The UVA sensor is an ultraviolet light sensor, which primarily responds to UVA radiation (approx. 220 to 390 nm). The UVA sensor is built around a UV sensitive Schottky photodiode. The diode produces a current proportional to the UV intensity. The signal from the diode is amplified through a transimpedance amplifier and sent to the output.
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
