Tips: How to properly use the soil pH sensor?

1. The soil pH sensor’s steel probe must be fully inserted into the soil during measurement.
2. Avoid direct sunlight on the sensor to prevent overheating. Take precautions against lightning when used outdoors.
3. Do not bend the steel probe forcefully, pull the sensor cable, or drop/strike the soil sensor.
4. With an IP68 protection rating, the sensor can be fully submerged in water.
5. Due to the presence of RF electromagnetic radiation in the air, the soil pH sensor should not remain powered on for extended periods outside the soil.
