There are several sensors for lg, including the following:
Fridge temperature sensors
The fridge temperature sensor controls and monitors the temperature inside the refrigerator. It does this by sending the temperature readings to the main control board. When the temperature is too high or low, the sensor triggers the appropriate actions, such as running the compressor or turning on the fan. It ensures that the temperature remains within the set limits. The sensor has a bulb filled with liquid that expands and contracts based on temperature changes. The physical changes of the liquid in the bulb are what trigger switches and controls in the refrigerator.
Smart refrigerators
Smart refrigerators have temperature sensors that monitor and control the internal temperature. The sensors communicate with external devices through WiFi or Bluetooth. Users can access and control the refrigerator's temperature settings remotely through an app. The smart refrigerator's display panel also allows users to monitor and control the temperature of different zones.
Door sensors
Door sensors detect whether the refrigerator door is closed or open. They ensure the proper functioning of features like door alarms and light controls. The sensors consist of a switch, a magnet, and a metal reed. When the door is closed, the magnet is near the reed, causing it to stick together and turning off the light. An open door moves the magnet away from the reed, separating them and turning on the light. The door sensor also communicates with the control board to trigger alarms if the door remains open for too long.
Ice maker sensors
Ice maker sensors control and monitor the ice-making process. They ensure the ice maker produces ice at the right time and in the right amounts. The sensors detect the water fill level, the presence of ice in the storage bin, and the temperature in the ice-making chamber. For instance, when the storage bin is full of ice, the sensor sends a signal to stop the ice-making process. It prevents the overproduction of ice. Temperature sensors in the ice maker ensure optimal conditions for ice formation.
Water filter change sensors
Water filter change sensors track the usage and age of the water filter. They monitor the water flow and the time the water dispenser or ice maker is used. After a certain period or amount of water filtered, the sensor sends a notification to the control board. Users can see the alert on the display panel or the connected app. The sensor reminds users to change the water filter to ensure clean water and optimal filtration performance.
Humidity sensors
Humidity sensors in refrigerators monitor and control the humidity levels, especially in models with humidity-controlled crispers. They help maintain the freshness of fruits and vegetables. The sensors measure the humidity level inside the crisper and send the data to the control board. Based on the readings, the board adjusts the airflow and fan operation. It ensures the crisper's humidity level remains at the desired setting. The humidity sensors also help prevent spoilage and dry out of produce.
Below are some general specifications to consider when buying an Sensor for an LG appliance:
