The Data Logging Rain Gauge consists of two major components: a Tipping-bucket Rainfall Collector, and a HOBO® Event/Temperature Data Logger.
The collector consists of a black powder-coated aluminum knife-edged ring, screen, and funnel assembly that diverts rainwater to a tipping-bucket mechanism located in an aluminum housing. The housing is white powder-coated aluminum designed to withstand years of exposure to the environment. The tipping-bucket mechanism is designed such that one tip of the bucket occurs for each 0.01″ (RG3) or 0.2 mm (RG3-M) of rainfall. Each bucket tip is detected when a magnet attached to the tipping-bucket actuates a magnetic switch as the bucket tips, thus effecting a momentary switch closure for each tip. The spent rainwater then drains out of the bottom of the housing. The switch is connected to a HOBO Event/Temperature data logger, which records the time of each tip.
The data logger is a rugged, weatherproof event logger with a 10-bit temperature sensor. It can record 16,000 or more measurements and tips. It uses a coupler and optical base station with USB interface for launching and data readout by a computer. Data shuttle options are also available.
