1. Most potted plant deaths are caused by water shortage or overwatering. This soil moisture sensor emits a sound when the soil is dry, reminding you to water your plants. This helps prevent overwatering due to concerns about underwatering. 2. There is no need to monitor numerical readings; simply water your plants when the device activates. This makes plant care easier and more intuitive. 3. The cute design doubles as a decorative piece for flowerpots, enhancing the appearance of your garden or indoor space. 4. The device is easy to use. Remove the insulating sheet from the bottom to activate. Insert the probe into the soil. It may initially emit bird or frog sounds, but will stop once moisture is detected. 5. A standard button battery provides up to one year of operation. A built-in light sensor automatically disables the sound function at night to avoid disturbance. The device resumes operation during daylight hours. To activate, remove the insulating film from the battery compartment. To disable the sound, press both probes simultaneously or insert them into wet soil. After inserting the probe, the sound should stop shortly. If the sound continues, it indicates the soil is dry and watering is needed. The optical sensor ensures the reminder is silent at night but may briefly activate in daylight to indicate power status. Watering: When the device activates, check soil moisture and water if necessary. Color: Yellow/Black Material: Resin Size: 18 x 9 cm Package Contents: 1 x Soil Moisture Meter Note: Clean the probe tip periodically with fine abrasive paper or steel wool for optimal performance. The device detects soil moisture levels. If the device continues to activate after watering, check soil conditions. Ideal soil pH for most indoor plants ranges between 3 and 8.
