A moisture sensor is a device that measures the amount of moisture in a substance or environment. It is commonly used in agriculture to monitor soil moisture levels for optimal plant growth, and in household appliances like humidity sensors in air conditioners and clothes dryers.

Hygrometers work by using a sensor that responds to changes in humidity levels. This sensor typically contains a material that absorbs or releases moisture based on the surrounding humidity. The hygrometer then measures the changes in the sensor's properties, such as electrical resistance or capacitance, to determine the humidity level accurately.
A clothes dryer moisture sensor works by detecting the humidity level inside the dryer. It uses electrical conductivity to measure the amount of moisture in the clothes as they tumble. Once the desired level of dryness is reached, the sensor signals the dryer to stop drying to prevent over-drying.
The sensor pad on the BlackBerry 8520 may not be working due to dirt or moisture accumulation, physical damage, or software issues. Try cleaning the sensor pad with a soft cloth, restarting the device, or updating the software to see if it resolves the issue. If the problem persists, it may require professional repair or replacement.
You can use silica gel packets or moisture-absorbing crystals to safely absorb moisture.
To determine the moisture content of soil, you can use a soil moisture meter or follow the oven-drying method. With a soil moisture meter, insert the probe into the soil and read the moisture level displayed. For the oven-drying method, weigh a soil sample, dry it in an oven, and weigh it again to calculate the moisture content.
