# Greenhouse
Automation and monitoring of greenhouse
> **⚠ NOTE**
> Especially in product descriptions of this project it may happen that the language German is used. This project is still in the development phase, so far only the irrigation, light and ventilation have been realized. Further sensor technology such as temperature, humidity, brightness are in planning and will therefore be added successively.
## Vitavia Greenhouse "Apollo 5000" anthracite, 4 mm HKP
The baseline for this project is the Apollo 5000 from Vitavia in color anthracite. The supplied galvanized steel foundation protects the greenhouse against wind influences, we have made 6 point foundations á 70cm (arm length) concreted for this. The construction is not quite easy with the included instructions, is supplemented here by numerous private construction videos on YouTube.
## Ventilation
We deliberately chose a mechanical variant for ventilation:
__Thermovent® Ventomax® Sesam Spiro® - Orbesen Teknik Denmark__
The Ventomax® vent opener is a well-proven standard hydraulic cylinder. The Thermovent® give you a very cost effective vent opener with a brilliant corrosion protection. The Sesam Spiro® keeps the hydraulic cylinder inside the greenhouse no matter if the window is open or closed.

## GARDENA MIKRODRIP SYSTEM
The __GARDENA Basic Unit 1000__ reliably reduces water pressure to __about 1.5 bar__ for optimal operation of drippers and nozzles.

## PURCHASE LIST
We get a discount at OBI, so the following list is only illustrative. Buy the products in the DIY store or specialty store of your trust!
It's important to note that although an IP66 enclosure is waterproof against hose-directed water, rain or snow, it's not intended to be submerged in water.

Frequently, it is also useful to buy starter packages, in which, for example, the basic device and individual drippers and manifold are already present.
## WATER TON
Requirements:
- < 100 €
- 300-500 Litres
- Robust and UV resistant
- Dimensions: max. 1m x 1m (4x 50cm)

## WATER PUMP
Requirements:
- < 200 €
- Pump drive: Self-priming __Jet-Pump__ (The difference between jet pumps and multistage centrifugal pumps is that jet pumps are self-priming. Multistage centrifugal pumps are normal priming, i.e. the suction line and the pump must be completely filled with water in order to be able to pump water.)

- Suction connection: 1/2-Zoll
- Minimum self-suction height: > 4 metres
- Built-in float switch to prevent the pump from running dry
- Low operating noise level (out of consideration for neighbors)
- Optional: integrated non-return valve

- Measuring temperature and humidity with a FS200-SHT10 sensor
## REQUIREMENTS
- Wemos D1 Mini (should work with other Arduino microcontrollers too)
- PlatformIO or Arduino IDE (for Arduino IDE you have to move files from /src to root-folder)
- MQTT Broker such as the Mosquitto MQTT Broker (https://mosquitto.org/)

### INTEGRATION OF A SWITCH
After some research, it is basically possible **in parallel to the relay to switch a switch**, which is suitable for outdoor use. This allows the pump to be switched on and off outside the watering periods.

## SENSORS
### HUMIDITY AND TEMPERATURE FS200-SHT10
Requirements:
- Measuring range 0 ... 100% rH, -20 ... +100°C
- Splash-proof for outdoor applications
**Sharainn soil moisture sensor, FS200-SHT10 3.3-5 V soil temperature and humidity sensor probe** - 20 100-100 ℃ 0-100% relative humidity sensor for agricultural greenhouses.

#### DESCRIPTION
The soil temperature and humidity probe, using the original temperature and humidity sensors as the core component, can be directly connected to the single chip microcomputer for use. With very high consistency, it can be completely interchangeable. The probe has the characteristics of temperature resistance, pressure resistance, loss of ability, suitability for agricultural greenhouse, flowers, nursery, lawn and other needs to detect soil temperature and humidity.

### UNDERSTANDING RELAY HIGH AND LOW
To switch the relay it is necessary to define the two GPIOs of the Arduino with pinMode as output.
By default, the Arduino microcontroller then switches the output to LOW, which means that the connected relay is switched on, i.e. the pump is running. To prevent this, the PIN must be set to HIGH **before** defining it as an output.
```
digitalWrite(relayPump, HIGH);
pinMode(relayPump, OUTPUT);
digitalWrite(relaySocket, HIGH);
pinMode(relaySocket, OUTPUT);
```

## AUTOMATION WITH NODE-RED
If the pump can now be switched on and off via the MQTT Broker from anywhere in the world, it is naturally obvious to implement automation here. To cover this logic with the Arduino itself and to write it in C-code is quite feasible, but I decided to use the Framwork Node-RED for this, because here workflows can be created without much programming effort.
### NODE-RED MODULES REQUIREMENTS
- node-red-contrib-schedex
- node-red-contrib-stoptimer
- node-red-contrib-telegrambot (optional if you would like to get status messages)
### NODE-RED FLOW
Node-RED works with so-called flows, which can be imported and exported.
An example of a flow can be found in **flows.json** in the github repository.

## CONTROL AND MANAGEMENT
### MQTTDASH
A really outstanding Android app is MQTTDash, which establishes a connection to MQTTBroker, where buttons, graphs, switches, text fields, images and much more can be embedded. Take a look at the screenshot below.
https://play.google.com/store/apps/details?id=net.routix.mqttdash&hl=en
### TELEGRAM
For status messages I use Telegram, here is a well described API and corresponding plugins for Node-RED.
