A split system heat pump's defrost sensor is used to detect ice buildup on the heat pump's outdoor coil. When ice builds up on the coil, it reduces the heat pump's ability to transfer heat, which can ...

This fire sensor circuit exploits the temperature sensing property of an ordinary signal diode IN 34 to detect heat from fire. At the moment it senses heat, a loud alarm simulating that of Fire ...

Why heat flux (flow) is an important thermal parameter. How researchers have developed an innovative heat-flux sensor. Details on the performance of this sensor in flat and curved situations. We know ...
