The
Mini Click II is the best selling rain sensor in the world. It measures rainfall
through moisture absorbing (hygroscopic) disks. There is no collection cup to
clog up so it requires no regular maintenance.
You can set the sensitivity to allow 1/8, 1/4, 1/2, 3/4 or one inch (25mm) of
rain to fall before it switches the system off.
The housing is made of UV resistant thermoplastic, and the mounting bracket is
aluminium, so this unit is built to last.
Unlike sensors that are buried in the ground to measure soil moisture the Mini
Click II will not get in your way, it is mounted safely above ground, often on
the side of a building.
