A soil moisture meter is a device used to measure the water content in soil. It provides real-time moisture readings to help gardeners, farmers, and landscapers monitor and manage soil conditions effectively. By inserting its probe into the soil, the meter detects the amount of moisture present and displays it on a scale, which can be analog and digital.

These meters are especially useful for optimizing plant health, as they ensure plants receive the right amount of water without overwatering or underwatering. Soil moisture meters come in various types, including basic models for indoor plants, and more advanced ones for agriculture and environmental studies.
