W1209 Temperature Controller Price in Pakistan | Digital Controller

The W1209 Temperature Controller is a popular and affordable temperature regulation device that is commonly used in various electronic and home applications, such as incubators, refrigerators, and aquariums. It is a small, compact, and versatile microcontroller-based unit designed to maintain a set temperature by controlling heating or cooling elements.Chip.pk Give Best W1209 Temperature Controller Price in Pakistan.

Key Features:

1. Temperature Range: Typically, it supports a temperature range from -50°C to +110°C, but this can vary depending on the version or sensor used.
2. Digital Display: It features an LED screen that shows the current temperature and settings, which makes it easy to monitor.
3. Adjustable Setpoint: The user can set a desired target temperature, and the controller will turn the heating or cooling element on/off to maintain that temperature.
4. Relay Output: The controller can activate a relay that controls high-power devices like heaters, fans, or refrigeration units.
5. Hysteresis Setting: This allows you to set a margin (hysteresis) around the target temperature, ensuring the system doesn’t constantly turn on and off when the temperature fluctuates around the set point.
6. Alarm Functions: Some models come with over-temperature and under-temperature alarms for added safety.
7. Temperature Sensor: Typically, the W1209 uses an NTC thermistor as its temperature sensor to detect the temperature in the environment.

How It Works:

1. Temperature Sensing: The W1209 has a temperature sensor (usually an NTC thermistor) that constantly monitors the surrounding temperature.
2. Set Temperature: The user can input the desired temperature (setpoint) through the buttons on the controller.
3. Control Action: Once the current temperature deviates from the setpoint by a certain margin (defined by the hysteresis), the W1209 will take action:
   • If the temperature is too high, it will activate a cooling system (e.g., fan or cooler).
   • If the temperature is too low, it will turn on a heating element (e.g., heater or bulb).
4. Relay Switching: The relay is the component that actually switches the external heating or cooling system on or off. It works based on the logic defined by the controller’s settings.
5. Maintaining Temperature: The controller continually monitors the temperature and adjusts the relay as needed to maintain the set temperature within the desired range.

Common Applications:

• Incubators: To regulate the temperature for hatching eggs.
• Aquarium Heaters: To maintain a stable water temperature for fish or other aquatic life.
• Home Brewing: For controlling fermentation temperatures in brewing beer or wine.
• Refrigerators: To maintain precise temperatures for food or other sensitive items.

Advantages:

• Simple to Use: The interface is generally straightforward, with buttons for setting the temperature and adjusting parameters.
• Cost-Effective: It’s a budget-friendly option for DIY projects that require temperature control.
• Versatile: Works for both heating and cooling systems, making it adaptable to various scenarios.

Additional Features and Functions:

1. Relay Output for Switching:

   • The W1209 controller is equipped with a relay that acts as a switch to control external devices such as a heater or a cooling fan. The relay is often rated for higher currents (e.g., 10A or more), so it can handle the load of most devices connected to it.
   • When the temperature crosses the setpoint (either above or below), the relay activates the connected device to either cool down or heat up the environment.

2. Temperature Calibration:

   • The controller has an option for calibration. If you believe that the temperature readings are not accurate (which can sometimes happen due to the sensor’s positioning or a faulty sensor), you can adjust the readings by adding or subtracting a value in the settings.

3. Hysteresis Settings (Differential Control):

   • Hysteresis refers to the temperature difference allowed between turning the device on and off around the setpoint. This prevents the relay from constantly toggling due to small fluctuations in the temperature, which could cause wear and tear on both the controller and the connected device.
   • For example, if the setpoint is 25°C and the hysteresis is set to 2°C, the heating or cooling device will be activated at 23°C (for heating) and will turn off at 27°C (for cooling).

4. Input and Output Terminals:

   • The W1209 controller typically has input terminals for connecting a temperature sensor (e.g., an NTC thermistor), and output terminals for connecting external devices like heaters, fans, or refrigeration units via the relay.
   • The sensor is usually a 1-wire connection, and the output terminals are for the relay switch (usually marked as NO for Normally Open and COM for Common).

5. Temperature Units (Celsius/Fahrenheit):

   • The display on the W1209 can show the temperature in either Celsius (°C) or Fahrenheit (°F), which you can switch between in the settings.

6. Low Power Consumption:

   • The controller is designed to be energy-efficient. It has low power consumption, making it ideal for applications where constant monitoring is required without draining a lot of energy.

7. Display Settings:

   • The LED screen shows the current temperature and the setpoint temperature. It’s easy to read and shows whether the device is in heating or cooling mode.
   • Some versions of the W1209 allow the display to toggle between showing the current temperature and the set temperature.

How to Use the W1209 Temperature Controller:

1. Wiring the Controller:

   • Sensor Wiring: The temperature sensor (typically an NTC thermistor) will be connected to the sensor input pins on the W1209 controller.
   • Device Wiring: A device (such as a heater or cooling fan) will be connected to the relay output pins on the controller. One pin is the Common (COM), and the other pin is the Normally Open (NO). The device should be connected to the NO pin, and the COM pin should be connected to the power supply.

2. Configuring the Controller:

   • After wiring the sensor and device, power on the W1209.
   • Use the buttons on the front of the controller to set the target temperature (setpoint), adjust the hysteresis, and choose between heating or cooling modes.
   • Some models also allow you to set alarms for over-temperature or under-temperature conditions.

3. Setting the Temperature:

   • Press the Set button to enter the setpoint temperature, and use the Up and Down buttons to adjust it.
   • For hysteresis settings, go into the menu (if available) and select your desired range for when the device should turn on/off.

4. Calibration:

   • If the controller shows an inaccurate reading compared to a known thermometer, use the calibration function to adjust the readings.

5. Power Up:

   • Once set up, the controller will automatically turn the connected device (heater or cooler) on or off based on the ambient temperature compared to the setpoint and the hysteresis.
