XH-M452 Dual Digital Temperature and Humidity Controller Module – High-Precision 12V DC Thermostat and Hygrostat with SHT20 Sensor for Incubators, Greenhouses, and HVAC Automation

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.
