ESP32-Based Automated Plant Watering System with Environmental Monitoring

This is an environmental monitoring and control system designed to read soil moisture and air temperature/humidity, and to actuate a fan and water pump for maintaining desired conditions. The ESP32 microcontroller serves as the central processing unit, interfacing with sensors, an OLED display, and controlling actuators via a 2-channel relay. Power is supplied by a 12V battery, with the ESP32 managing power distribution to the components.

How to Use the SH-T10 in a Circuit

1. Power Supply: Connect the VCC pin to a power supply within the range of 2.4V to 5.5V. Connect the GND pin to the ground of the power supply.
2. I2C Communication: Connect the SDA (data) and SCL (clock) pins to the corresponding I2C pins on your microcontroller (e.g., Arduino UNO).
3. Pull-up Resistors: Ensure that the SDA and SCL lines have pull-up resistors (typically 4.7kΩ) to the VCC.

Important Considerations and Best Practices

• Power Stability: Ensure a stable power supply to avoid fluctuations that could affect sensor readings.
• I2C Address: The default I2C address for the SH-T10 is 0x44. Ensure no address conflicts on the I2C bus.
• Environmental Factors: Avoid placing the sensor in direct sunlight or near heat sources to ensure accurate readings.
• Calibration: Although the SH-T10 is factory-calibrated, periodic calibration may be necessary for critical applications.

Example Code for Arduino UNO

#include <Wire.h>

#define SH_T10_ADDRESS 0x44

void setup() {
  Wire.begin();
  Serial.begin(9600);
  delay(1000); // Allow some time for the sensor to initialize
}

void loop() {
  float temperature, humidity;
  if (readSensorData(temperature, humidity)) {
    Serial.print("Temperature: ");
    Serial.print(temperature);
    Serial.println(" °C");
    Serial.print("Humidity: ");
    Serial.print(humidity);
    Serial.println(" %RH");
  } else {
    Serial.println("Failed to read from SH-T10 sensor");
  }
  delay(2000); // Wait for 2 seconds before the next reading
}

bool readSensorData(float &temperature, float &humidity) {
  Wire.beginTransmission(SH_T10_ADDRESS);
  Wire.write(0xE5); // Command to read temperature and humidity
  if (Wire.endTransmission() != 0) {
    return false; // Transmission error
  }
  delay(20); // Wait for the sensor to process the command
  Wire.requestFrom(SH_T10_ADDRESS, 6);
  if (Wire.available() != 6) {
    return false; // Not enough data received
  }
  uint16_t rawTemp = (Wire.read() << 8) | Wire.read();
  uint16_t rawHumidity = (Wire.read() << 8) | Wire.read();
  temperature = -45 + 175 * (rawTemp / 65535.0);
  humidity = 100 * (rawHumidity / 65535.0);
  return true;
}

Troubleshooting and FAQs

Common Issues Users Might Face

1. No Data from Sensor:

   • Solution: Check the wiring connections, especially the SDA and SCL lines. Ensure pull-up resistors are in place.

2. Inaccurate Readings:

   • Solution: Ensure the sensor is not exposed to direct sunlight or heat sources. Verify the power supply is stable.

3. I2C Address Conflict:

   • Solution: Ensure no other devices on the I2C bus share the same address (0x44). If necessary, change the address of the conflicting device.

Solutions and Tips for Troubleshooting

• Check Connections: Ensure all connections are secure and correct.
• Use a Multimeter: Verify the voltage levels on the VCC and GND pins.
• Library Compatibility: Ensure you are using a compatible library for the SH-T10 sensor.
• Sensor Placement: Place the sensor in an environment representative of the area you wish to measure.
