Description
Soil moisture sensors, sometimes referred to as soil humidity sensors, measure the amount of water in soil and are useful for watering plants only when required and to avoid over-watering or under-watering. There are three main types of soil moisture sensors:
- Resistive
- Capacitive
- Temperature & Humidity
Resistive soil moisture sensors have two exposed conductive probes that act as a variable resistor, with a resistance that varies inversely with the amount moisture content of the soil (more water in the soil lowers the resistance). The sensor outputs an analog voltage according to the amount of resistance.
Capacitive soil moisture sensors work by measuring small changes in capacitance caused by changes in the dielectric that is formed by the soil and water. Capacitive soil moisture sensors do not require direct exposure of the metal electrodes and are also made of a corrosion resistant material. This significantly reduces corrosion and gives them a longer lifespan compared to resistive soil moisture sensors.
Temperature and Humidity soil moisture sensor probes have a metal sintered mesh housing that keeps dirt and water from seeping into the sensors, but allows air moisture to pass through so it can measure the humidity of the soil. These sensors are more accurate and reliable than resistive and capacitive soil moisture sensors because they don't depend on soil composition and density, but they are more expensive.
