When a family wanna take a overseas holiday for a week. They have some problems that they can’t left their garden just like that in the summer season or the plants will die. Meanwhile, the garden is already have an automatic watering system but, they seems still too worry about their garden.
With this simple plant monitoring system they no need to worry about their garden anymore. By using the Internet Of Things (IoT) Plant Monitoring system for the garden they can always monitoring the garden anytime and anywhere they want through Mobile Apps called Blynk.
Soil moisture sensor works by pluging the sensor into theplant pot or soil then the sensor will read the soil moisture. Meanwhile, DHT 22is for calculating the air temperature and air humidity.
Software Os and Apps
The schematic is simple, follow the instructions below.
- Pin A0 toA0 on Soil Moisture Sensor
- GNDto GNDon Soil Moisture Sensor
- 3V3to VCC on Soil Moisture Sensor
- Pin D1 tomiddle side of DHT 22
- GNDto right side of DHT 22
- 3V3to left side of DHT 22
- GND to groundside of Breadboard
Soil moisture sensor using Analog pin (A0), DHT 22 usingGPIO 5 pin, and 3 Leds using GPIO 14 for RED, GPIO 12 for GREEN, and GPIO 13for BLUE on ESP8266. Setup the ESP8266 board to connect to Wifi by define yourSSID, Password and Auth Code for Blynk. For the Auth Code you need to download Blynk Apps on your Mobile Phone then create a new project on Blynk Apps and find your Auth Code in project setting.
