The UV Light Sensor measures ambient ultraviolet intensity in the 200 to 370 nanometer range, within the solar ultraviolet UVA, UVB, and UVC light spectrum. The sensor has a built-in amplifier with adjustable levels. The UV Light Sensor may be used outdoors in a variety of applications including datalogging and closed-loop control, such as for activating watering or greenhouse vents.
The single analog output may be directly connected to the Propeller Activity Board 4-channel A/D converter or easily interfaced with the MCP3002 A/D with a FLiP Multicore Microcontroller.
UV Light Sensor Features:
- Partial UVA (370-340nm), UVB (340-315 nm), partial UVC (315-200 nm) light measurement with a simple analog output
- 200–370 nm response spectrum for a wide range of natural solar light levels
- Adjustable amplification
- 2 to 5 volt analog output is easy to read by many controllers or A/D converters
- 9 inch (22 cm) 3-pin female-female extension cable included
