The light sensor features an advanced digital ambient light sensor, known for its exceptional sensitivity in light collection. It offers high sensitivity and fast response times, closely matching the human eye's spectral characteristics. Its peak sensitivity occurs at a wavelength of 560nm, with minimal interference from infrared light. Combined with high-precision analog circuits and software processing, it ensures accurate correction of the light curve, enabling highly precise light value output.
To ensure stable measurements, the sensor includes a 50Hz/60Hz frequency debounce function. It filters visible light that reaches the photodiode, which then converts the visible light into electrical signals. These signals are processed by the microcontroller system, which also compensates for temperature effects using a built-in temperature sensing circuit. The product supports the Modbus-RTU protocol and offers multiple analog transmission options for user flexibility.
