ALS-PT19 Analog Light Sensor Module

The ALS-PT19 Analog Light Sensor Module is a highly efficient, integrated solution for detecting ambient light in electronic projects. It offers a broad detection range and closely aligns with the spectral response of the human eye. With its simple analog voltage output, it is ideal for beginners and projects requiring straightforward light sensing without the complexities of digital interfaces.

Features:

• Broad Detection Range: Detects light in the UV spectrum of 240–370 nanometers (UVB and most UVA).
• Precise UV Sensor: True UV sensor (uncalibrated visible light). Divide output voltage by 0.1 volts to obtain UV index.
• Signal Amplification: Amplifies low nanoampere signals to readable voltage using an operational amplifier.
• Low Power Consumption: Operates on a DC voltage ranging between 2.5 volts and 5.5 volts. Voltage increases with light intensity.
• Easy to Use: Outputs analog voltage. No need for I2C configuration.

This sensor is perfect for developing photovoltaic cell-based light detection projects. It is easier to use than digital alternatives like Si1145, making it suitable for basic or analog applications. Thanks to its strong ability to reject infrared radiation, this sensor mimics the sensitivity of the human eye to visible light.
