Irrigation Controller

Here a Compact Version of the Irrigation-Controller

A lot of precious water is wasted due to unprofessional irrigation worldwide. This Device is reducing the water demand by exactly detection the water demand and Time. And you can have a kind of Trickle-Irrigation-System without having the high cost for it. There are two Units available for this. Look down for the compact Versio

Following features are integrated in the Irrigation-Controller called “Metamorphosis”:

 Programmable Irrigation-Times for ten independent Channels; The Irrigation-Time ranges from one second up to days (every second day for example)

Additionally you can have up to four different on/off-times programmed one day for one channel

The irrigation-program can be controlled by up to four simple (self-made) Irrigation-Sensor . Each sensor belongs to one channel or you can have a average-calculation of the Sensors. Of course you can connect any other Humid-Sensor, which is available at the market. You give a Set-Point for humidity and when the ground-humid is less than the Set-Point the irrigation time-program is enabled; You can connect only one or up to four irrigation-Sensors.

Automatic Irrigation-Time calculation, to have optimized Irrigation depending from the Humidity of the ground.

Automatic Detection for the best Start-Time for Irrigation (at night). You only have to program how long the Irrigation should last

There is a integrated anti-corrosion protection for the sensors and a temperature-compensation for a more accurate measuring.

You can use Pulsed Valves, that means they only need a Pulse for to switch on and off.

Anti-Blocking-System for to prevent blocking of the Pump if it was not activated for longer. That means the Output will be switched on daily for some seconds, if there was no automatic Start.

In order to get widespread roots on the plant you can have a programmed suppress of irrigation every month for 2, 3, 4 or more days.

You can connect 12V, 24V, 220V-Pumps and even 380V three-phase Pumps with up to 3000 Watt!

The device can be shipped with a high grade Solar Charge-Controller for a Solar-Water Pump . You can connect solar-panels (up to 35A!) and batteries. (See more details on the Solar Charger in the according chapter). You have up to five Load-Output channels. Each can be programmed individually by Voltage, Time and optional additional Sensor-Inputs. All essential Parameters can be programmed.

Irrigation-System and Solar-Panels are outside and often there are Problems with thieves. With the Metamorphosis you can build up a sophisticated Alarm-System:

there is an alarm if the door of the switch box is opened
With a Moving-detector: Alarm if somebody is coming near the System
With a external Circuit: A high voltage is activated at the Panels-Frame or Pump, as soon as somebody is coming to the System. Of course the voltage can not hurt anybody
Up to three additional Alarm-Inputs can be programmed
The Alarm can generate a Telephone-notification or SMS and a loud Alarm-Horn can be connected

In order to get information about the quality of  the water you can connect a conductivity-sensor and the relatively conductivity of the water will be displayed which is a good parameter for the quantity of minerals in the water

If you are not using all four humid-sensors (in most cases one sensor is enough) you can connect temperature-sensors as well and the value will be displayed.

With the temperature-sensors you can check the water-temperature (best is 25 degrees;  min. is 15 degrees, max is 35 degrees) for example

On the other side the temperature-sensors could be used for heating or cooling (a glass-house) as well. With the temperature-sensors you can have up to four temperature (and time) controlled outputs.

With the system you can also program a frost-protection irrigation. If the temperature is below a Set-point, a frost-protection irrigation starts. Temperature-Controlled-irrigation is also a good way to smoothen the extreme temperatures. This can be easily realized by the Metamorphosis.

You can connect a level-sensor (available from Alternative Technology) in the water-vessel for that the pumps do not run without water. It doesn’t matter whether the switch opens or closes if it is empty.

bistable Relay can be used (they need Power only for to switch over)  

even if you don’t have a level-switch there is a integrated automatic supervision of the water-flow

Automatic fill up of the storage-tank with a additional pump (with the internal relays max. 16A) using the level-sensor. You can input a fill-up-time for the pump (1-255min).  After this time the pump is switched off or you have a second full-sensor. 

Integrated Pasteurization-Function for to clean water from bacteria and microbes in order to get potable water. Potable water is a serious problem in many countries! The System works by measuring the Temperature and Time and when satisfies the requirement a Pump is switched on to get the next Batch of water.

There is of course a Manual-mode for all connected devices likes Pumps, Fan etc. And you can switch the devices also from remote using a modem / Mobile-Phone connection (For example Siemens S35).

Up to 4000 measured values (humidity, temperature, ...) will be stored in the Metamorphosis. In case of power-failure the data will not get lost! This Data can be uploaded at any time by a PC/Laptop with a cable, a modem or by a GSM Mobile-phone.

You can fully remote control the System by a PC/Laptop via a Modem/ Mobile-phone. Change all parameters, switch on and off the Pumps and supervise the measured values. You get a additional Software on CD running on Windows 95/98/ME/2000/XP to upload the data in a file and to remote-control the Metamorphosis.

Additionally you can switch on and off the Pumps by sending a SMS to the Metamorphosis

It is no problem to connect lamps or any other device (up to max. 10 A each channel) to the Metamorphosis and program on / off times for them (glass-house illumination)

You do not need external Power-Switches. You can connect four 12V or 110V/220V Pumps or Motors with max. 3000 Watt (1000 Watt per channel). On the other side all 12V, 24V, AC or DC-Valves can be connected.

Rainwater-cisterns are a good and interesting System. With this device the emergency water feeding of the cistern in case of a empty Cistern can be realized and the running-dry protection for the pumps.

The specific name of inputs and outputs can be written to a text file, and loaded into the metamorphosis. This information is displayed on the display at the Universal channels and messages.

Specific Alarm-Messages can be defined in a text file and loaded into the device for display.

The time for Irrigation can be adjusted automatic in relation to the ambient temperature

There is a Legionella-Alarm when the temperature is below 50 ° C

A main aspect of the Device is a very simple Programming of all the features. For example to have several start-programs a day you simply program ”irrigate all 2 hours, starting from 20 o’clock till 6 o’clock”, that’s it!

Anyway, these are some options you have with the device. But you can have your own features. Say what you want and we program it. For example why not combining a irrigation-System with a Alarm-System. Solar-Panels are not cheap and get stolen frequently. It is a open System and you can download new versions via the Internet. You get all necessary cable for to download it to the Metamorphosis

Make your own Programs! You can use it also for your own Applications as a Micro-Controller-Development-System. The Basic-Compiler is free for small Programs. There is an Open-Source Software and Template for that for free. Look at System/Mikrocontroller System.html

The above mentioned features are the Maximal Configuration. If you order please ask for the features you really need
