Capacitive soil moisture sensors: These sensors measure the electrical capacitance of the soil to determine its moisture content.
Tensiometers: These devices measure the tension or the negative pressure in the soil, which indicates the amount of water that the plant roots can extract.
Time-domain reflectometry (TDR) sensors: These sensors use electromagnetic pulses to measure the soil's moisture content. The time taken by the pulses to travel through the soil is used to calculate the soil's water content.
Neutron probe soil moisture sensors: These sensors measure the soil's water content by detecting the amount of hydrogen atoms in the soil. Water contains hydrogen atoms, so the measurement of hydrogen atoms can be used to determine the soil's water content.
Resistance-based soil moisture sensors: These sensors measure the soil's resistance to electrical current flow, which is influenced by the moisture content of the soil.
Dielectric permittivity sensors: These sensors measure the dielectric properties of the soil, which are related to its water content.
Infrared thermometers: These sensors measure the surface temperature of leaves to determine the plant's water status. When the plant is short of water, the leaves become warmer.
Psychrometers: These devices measure air humidity and temperature to determine the plant's water status.
Leaf wetness sensors: These sensors detect the presence of water on the leaves of the plant, which can cause diseases.
Acoustic sensors: These sensors detect the soundwaves generated by the flow of water in the plant tissues to determine the water status of the plant.
Solar radiation sensors: These sensors measure the amount of solar energy that reaches the plant, which is used to determine its water needs.
Soil temperature sensors: These sensors measure the soil temperature, which is an important factor that affects plant growth and water uptake.
GPS and GIS-enabled sensors: These sensors use geographic information systems (GIS) and GPS technology to determine the soil's moisture content based on its location and environmental factors.
