radcal_212_1105
RAD for the R/V Bigelow. Abscissa is the sensor output and ordinate is the irriaiance in W/m^2. Note the range of PIR output (bottom left) is on the order of 10 microvolts.
RAD circuit board.
The microcontroller is based on the AVR microchip, a very popular and versatile microcomputer. The above circuit board features preamplifies, 12-bit ADC, two com ports, digital control lines and power regulation. The AVR programs in floating-point C. It operates on flea power and has watchdog timers and a real-time clock.
