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 ...

In this fire alarm circuit, a thermistor works as the heat sensor. When temperature increases, its resistance decreases, and vice versa. At normal temperature, the resistance of the Thermistor (TH1) ...

The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...
