A Leaf Wetness Sensor is a device used to measure the moisture level on plant leaves, providing valuable data for agricultural practices, environmental monitoring, and research. It enables more precise irrigation, leading to water conservation and healthier crops. They provide early warning of conditions that may lead to disease outbreaks, allowing for timely interventions. The sensor helps farmers monitor leaf moisture to optimize irrigation schedules and reduce water waste. This aids in greenhouse and landscape management by providing data on plant health and water needs. Leaf Wetness Sensor is designed to withstand outdoor conditions, including exposure to rain, UV light, and temperature variations.
