measure body or object temperature for free. They lose more body heat than they produce, so their internal systems must work much harder to maintain steady body temperature. A ZHF sensor insulates the skin locally, ensuring the skin surface is heated to deep body temperature and creating a region of zero heat flow from the body core to the skin (Fox et al 1973). The intake air temperature sensor or IAT sensor has the core function of monitoring the temperature of the air that is entering the engine of your vehicle.
