Follow these steps to take accurate soil measurements:
- Ensure the meter is powered on and connected to your smartphone via Bluetooth.
- Gently insert the metal probe 2-4 inches (approximately 5-10 cm) into the soil you wish to test. Ensure the probe is fully submerged in the soil for accurate readings.
- Wait for a few moments for the readings to stabilize on your smartphone app.
- Avoid forcing the probe into hard soil to prevent damage. If the soil is too hard, moisten it slightly before insertion.

5.2 Oye kika
The app displays various parameters. Here's a brief overview:
- pH: Measures soil acidity or alkalinity (0.0-14.0 pH).
- EC (Ìgbékalẹ̀ Ìmọ́lẹ̀ Iná): Indicates the concentration of soluble salts in the soil (0.01-9.99 mS/cm).
- Iyọ: Direct measurement of salt content (0-5110 mg/L).
- Irọyin: Assesses the overall nutrient level in the soil (0-99%).
- Ọrinrin ile: Indicates the water content in the soil (Dry, Normal, Wet).
- Ọriniinitutu afẹfẹ: Measures the humidity of the air surrounding the plant (0-100% RH).
- Iwọn otutu: Measures both soil and ambient temperature (0.0-50.0°C / 32.0-122.0°F).
- Ikun Imọlẹ: Detects the light level (Dark, Normal, Bright).
