UV-A sensor

The UVA sensor is an ultraviolet light sensor, which primarily responds to UVA radiation (approx. 320 to 390 nm). The UVA sensor is built around a broadband UV sensitive silicon photodiode. The diode produces a current proportional to the UV intensity. A wavelength selective filter limits light striking the diode to only the UVA region. The sensor includes a built-in light diffuser to make the readings somewhat less sensitive to the orientation of the sensor.

Examples of experiments
• Measure the UV intensity as a function of time throughout the day.
• Measure the UV transmittance of various sunglasses and regular glasses.
• Measure the UV transmittance of fabrics, both wet and dry.

The UVA sensor can be directly connected to analog BT inputs of the CMA interfaces.

Technical specifications of the sensor are described in its User's guide.
