Digital soil moisture display and auto watering controller Digital display shows current soil moisture level for easy monitoring. Automatic irrigation when needed: when the soil moisture is below the set value, the pump is activated to water; it stops when the moisture reaches the set value. Direct soil insertion: the moisture probe can be inserted directly into the soil for accurate readings. Set value threshold: the moisture level at which watering starts and stops is defined by a set value to suit different plants and soils. Practical benefits: helps prevent overwatering and underwatering, reduces manual monitoring, and supports consistent plant health. Use scenarios: 1) Indoor potted plants and houseplants to maintain steady soil moisture with minimal effort. 2) Small balcony container gardens to manage moisture across several pots with one controller. 3) Greenhouse seed trays or beds to maintain precise moisture during germination and growth.
