Description

What it is

The Soil Moisture Sensor is a detector used to measure the moisture present in the ground. This device is ideal for agritech and automation projects, allowing farmers and makers to monitor soil conditions in real-time.

Features

• Sensor to measure soil moisture

What it is for

The sensor can be used to create an automatic irrigation system with Arduino and a pump. It is compatible with Arduino and ESP, making it easy to integrate into DIY projects.

Tutorial: How to use Soil Moisture Sensor

The soil moisture sensor measures the moisture level in the ground, useful for farmers and makers who want to monitor soil conditions in real-time.

What you need

• Soil Moisture Sensor
• Arduino
• Connection cable
• 10kΩ resistor

Steps

1. 1. Connect the sensor to pin A0 of Arduino.
2. 2. Connect a 10kΩ resistor between VCC and GND of the sensor.
3. 3. Download the provided code.
4. 4. Upload the code to Arduino.
5. 5. Check the resistor value of the sensor on the datasheet.
6. 6. Once connected, the sensor will send analog values.
7. 7. Use a library to read the values.
8. 8. Verify accuracy with a physical hygrometer.

Example code

```void loop() {  int sensorValue = analogRead(A0);  Serial.println(sensorValue);}```

Mini project

Create an automatic irrigation system with Arduino and a pump. In 30 minutes, you can connect the sensor to a timer and a pump.

Common mistakes

• Connect the sensor directly to VCC without a resistor.
• Skip checking the datasheet.
• Do not use a library to read the values.
• Ignore the accuracy of the sensor

Recommended accessories

• Pump
• Timer
• Physical hygrometer
• Connection cable
