When the environment reaches the set temperature, the onboard relay activates or deactivates a connected device such as a heater, fan, or compressor. You can configure the controller to either turn on when the temperature rises (cooling mode) or falls (heating mode), depending on your needs.The included NTC temperature sensor provides stable and accurate readings, which are continuously displayed on the bright red 3-digit LED display. The user interface consists of three onboard push buttons (SET, , -) to configure temperature setpoints, hysteresis values, and delay parameters.��️ Applications & Use Cases:Thanks to its versatility, the W1209 module is widely used in both home and professional setups. Popular applications include:✅ Incubators – Control the temperature for hatching eggs✅ Aquariums – Maintain optimal water temperature for aquatic life✅ Greenhouses – Automate heating or cooling systems for plant growth✅ Pet Habitats – Regulate temperature in reptile enclosures✅ DIY Smart Fans – Automatically turn fans on/off at specific temperatures✅ Fermentation Chambers – Maintain proper heat during brewing or food curing✅ Server Cabinets – Control cooling fans to avoid overheating✅ 3D Printer Enclosures – Maintain temperature stability during printing⚙️ Technical Specifications:Input Voltage: 12V DCTemperature Range: -50°C to 110°CControl Accuracy: ±0.1°CSensor Type: NTC waterproof thermistorRelay Output: 1-channel (up to 20A, 14V DC / 10A 250V AC)Display Type: 3-digit 7-segment LEDDimensions: Approx. 48mm x 40mm x 15mmPower Consumption: Minimal when idleMounting: Screw holes for easy panel integration�� Setup Instructions:Connect 12V DC power to the input terminals (VCC and GND).Connect your load (fan, heater, pump, etc.) to the relay output terminals.Insert the temperature sensor probe into the sensor terminal.Use the SET button to adjust temperature limits.Use and – buttons to fine-tune setpoint values and hysteresis.For added safety, the module features a delay function to avoid frequent relay switching and protect your devices.�� Why Buy from Electroxbd?At Electroxbd, we ensure all our temperature controller modules are:✅ 100% tested and quality-checked✅ Shipped quickly to any location in Bangladesh✅ Available in retail or wholesale quantities✅ Backed by excellent after-sales support✅ Priced affordably for students and professionalsOur store is based in Rajshahi, and we proudly support engineers, hobbyists, and businesses with reliable electronic parts and modules.�� Need Assistance?Contact us via WhatsApp at 01600334238 for expert advice, bulk pricing, or technical help with your automation or DIY projects.�� Order Now:Take control of your heating or cooling needs with the W1209 DC 12V Temperature Controller Module – now available at Electroxbd.com.
