iBebot SoilQuality Sensor

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). This is a revolutionary product for soil growers and will make your life very easy when paired with the iBebot Hub switch.

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.

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 note the following precautions:

  • Protective cap should be removed!
  • During measurement, the moisture level will be saturated at 70% - this is normal.
  • The 'Soil Sensing Probe' should be fully immersed into the solution - half immersed Sensor Probe will result in a half reading.
  • The measured EC value should be compared with a reference EC value of a buffer solution given at the same temperature as the sampled liquid. Unlike some other sensors, this unit does not have ATC ( automatic temperature compensation).
  • The 'Soil Sensing Probe' should be gently cleaned with disinfectant alcohol if EC reading doesn't match with expected value

To capture nutrients (EC) 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’s minerals available.

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%).

'Soil Sensing Probe' should be gently cleaned with disinfectant alcohol if moisture reading doesn't reach 70% in water.

Comparison of Nutrient level in time or between different samples should be done based on the same moisture level and temperature.
































Level Up
































Plug in the iBebot Hub switch nearby so it can communicate with the Soil Quality Sensor, and when moisture reaches the level set you can switch on the plug from your smart phone. If the irrigation pump is plugged in, this will enable you to water your garden at the optimum time!
