Abstract
Claims
1. A liquid level sensing device with temperature sensing function, comprising: The tube body has an internal space; A reed switch is disposed within the inner space of a tube body, the reed switch being connected to a first wire extending from one end of the tube body and electrically connected to a microcontroller; and a float having a magnet inside, the float being slidably disposed around the periphery of the tube body; characterized in that: a thermistor is further disposed within the inner space of the tube body, the thermistor being connected to a second wire extending from one end of the tube body and electrically connected to the microcontroller; wherein the microcontroller senses the liquid level based on the position of the reed switch sensed when the float moves relative to the tube body on the liquid surface; and wherein the thermistor converts the resistance change generated after sensing the temperature into a voltage signal, and transmits the voltage signal to the microcontroller via the second wire for temperature control.
2. The liquid level sensing device with temperature sensing function as described in claim 1, wherein, With the first wire and the second wire extending out of the tube as the upper end, the reed switch is positioned above the inner space, and the thermistor is positioned below the inner space.
3. The liquid level sensing device with temperature sensing function as described in claim 2, wherein, The reed switch and the thermistor are encapsulated together in the tube.
