Leaf Wetness Sensor – HD3901

Accurate Leaf Moisture Detection for Agriculture, Disease Prevention & Weather Monitoring

The HD3901 Leaf Wetness Sensor is a precision environmental sensor designed to detect the presence and duration of moisture on leaf surfaces, helping monitor conditions that influence plant diseases, fungal infections, irrigation timing, and crop health management. It is widely used in agriculture, vineyards, orchards, greenhouses, and meteorological stations where leaf wetness data is critical for disease forecasting and smart irrigation decisions. The sensor simulates the thermal and moisture behavior of a real leaf surface, providing highly reliable wet/dry detection under natural environmental conditions. Its rugged outdoor design ensures dependable long-term field performance even in harsh weather conditions, making it ideal for permanent installation in professional agricultural and environmental monitoring systems. The HD3901 integrates easily with weather stations, data loggers, and irrigation automation systems for continuous monitoring and better crop protection.
