Abstract:
A temperature and humidity sensor module heat drying structure used in an electrical product is disclosed to include a temperature and humidity sensor, a heating element and a micro control unit. When the humidity value detected by the temperature and humidity sensor surpasses a predetermined reference value, the micro control unit controls the heating element to heat the temperature and humidity sensor, evaporating water from the surface of the temperature and humidity sensor. After a period of time, when the humidity value detected by the temperature and humidity sensor is lower than the predetermined reference value, the heating operation is stopped, keeping the temperature and humidity sensor in optimal working condition.

Abstract:
A temperature and humidity sensor module sensing method for enabling a temperature and humidity sensor in an electric product to provide the detected humidity message to a micro control unit for determination. According to the characteristic curve of a known humidity sensor, the micro control unit determines that the humidity value rising slope exceeds a predetermined rising slope for a specific period of time, or the relative humidity rises a predetermined percentage for a specified period of time, or a high humidity limit continues for a specific period of time, indicating that the surface of the temperature and humidity sensor is attached or condensed with water molecules. Then, the micro control unit controls the heating element to heat-dry the temperature and humidity sensor, keeping the temperature and humidity sensor in the optimal working condition.
Abstract:
A water quality sensor includes a housing including a light transmissive bucket mounted in an electrical washing appliance and a light transmissive inner barrel mounted in the bucket, an actuation module mounted in the inner barrel for detecting a water quality of a washing solution in the electrical washing appliance. Thus, if the bucket is cracked during manufacturing or due to a collision, the actuation module can still be well protected by the inner barrel, so that the washing solution in the electrical washing machine does not directly flow into and contact with the actuation module to cause an accidental short circuit of the circuit substrate of the actuation module, improving the water resistance and service life of the water quality sensor.
Abstract:
A conductivity measurement method for measuring the conductivity of a fluid in a washing chamber in an electrical washing machine using a water quality sensor consisting of a control unit and first and second conductors by alternatively changing the electric potential of the first and second conductors and repeatedly measuring the conductivity of the fluid in the washing chamber between the first and second conductors upon each electric potential alternation.
Abstract:
An optical water quality sensor includes a holder base having a first light-transmitting portion and a second light-transmitting portion extending in the same direction, a first receiving groove and a second receiving groove respectively extending into the first light-transmitting portion and the second light-transmitting portion and a first light-condensing side and a second light-condensing side respectively located on the inner sides of the first light-transmitting portion and the second light-transmitting portion, and a sensor module with a circuit board assembled in the accommodating space. The circuit board has a first arm plate and a second arm plate respectively inserted into the first receiving groove and the second receiving groove, and a light emitter and a light receiver respectively located on the first arm plate and the second arm plate to face the first light-condensing side and the second light-condensing side.
