XH-M214 Soil Moisture Control Module Digital Display

Description

What it is

The XH-M214 Soil Moisture Control Module Digital Display is an Arduino module that measures soil moisture. It allows real-time monitoring of soil moisture levels through an integrated digital display.

Features

• Integrated digital display
• Measures soil moisture
• Compatible with Arduino
• SKU: ARD0011334
• Price: 8.29 €

What it is for

The XH-M214 module is ideal for automatic irrigation or soil moisture monitoring projects. You can connect it to an Arduino and program it to turn on an irrigation system when the moisture level drops below a certain threshold.

Tutorial: How to use XH-M214

The XH-M214 digital display allows you to easily monitor soil moisture in an irrigation or cultivation project. Useful for beginners and those who want precise moisture control.

What you need

• Arduino or compatible
• Mass connections
• 5V power lead
• Display XH-M214

Steps

1. 1. Connect the display to the Arduino using the following pins: VCC to 5V, GND to ground, D4 to a digital pin on the Arduino.
2. 2. Download and install the Adafruit_SSD1306 library.
3. 3. Write the following code to initialize the display:
4. 4. `#include `
5. 5. `Adafruit_SSD1306 display(SSD1306_I2C_ADDRESS, 0x3C);`
6. 6. `void setup() {`
7. 7. ` display.begin(SSD1306_SWITCHCAPVCC, 0x3C);`
8. 8. ` display.display();`
9. 9. `}`
10. 10. `void loop() {`
11. 11. ` display.clearDisplay();`
12. 12. ` display.setTextSize(1);`
13. 13. ` display.setTextColor(SSD1306_WHITE);`
14. 14. ` display.setCursor(0, 0);`
15. 15. ` display.println(“Soil humidity”);`
16. 16. ` display.display();`
17. 17. `}`

Mini project

Build an automatic irrigation system. Connect the XH-M214 to an Arduino and monitor soil moisture. Configure a relay to turn on an irrigation system when the moisture level drops below a certain threshold.

Common mistakes

• Forget to connect VCC to 5V.
• Connect the display to a non-digital pin.
• Fail to install the necessary library.
• Forget to initialize the display.

Recommended accessories

• Relay
• Soil moisture sensors
