Product Description

Achieve total environmental control with the XH-M452 Temperature and Humidity Controller Module. This professional-grade dual-purpose board functions as both a high-precision thermostat and a hygrostat. It allows you to monitor and control heating/cooling and humidification/dehumidification systems simultaneously. At Robogears, we recommend the XH-M452 for specialized applications like egg incubators, mushroom farming, and greenhouse climate control. The module features two bright LED displays for real-time monitoring and four tactile buttons for setting precise start and stop thresholds. Whether you are building an automated terrarium or a sensitive laboratory storage unit at your Pimpri workshop, the XH-M452 provides a reliable industrial-grade interface for climate management.

Detailed Key Features

  • Independent Dual Control: The left side of the board manages temperature, while the right side manages humidity, with separate relay outputs for each.

  • Heating/Cooling Modes: Set the start temperature higher than the stop temperature for cooling, or lower for heating.

  • Humidify/Dehumidify Modes: Easily configurable for humidifying (start humidity < stop) or dehumidifying (start humidity > stop).

  • High-Precision Sensor: Includes a pre-calibrated sensor probe on a 1-meter cable, allowing you to place the sensor inside an enclosure while the controller remains accessible.

  • Non-Volatile Memory: All settings are automatically saved, ensuring the controller resumes your specific parameters after a power outage.

All Technical Details

  • Button Controls:

    • Temp Buttons: "+" sets start temp; "-" sets stop temp.

    • Humidity Buttons: "+" sets start humidity; "-" sets stop humidity.

  • Wiring Interface:

    • Input: 12V DC Power.

    • Output 1 (Temp): Relay switch for heater/cooler.

    • Output 2 (Humidity): Relay switch for humidifier/fan.

  • LED Status: Integrated indicator lights show which relay is currently active.

  • Applications: Greenhouse ventilation, cigar humidors, industrial drying rooms, and smart home HVAC.

Prototyping & Engineering Tips (Robogears Exclusive)

  • The "Dry Contact" Rule: At our Pimpri facility, we always remind makers that the relay outputs are switches, not power sources. You must loop your device’s power line through the relay terminals.

  • Calibrating the Sensor: If the reading differs from a professional thermometer, you can calibrate it by holding both "+" and "-" buttons of the respective channel to enter the offset menu.

  • Sensor Protection: While the probe is high-quality, avoid submerging it in water. For high-humidity environments (like foggers), ensure the sensor is placed away from direct mist to prevent condensation from affecting long-term accuracy.

  • Power Supply Stability: Ensure your 12V DC adapter can provide enough current for the relays to click reliably (at least 500mA is suggested).

Package Includes

  • 1 x XH-M452 Temperature and Humidity Controller Module

  • 1 x Integrated Temperature/Humidity Sensor Probe (1-meter cable)
