Electric leaves just like the Mist-A-Matic have a supply that pivots. On one conclusion is really a screen that stays up in the air that water gathers on through the misting cycle. When enough water has collected on this screen, the supply pivots downward. One other conclusion of the supply then comes in contact with a small change which will interrupt the electric signal to the solenoid.


When water evaporates down the leaf, it again raises and enables the electrical signal to work the solenoid. The theory behind the electric leaf is for this to imitate a real leaf and the charge of evaporation. While several propagators have had great success with digital leaves, others have come across disasters. Something as easy as a pest or chicken losing will keep the leaf in the downhill position, stopping ALL water from addressing the cuttings.


Unless this really is instantly recognized, the cuttings will truly die. Water devices and freeze sensors can also be wired in to a impianti antizanzare system to interrupt the flow of moisture to the cuttings. The idea behind a rain sensor is to stop the solenoid device from starting throughout wet weather. Unless your cuttings are being grounded in a greenhouse or hoophouse (more on why you don't require one particular later...)


Your misting system does not require to perform within a rain event. The rain is keeping the cuttings humid and there is you should not spend water. The rain warning has a small glass with a plunger inside. When this plunger gets moist it gets pressed downhill and connections a move that stops the electrical signal to the solenoid valve. Once the rain prevents and the plunger rises, energy can now arrive at the solenoid.


One problem to the rain warning is in case a chicken dropping gets to the cup and maintains the plunger down, however the cup is so small the likelihood of that is slim. Freeze devices function in an identical fashion except they remove the power to the misting solenoid once the temperature comes to about 37° F. When the warning detects the temperature at or below the prospective, it interrupts the signal to the solenoid.
