If you are looking for an affordable and reliable way to control temperature, the W1209 temperature controller is an excellent choice. This device is easy to use, programmable, and can control both heating and cooling processes. In this beginner's guide, we will walk you through everything you need to know to get started with the W1209 temperature controller.
What is the W1209 Temperature Controller?
The W1209 temperature controller is a small electronic device that uses a microcontroller to regulate temperature. It has a digital display and can be programmed to control heating and cooling processes. It can work with a variety of temperature sensors, including NTC thermistors, which are included with the device.
The W1209 temperature controller is versatile and can be used in many applications, including aquariums, terrariums, incubators, and greenhouses. It is also useful for controlling the temperature of homebrewing setups, soldering irons, and other DIY projects.
How Does the W1209 Temperature Controller Work?
The W1209 Temperature Controller works by using a thermistor to measure the temperature of the system. The thermistor is a resistor whose resistance changes with temperature. As the temperature of the system changes, the resistance of the thermistor changes, which is then converted into a voltage reading by the controller.
The W1209 controller then compares the measured temperature to the set temperature and turns a relay on or off to control the system's heating or cooling elements. For example, if the measured temperature is lower than the set temperature, the controller will turn on the heating element until the set temperature is reached. If the measured temperature is higher than the set temperature, the controller will turn on the cooling element until the set temperature is reached.
How to Use the W1209 Temperature Controller?
Using the W1209 Temperature Controller is relatively straightforward. Here are the steps to follow:
1. Connecting the Temperature Sensor
The temperature sensor should be connected to the W1209 temperature controller using the two-pin connector provided. The red wire should be connected to the positive terminal, and the black wire should be connected to the negative terminal. The sensor should then be placed in the area where you want to monitor the temperature.
2. Connecting the Power Source
The W1209 temperature controller can be powered by a 12V DC power supply, such as a wall adapter or a battery. The power source should be connected to the terminals labeled "VIN" and "GND" on the controller.
3. Connecting the Heating or Cooling Device
The W1209 temperature controller has two output relays that can be used to control heating and cooling devices. The heating device should be connected to the terminals labeled "OUT1," and the cooling device should be connected to the terminals labeled "OUT2."
Programming the W1209 Temperature Controller
The W1209 temperature controller is easy to program. Follow the steps below to set the desired temperature setpoint and other parameters:
Step 1: Press the "SET" button. The temperature setpoint will begin to blink on the screen.
Step 2: Use the "UP" and "DOWN" buttons to adjust the temperature setpoint. The temperature can be set to a range of -50°C to 110°C.
Step 3: Press the "SET" button again to save the temperature setpoint.
Step 4: Use the "UP" and "DOWN" buttons to set the desired hysteresis value. Hysteresis is the difference between the setpoint and the point at which the output device is activated. A higher hysteresis value means that the output device will turn on and off less frequently, which can help prolong its lifespan.
Step 5: Set the alarm temperature by pressing the "SET" button and adjusting the temperature with the "UP" and "DOWN" buttons.
Step 6: Set the delay time for the alarm. This is the time that the controller will wait before activating the alarm. Use the "UP" and "DOWN" buttons to set the desired delay time.
Monitoring the Temperature
Once the W1209 temperature controller is set up and programmed, it will start monitoring the temperature and activating the output relays to control the heating and cooling devices. The current temperature can be viewed on the digital display.
Conclusion
The W1209 temperature controller is an affordable and versatile way to control temperature in a variety of applications. With its programmable settings and easy-to-use interface, it is an excellent choice for beginners and DIY enthusiasts.
