The RG-10 may also provide drop detection. Use this mode if you want to do your own external data interpretation. The output will pulse once with each detected drop. Normally, it will produce longer pulses (in multiples of 200 mS) for larger drops. If set to multiple pulses per drop (SW 3 ON), each detected drop will generate one or more 100 mS pulses, depending on drop size.
Rain Tracker Rain Gage - Model RG-10
# Maintenance free
# Compact-- about the size of a tennis ball
# DIP switch programs the function and outputs
# Extremely sensitive. The sophisticated circuitry and DSP algorithms count and totalize individual raindrops. If you need something to detect the first raindrop, this can be your solution.
# Internal heater for cold weather applications
# 9 - 35VDC Operation
# Two Open collector outputs
# No mechanical parts. It is not affected by jostling and motion. Can be completely mobile, and mounted in any orientation
# Round sensing surface is essentially self-cleaning
# No exposed conductors to corrode. No openings for bugs to crawl into or for spiders to build nests. The Rain Gage compensates for surface grime or other degradation, so in most cases no maintenance is needed
# Daylight and temperature sensing
# Optical rain sensor can also detect other liquid
Weather-Above will be experimenting with this amazing new device soon
I have tested the rain sensor , I connected a relay which is operated by the rain sensor output As soon as the rain sensor receives 0.0001" on the surface of the lens the relay is activated. The relay is connected to a Hobby board counter, this enables the information to be interfaced to a 1 wire weather station,
