Abstract
A sensor module comprises a housing and a liquid level sensing module. The housing includes a first passage adapted to permit liquid to flow into an interior of the housing. The first passage defines an air chamber and an air passage in communication with the air chamber. The liquid level sensing module is arranged in the interior of the housing, and includes at least a first part positioned within the air passage. The liquid level sensing module is adapted to sense a characteristic indicative of a liquid level when the liquid flows into the first passage and compresses air in the air passage.
Claims21
A sensor module, comprising:
- a housing including a first passage adapted to permit the flow of liquid into an interior of the housing, the first passage having an air chamber and an air passage in communication with the air chamber, the air passage is parallel to a first part of the air chamber and is in communication with a second part of the air chamber;
- and
- a liquid level sensing module arranged in the interior of the housing and at least partially in the air passage, the liquid level sensing module adapted to sense a characteristic indicative of a liquid level when the liquid flows into the first passage and compresses air in the air passage.
A sensor module, comprising:
- a housing including a first passage adapted to allow liquid to flow into an interior of the housing, the first passage having an air chamber and an air passage in communication with the air chamber;
- a circuit board arranged within the housing;
- a liquid level sensing module connected to the circuit board and arranged at least one of in or on the housing with at least a portion thereof exposed to the air passage;
- a first conductivity sensing module arranged at least one of in or on the housing;
- a turbidity sensing module arranged at least one of in or on the housing;
- and
- a temperature sensing module arranged at least one of in or on the housing.
A sensor module, comprising:
- a housing including a first passage adapted to permit the flow of liquid into an interior of the housing, the first passage having an air chamber and an air passage in communication with the air chamber;
- a liquid level sensing module arranged in the interior of the housing and at least partially in the air passage, the liquid level sensing module adapted to sense a characteristic indicative of a liquid level when the liquid flows into the first passage and compresses air in the air passage;
- and
- a circuit board arranged in the housing and operatively connected to the liquid level sensing module.
A sensor module, comprising:
- a housing including a first passage adapted to permit the flow of liquid into an interior of the housing, the first passage having an air chamber and an air passage in communication with the air chamber, the air chamber is in communication with an inlet of the first passage, and a first slope structure is provided at a connection portion between the air chamber and the inlet, the first passage further comprises a water blocking component arranged in the air chamber and extending toward the inlet of the first passage, the water blocking component extending within the air chamber to a height greater than an upper edge of the inlet of the first passage, the water blocking component defines:
- one or more protrusion structures extending in a direction toward the inlet of the first passage;
- or
- a second slope structure;
- and
- a liquid level sensing module arranged in the interior of the housing and at least partially in the air passage, the liquid level sensing module adapted to sense a characteristic indicative of a liquid level when the liquid flows into the first passage and compresses air in the air passage.
