Story

Building Your Moisture Meter Made Easy with the Web Flashing Tool!

Introduction:

Are you a gardening enthusiast who wants to take your green thumb to the next level? Have you ever wished to have a reliable moisture meter that can help you keep your plants thriving without the hassle of learning how to code or delve into technical complexities? Look no further! In this super hackster.io story, we'll guide you through building your very own moisture meter using a capacitive soil moisture sensor, an ESP8266, and an OLED screen. The best part? You won't need any coding knowledge as we have a special web flashing tool to simplify the process for you!

Step 1: Meet the Components

Before we dive into the project, let's introduce the components you'll be using. We have chosen the capacitive soil moisture sensor for its accuracy and simplicity. The ESP8266, a versatile Wi-Fi-enabled microcontroller, will act as the brain of our moisture meter. To display moisture levels in an easy-to-read format, we have included a vibrant OLED screen. Lastly, the triple adapter will help you power all the components efficiently.

ATRIPLER, AN OLED, CAPACITIVE SENSOR AND AN ESP8266

I would recommend you get all these components from Chipglobe shop at an affordable price

Step2: Assembling the Moisture Meter

With the web flashing tool in hand, let's move on to assembling the moisture meter. Don't worry; we'll provide clear visual instructions to guide you through the process. Connect the capacitive soil moisture sensor to the ESP8266 using the triple adapter

GND to GND on the tripler.
VCC to 3v3 on the tripler.
AUOT to A0 pin on the tripler.

Attach the OLED screen to display the moisture levels.

Here is how the set up should look like

Step 3: Web Flashing Tool - Your Coding-Free Solution

Our main goal with this project is to make it accessible to everyone, regardless of their coding background. To achieve this, we've developed a user-friendly web flashing tool. This tool allows you to upload the necessary code and configurations to your ESP8266 without writing a single line of code!

Simply connect your setup using a USB cable, Access the web flashing tool and click install you'll have your ESP8266 ready to go in no time.

Step 4: Power it Up!

Now that you've assembled the moisture meter, it's time to power it up and witness the magic unfold. Once you turn on the device, the OLED screen will light up, and the moisture sensor will start gathering data from the soil.

Step 5: Reading Moisture Levels

Using the OLED screen, you can easily read the moisture levels of your plants. The display will show intuitive icons or a numerical value representing the moisture content in the soil. No need to interpret complex graphs or learn how the capacitive moisture sensor works; the moisture meter does all the heavy lifting for you!

Conclusion:

Congratulations! You've successfully built your very own moisture meter without the need to code or understand the technicalities behind the capacitive soil moisture sensor. With the help of our innovative web flashing tool, you can enjoy hassle-free plant care and ensure your green friends are always thriving. Happy gardening!

Disclaimer: Always be cautious while handling electronic components and ensure proper safety measures are taken during the construction of the project.

Code

Find here in Arduino code

#include <SPI.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define OLED_RESET 0 
Adafruit_SSD1306 display(OLED_RESET);

const int dry = 0; // value for dry sensor
const int wet = 100; // value for wet sensor

void setup()
{ 
  Serial.begin(9600);
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
}

void loop()
{
  // Clear the buffer.
  display.clearDisplay();
  display.setTextSize(1);
  display.setCursor(40, 10);
  display.setTextColor(WHITE);
  
  int sensorVal = analogRead(A0);

  // Sensor has a range of 0 to 100
  // We want to translate this to a scale or 0% to 100%
  int percentageHumididy = map(sensorVal, wet, dry, 100, 0); 

   display.println("Moisture: ");
   display.setTextSize(1);
   display.setCursor(40, 21);
   display.print(percentageHumididy);
   display.println("%");
   display.display();
   delay(1000);
}
