Solinst Rainlogger 5 WQ101 we offer less-common sensors includingThe Solinst Rainlogger 5 is an event based datalogger, not a pressure sensor it connects to a standard tipping bucket rain gauge with a reed switch output and records a timestamp each time the bucket tips, rather than sampling at fixed intervals. Housed in ABS plastic on the same electronics platform as the Levelogger 5 family, it stores up to 100,000 time stamped readings and communicates optically via USB, the same way other Solinst dataloggers do.
