Hardware

Microcontroller: Esp32 NodeMCU

Sensors:

• FC-37 (Rain Sensor)
• Capacitive soil moisture sensor v1.2 (Soil moisture Sensor)
• DS18B20 (Soil temperature Sensor)
• BMP280 (Temperature, Pressure, Altitude Sensor)
• UVM30A (UV Sensor)
• ARD SEN LDR (Light intensity Sensor)

Actuators:

• 2 x FUNGWAN MG 996R (Servo Motor)
• 3-Wire Fan (Fan)
• 3 x 5v Relays (Relay)
• 230v Lamp (Lamp)

Dependencies

<ESP32Servo.h> <Adafruit_BMP280.h> <Adafruit_Sensor.h> <Wire.h> <OneWire.h> <DallasTemperature.h> <SPI.h> <BH1750.h> <EspMQTTClient.h>

Application Steps

• Build the Greenhouse-Casing
• Connect the sensor to the Micro-Controller (take a look at the datasheets to not overvolt one of the Sensors/Esp32; The pinout is in the code!)
• Flash software onto the Esp32 with the Arduino IDE
• Setup a Node-RED Server and import JSON
