ML8511 UV Sensor

The ML8511 UV Sensor Module is a high-sensitivity optical sensor designed to measure ultraviolet light intensity, specifically in the UV-A (320-400nm) and UV-B (280-320nm) spectrum. It features an internal operational amplifier that converts the photodiode's photo-current into a scalable analog voltage output, making it easy to interface with microcontrollers like Arduino, ESP32, and Raspberry Pi. Key features include a wide operating voltage range (3V to 5V), low power consumption (typical 120μA), and a robust operating temperature range from -40°C to +85°C. This module is commonly used in weather stations, UV index monitors, skin exposure trackers, and smart home automation systems to detect sunlight intensity. Buyers should choose this sensor for its reliability, ease of integration with analog-to-digital converters (ADC), and its suitability for both indoor and outdoor UV intensity acquisition. It is a cost-effective solution for hobbyists and professionals seeking accurate UV detection without complex calibration.
