Moisture & Nutrient Sensor
The SoilQuality sensor is a remote sensor which connects to your phone or smart device by Bluetooth and provides real-time data of your growing media (coco, rockwool & soil)
EC Measurement
Soil Quality measures the Electrical Conductivity (EC) of soil and growing media.
At a given temperature, the EC of any growing media is relative to the amount of nutrients - an increase in nutrient produces an increase in Soil Electrical Conductivity. Temperature is a factor that which affects the EC level. The higher the temperature the higher the EC. Most EC agricultural standards are given at 25°C. As a rule of thumb, the EC of water increases by 2 to 3% for each increase of 1°C.
To capture nutrients in the growing media, a plant needs water so minerals can be dissolved in water and be available as nutrients to the plant. In a dry growing medium a plant will not be able to grow and capture any nutrients. EC is also affected by the soil moisture: when the soil is dry, the EC greatly drops even if there are minerals available.
Comparison of Nutrient level in time or between different samples should be done based on the same moisture level and temperature.
Measuring Moisture
The 'SoilQuality' moisture measurement is given in Absolute Volume Ratio (AVR), which is the ratio between the volume of water divided by total volume of Soil + Water after mixing both.
At 70% AVR moisture the soil becomes extremely close to a liquid and not adequate for growing. SoilQuality provides a AVR Soil Moisture measurement between 0 to 70% (anything above 70% will still show as 70%).
EC Measurement in nutrient solution
Although SoilQuality has been designed to measure EC of moist soil, it can also measure the hydroponics nutrient solutions, however the following precautions should be followed:
