Getting started

Battery installation

• Remove battery cover
• Place 1x AAA battery into SoilQuality
• Replace cover to matching position marks between main body and cap After changing the battery, you must synchronise SoilQuality with our mobile APP, performing this updates SoilQuality’s internal date & time registry and allows log recording.

Inserting the sensor on soil

• Remove protective cap
• Gently clean with disinfectant alcohol front and back of the ‘Soil Sensing Probe’
• Insert SoilQuality’s into soil until the ‘Soil Sensing Probe’ is completely buried inside soil

Connect to Phone

SoilQuality operate with our mobile application AirComfort. The mobile application is free and available on both Android and iOS.

• App installation, use this QR code or browse to www.tektosdesign.com/air-comfort-app.php
• Turn on ‘wireless communication’ in your phone
• Enable ‘Location’ permission in your phone
• Launch Application
• Tap Menu
• Tap ‘Add / Remove Sensors’
• Select your SoilQuality, TAP it (right circle will show as “green”)
• Tap ‘✓’ icon to start using SoilQuality
• Once download is complete, SoilQuality will be visible on the ‘Sensor’ Home page.

iBebot Connect

“iBebot Connect” is a Web platform available on www.ibebot.com that provides a desktop interface with complementary features to the mobile application for SoilQuality and AirComfort. The platform offers:

1. Chart, to plot all sensors with unlimited history and data record backup.
2. VPD (Vapour-Pressure Deficit) computation and graphing
3. Mold risk probability
4. Grow room Mapping
5. Export to CSV (excel)
6. THI (Temperature Heat Index) computation and graphing
   *Current print run items 2 – 6 require a paid subscription

Soil Moisture measurement

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 plant growing in soil. Therefore, SoilQuality has been designed with full scale at 70% and provides AVR Soil Moisture measurement between 0 to 70%; above 70%, the reading with remain at 70%.
‘Soil Sensing Probe’ should be gently cleaned with disinfectant alcohol if moisture reading doesn’t reach 70% in water.

EC Measurement and Soil Nutrients

1. SoilQuality measures the Electrical Conductivity (EC) of soil.
2. On moist soil, at a given temperature, the EC of soil is relative to the amount of nutrients in the soil: an increase of the nutrient produces an increase in Soil Electrical Conductivity.
3. To capture nutrients in the soil, a plant needs water so minerals can be dissolved in water and be available as nutrients to the plant. In dry soil a plant will not be able to grow and capture any nutrients. Soil EC is also affected by the soil moisture: when the soil is dry, the EC greatly drops even if there’s minerals in the soil. Therefore, the Soil EC gives a good relative indication of the available nutrients to the plant.
4. Temperature is also a factor that will affect the soil’s EC level. Most EC agricultural standards are given at 25°C. The higher the temperature the higher the EC. As a rule of thumb, the EC of water increases by 2 to 3% for each increase of 1°C.
5. Comparison of Nutrient level in time or between different soil samples should be done based on the same moisture level and temperature.
6. When mixing a soil with a water solution, it is important to note that the resulted EC of the soil will be according on the EC level of the water solution combined with the mineral level of the soil and the moisture level of the mix of both.
7. Although SoilQuality has not been designed to measure EC level of water or buffer solution, it is possible to measure the EC in those liquid, however:
8. Protective cap should be removed.
9. During measurement, the moisture level will be saturated at 70%, this is normal, please see Part 9 for more information
10. The ‘Soil Sensing Probe’ should be fully immerged; half immerged ‘Soil Sensing Probe’ will result in a half reading
11. Measured EC value should be compared with reference EC value of the water solution or buffer solution given as the current temperature of the liquid measured
12. The ‘Soil Sensing Probe’ should be gently cleaned with disinfectant alcohol if EC reading doesn’t match with expected value
