How to Use Incubator Controller: Examples, Pinouts, and Specs

The Incubator Controller (HM68 / XM18) is a versatile device designed to regulate and maintain critical environmental conditions such as temperature and humidity within an incubator. This component ensures optimal growth and development of biological samples or organisms by providing precise control over these parameters. It is widely used in applications such as poultry egg incubation, laboratory experiments, and other biological research requiring controlled environments.

• Poultry egg incubation for hatching
• Laboratory experiments requiring controlled temperature and humidity
• Biological research involving cell cultures or microorganisms
• Industrial applications for environmental simulation

The following table outlines the key technical details of the Incubator Controller:

The Incubator Controller has a set of input and output terminals for connecting sensors, power, and controlled devices. The pin configuration is as follows:

1. Power Connection: Connect the AC power supply to the AC Input (L) and AC Input (N) terminals. Ensure the voltage matches the controller's input range (110V-220V).
2. Sensor Connection: Attach the temperature sensor to the Temp Sensor terminal and the humidity sensor to the Humidity Sensor terminal.
3. Load Connection: Connect the heating, cooling, humidifying, and dehumidifying devices to their respective output terminals.
4. Configuration: Use the digital LED display and buttons to set the desired temperature and humidity levels. Refer to the user manual for detailed programming instructions.
5. Operation: Once configured, the controller will automatically regulate the connected devices to maintain the set environmental conditions.

• Ensure all connections are secure and insulated to prevent electrical hazards.
• Use devices with current ratings within the controller's maximum load capacity (10A).
• Place the sensors in appropriate locations within the incubator for accurate readings.
• Avoid exposing the controller to water or excessive moisture to prevent damage.
• Regularly calibrate the sensors for optimal performance.

While the Incubator Controller is a standalone device, it can be interfaced with an Arduino UNO for advanced monitoring or control. Below is an example code snippet for reading temperature and humidity data from the controller's sensors:

#include <Wire.h>

// Define analog pins for temperature and humidity sensors
const int tempSensorPin = A0; // Connect Temp Sensor to A0
const int humiditySensorPin = A1; // Connect Humidity Sensor to A1

void setup() {
  Serial.begin(9600); // Initialize serial communication
  pinMode(tempSensorPin, INPUT); // Set temperature sensor pin as input
  pinMode(humiditySensorPin, INPUT); // Set humidity sensor pin as input
}

void loop() {
  // Read analog values from sensors
  int tempValue = analogRead(tempSensorPin);
  int humidityValue = analogRead(humiditySensorPin);

  // Convert sensor values to meaningful units (example conversion)
  float temperature = (tempValue / 1023.0) * 100.0; // Convert to °C
  float humidity = (humidityValue / 1023.0) * 100.0; // Convert to %RH

  // Print the readings to the Serial Monitor
  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.println(" °C");

  Serial.print("Humidity: ");
  Serial.print(humidity);
  Serial.println(" %RH");

  delay(1000); // Wait for 1 second before next reading
}

Note: The above code assumes the sensors output analog signals. If the sensors are digital, refer to their datasheets for proper interfacing.

1. Controller Not Powering On:

   • Check the AC power supply and ensure proper voltage is supplied.
   • Verify that the live and neutral wires are connected correctly.

2. Inaccurate Temperature or Humidity Readings:

   • Ensure the sensors are properly connected and placed in the correct location.
   • Calibrate the sensors if readings are consistently off.

3. Relay Outputs Not Activating:

   • Verify that the connected devices are functional and within the controller's load capacity.
   • Check the configuration settings to ensure the setpoints are correct.

4. Display Malfunctioning:

   • Inspect for loose connections or damaged components.
   • Restart the controller and check if the issue persists.

• Always disconnect the power supply before inspecting or modifying connections.
• Use a multimeter to check for continuity and proper voltage levels at the terminals.
• Refer to the manufacturer's user manual for advanced troubleshooting steps.
• If the issue cannot be resolved, contact the supplier or manufacturer for support.

By following this documentation, users can effectively utilize the Incubator Controller (HM68 / XM18) to maintain precise environmental conditions for their applications.
