XH-M452 Digital Temp & Humidity Controller

Dual Simultaneous Temperature & Humidity Control: Onboard dual relay outputs independently command heating/cooling and humidification/dehumidification circuits in real time.

12V DC Low-Voltage Operation: Operates safely on a 12V DC input, making it ideal for custom electronic enclosures, battery-backed setups, and off-grid automation systems.

Dual Digital LED Display Panels: Vibrant dual LED screens continuously display real-time temperature (Red LED) and relative humidity (RH, Blue LED) side-by-side.

Bundled High-Precision Combo Sensor: Includes an integrated temperature and relative humidity probe for responsive, accurate environmental sensing.

Intuitive Push-Button Calibration: Features standalone adjustment buttons per channel to quickly program start temperatures, stop temperatures, and humidity setpoints.

Board Material: High-grade FR-4 glass-epoxy PCB with surface-mount LED display modules, heavy-duty switching relays, and screw terminal blocks.

Technical Specifications:

Operating Voltage: 12V DC.

Temperature Range: -20°C – +60°C.

Humidity Range: 0% – 99% RH.

Relay Output Capacity: 10A / 12V DC or 10A / 250V AC.

Board Color: Blue PCB with Black Relays.

Usage Advice: Verify 12V DC supply polarity before applying power; tighten terminal block screws securely to prevent resistive heating.

Maintenance: Keep PCB surface free from dust, moisture, and flux residue; ensure the sensor casing remains clean for unhindered airflow.

Essential Open-Frame Climate Engine: Position as a versatile open-board module for custom incubators, DIY terrariums, mushroom growing setups, and server rack thermal management.

Highlight High-Precision Dual Monitoring: Emphasize how a single compact board simultaneously displays and controls both temperature and humidity without requiring extra microcontroller programming.
