Solar insolation sensor, interface, and mounting hardware. IntroductionThis is an affordable, high quality, solar insolation sensor. The sensor is a Davis Weather 6450 solar radiation sensor with permanently attached interface electronics. The calibrated solar radiation sensor can measure 50 w/m^2 to 1800 w/m^2. The sensor comes standard with a 3 meter (10 foot) CAT5e cable integrated. Longer CAT5e or unterminated shielded cable is available as a special order. Photos of the sensor in action can be found in the photo gallery. Specifications
One of our customers leveling the solar insolation sensor. Wind Data Logger ConfigurationThe solar radiation sensor is plugged into the "TEMP&ADC" connector on the Wind Data Logger using a straight through cable / patch cord. If you wish to use the included temperature sensor you should use an 8Y splitter. To display actual sensor readings on the Wind Data Logger you will need to configure the ADC channels. The following equations are used to convert the voltage output from the sensors to standard units: Light Intensity:watts / meter^2=598.802*Vin (ADC M: 598.802 / ADC B: +0.0 / ADC Units: W)The values in parenthesis should be entered into the ADC setup screens on the Wind Data Logger. Example DataThe following data was capture on 2006-11-09 near Winona, Minnesota, USA.Solar Insolation
Raw DataThe raw data used to generate these plots is available as example_wiscoy.csv. Note that this data has been exported from our SQL database and is in a slightly different format than what is stored by the Wind Data Logger. |
