How does a mechanical watering clock work?

An Gardena watering clock works like this: It is attached as an intermediate piece between faucet and garden hose. With a simple knob, the irrigation time is easily set. It can be decided between minutes and hours or as a continuous rain. The water timer will start the water flow immediately and automatically close it again when the time interval has expired. A power supply is not required. A Duo Irrigation Watch Distributor works the same way, only here two strings are connected. Since each of the strands has its own time setting range, different long times can also be set here.

• Inexpensive
• Easy to handle

• no automatic start
• no timer

You will find such models in the DIY and garden markets. You can also find it sometimes Aldi watering clocks or other discounters.

How does an automatic watering clock work?

After our Irrigation control opinion  effect a simple one Watering clock Bestseller Qualities if they work automatically or with a time delay. You can preset the desired watering duration via a timer. So you can, even if you are not at home, provide your plants or the lawn with water. Watering duration and intervals are freely adjustable via a rotary control. At the selected time, the watering timer starts and switches off again after the set time has elapsed. It is just like the mechanical irrigation watch as an intermediate piece after the faucet positioned. Here, however, a power supply is needed, which is usually solved with the help of batteries.

• Inexpensive
• Easy to handle
• automatic start

• Batteries necessary
• no display

Such models are a bit harder to find at discount stores and DIY stores and garden centers are often difficult. at Amazon watering clocks order is the simpler variant.

How does an irrigation computer work?

In principle, even one works Professional watering computer just like a watering clock, except that here a programming part with display takes over the tasks of irrigation control. Depending on the model, several strands can be supplied with water at the same time, regardless of whether one should provide for a drip irrigation of vegetables and another for a sprinkling of the lawn. Start times, water inflow, cycles and duration can be individually programmed. With an irrigation computer, you can also go quite calmly on vacation. Do you have one more? Lawn Mower, not even grown your lawn, but still looks green and juicy.

Another feature that can be attached to some irrigation computer sensors. So one turns Irrigation control with rain sensor automatically when it starts to rain. An irrigation computer with a humidity sensor, on the other hand, measures the soil moisture; when saturated, it also switches off the connected irrigation system.

• Fully automatic control
• intuitively via a display
• automatic start
• often with power failure protection and battery status indicator

• Power supply necessary
• price intensive

Irrigation control with humidity sensor

A moisture sensor for measuring soil moisture is called a tensiometer. The soil moisture is measured by dehydration of the soil. The moisture meter will check if soil water is still available for your plants.

It consists of a porous ceramic cell filled with water and hermetically sealed. If the soil dries out around the ceramic cell, more and more water is removed and the resulting negative pressure triggers a pressure sensor. This allows the amount of irrigation water to be controlled so that your plants are always supplied with the optimum amount of moisture.

Hedges, shrubs or older fruit trees, do not respond so quickly to dehydration, one-year crops all the more. A monitoring of soil moisture should therefore be carried out more in vegetable beds, greenhouses or balcony plants. Especially potted plants benefit enormously from a moisture sensor.

• prevents overhydration
• automatic watering

• does not recognize rain

Irrigation control with rain sensor

We distinguish between optical, electrical or mechanical rain sensors. The sensor detects precipitation in a few seconds and gives a signal to the watering computer. It should not be in the area of ​​your sprinklers, so as not to cause false positives. Most rain sensors work a little time-delayed, because only a small amount of rain has to be collected first. So do not immediately think of a broken rain sensor, if he does not turn off at the first raindrop.

• Saves water
• automatic watering

• does not detect damp soil after the rain and starts to blast

Is there an irrigation computer app?

In the age of digitization, your irrigation computer can also be controlled via the WLAN with the corresponding app on your smartphone. An intuitive computer for garden irrigation can be controlled via:

• Bluetooth watering computer connection
• Wifi water computer connection
• App controlled irrigation computer
• WiFi watering computer control

Further energy and water saving irrigation controls are named:

• Arduino watering computer
• Easycontrol irrigation computer
• Mastercontrol irrigation computer
• Multicontrol irrigation computer

Which types of irrigation are there? 

The right water distribution determines the quality of your irrigation system. In addition to the usual water hose with spray nozzle, there are a number of sophisticated irrigation variants, adapted to any type of vegetation.

• drip irrigation
• On-line drippers
• In-line drippers
• micromister
• ground sprayer
• Düsesprüher
• Turbo sprayer
• sprinkler
• Impact sprinkler
• Flower shower
• rotors
• Mikrosprinkler

Which energy supply is the best?

If you have a socket right next to your tap, you should always use a mains supply. Electricity is a reliable institution and for a possible power failure usually provides a battery for bridging. Irrigation computers can also cope with a battery supply. This is especially useful where no mains power is available. Models with a battery level indicator are particularly useful, because the battery is discharged, no more water runs.

Which model is the right one?

Pay attention to the degree of protection your computer has and whether it can be operated outdoors or indoors or indoors.

Whether you need a mechanical or automatic watering timer or one of the best irrigation computers, you need to decide on the basis of your needs. Therefore, pay attention to our next point.

How should be poured?

Important purchase criteria are irrigation cycles, irrigation time and watering intervals.

The irrigation cycles are the times when your irrigation system should be active during the day. A watering clock should have at least two cycles to water early and in the evening.

The interval is again the time that should supply the soil with water within a cycle. It is practical if the intervals can be programmed independently, for example, earlier in the morning and longer in the evening.

The watering time is the time your irrigation computer can work at one go. That's usually two to four hours.

Is it possible to order an irrigation computer on the internet?

We can answer this question unambiguously with yes, because here is the whole range of models available on the market. Here you not only have a good comparability of the individual models, but can at hand a Irrigation computer Price comparison estimate the pros and cons of the price / performance ratio. Often here are too Water computer reduced to find or some other bargains. The nicest thing about Amazon irrigation controllers is that you can still find a lot of customers Irrigation computer opinions scour. That's what everyone should do Irrigation computer Bestseller .

Who makes the cheapest irrigation computers?

Good and cheap is always a double-edged sword. Although the market leaders always have a slightly higher price, they can not afford quality defects. This does not mean that no-name products are not equivalent, but you make the decision depending on the desired model or budget. Here are the main manufacturers at a glance:

Gardena | Kärcher | Aqua Control | Orbit | Panthonor
