Functions: soil moisture detection, soil pH detection, soil light detection Applicable: suitable for greenhouse planting, farmland planting, potted planting, gardening planting, and tree planting Benefits and features: - Provides quick, combined readings for moisture, pH, and light to guide irrigation, soil management, and plant care - Helps reduce guesswork and support healthier plants by delivering actionable data in one device - Compact probe design with an electrode head for reliable readings across common soils - Simple three-parameter measurement in a single instrument Important usage notes: - If the soil is too dry, moisten the soil first - Do not force insertion; hard insertion can damage the electrode head - Protect the electrode head during use to avoid instrument damage, which can reduce service life and detection accuracy Use scenarios: - Greenhouse planting: monitor moisture, pH, and soil light to optimize vegetables and herbs - Farmland planting: field checks across plots to guide irrigation and lime/fertilizer decisions - Potted plants and garden beds: routine readings for houseplants, herbs, and landscape beds to maintain balanced moisture, pH, and light exposure
