Integration of Sentry™ Visibility Sensor into Campbell Scientific Data Logger CR1000

Abstract

In this paper, how to integrate Sentry™ Visibility sensor with Campbell Scientific CR1000 series data loggers is described. The CR1000 is the product of Campbell Scientific, which provides precision measurement capabilities in a rugged, battery-operated package. It consists of a measurement and control module and a wiring panel. Standard operating range is -25°C to+50°C and it is widely used to get data. SVS1 Sentry™ Visibility Sensor measures atmospheric visibility (meteorological optical range) by determining the amount of light scattered by particles (smoke, dust, haze, fog, rain, and snow) in the air that pass through the optical sample volume. The detailed integration steps between the data logger CR1000 and SVS1 Sentry™ Visibility Sensor is given. The steps include: 1) establish communication with SVS1 Sentry Visibility sensor via RS-232 port of PC: 2) write down the instrument communication parameter settings. 3) make necessary electrical and data line connections to data logger. 4) program the data logger to acquire data from Sentry™ Visibility Sensor. Practice proves that the acquisition method is feasible.
