What is Moisture Sensor and applications?

Soil moisture sensors measure the water content in soil. Since the direct gravimeter measurement of free soil moisture requires removing, drying, and weighting of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant, or interaction with neutrons, as a proxy for the moisture content. The relation between the measured property and soil moisture must be calibrated and may vary depending on environmental factors such as soil type, temperature, or electric conductivity. Reflected microwave radiation is affected by the soil moisture and is used for remote sensing in hydrology and agriculture. Portable probe instruments can be used by farmers or gardeners.
Soil moisture sensors refer to sensors that estimate water content. Another class of sensors measure another property of moisture in soils called water potential; these sensors are usually referred to as soil water potential sensors and include tensiometers and gypsum blocks.

  1. Over the past years, environmental monitoring has become important. The moisture plays an essential role in the irrigation field as well as in gardens for plants. The moisture sensor is one kind of sensor that used to measure the water level in the air and soil etc. Ubibot wifi humidity sensor help to detect the level of moisture. Moisture sensors used in many industries such as Agriculture, Archeology, Weather Station Networks and in House.

  4. Great job for publishing such a nice article about moisture absorber. CILICANT moisture absorber pouch removes water or moisture from the air in container. Moisture absorber pouches hold both a Type III DMF (Drug Master File) and a Health Canada Master File (MF). and available in Pre-cut silica gel, activated carbon strips, and molecular sieve and custom blend bags. thanks for sharing
