XY-TR01 Digital Temp Humidity Controller DC 12V LCD Relay Module

XY-TR01 Digital Temperature & Humidity Controller — DC 12V 10A LCD Relay Module

Take precise control of your environment with the XY-TR01 Temperature & Humidity Controller. This compact relay module features a high-definition LCD display and dual-channel control for both temperature and humidity, making it ideal for workshops, incubators, grow rooms, print facilities, control cabinets, and more. With 0.1°C / 0.1% RH accuracy and automatic mode identification, it takes the guesswork out of climate management.

Key Features

• Dual Monitoring: Measures temperature and humidity simultaneously with a single integrated sensor.
• HD LCD Display: Clear, easy-to-read digital readout of real-time temperature and humidity values.
• Auto Mode Detection: Automatically identifies Heating mode (H) or Cooling mode (C) based on your start/stop temperature settings — no manual switching required.
• High-Precision Control: 0.1°C and 0.1% RH accuracy for tight, reliable environmental management.
• 10A Relay Output: Drives heaters, coolers, humidifiers, dehumidifiers, and other equipment directly.
• UART Support: Compatible with microcontroller projects and serial communication setups.
• Micro USB Input: Convenient power and data interface.
• Temperature Calibration: Offset correction function (−10.0 to +10°C) to compensate for sensor drift over time.

How It Works — Temperature Control Modes

Cooling Mode (C): When Start temperature is set higher than Stop temperature, the system enters Cooling mode. The relay activates (red LED on) when the measured temperature reaches or exceeds the Start value, and deactivates when it drops to or below the Stop value.

Heating Mode (H): When Start temperature is set lower than Stop temperature, the system enters Heating mode. The relay activates when temperature falls to or below the Start value and deactivates once the Stop temperature is reached.

Settings are saved automatically after 6 seconds of inactivity — simply hold TM+ or TM− for 3 seconds to enter the respective start/stop temperature settings menu.

Frequently Asked Questions

Q: What is the operating voltage of the XY-TR01 Temperature Humidity Controller?

A: The XY-TR01 operates on DC 12V and supports up to 10A relay output current, making it compatible with a wide range of 12V-powered heating, cooling, humidifying, and dehumidifying equipment.

Q: Can the XY-TR01 control both a heater and a cooler automatically?

A: Yes. The controller automatically identifies whether to operate in Heating mode (H) or Cooling mode (C) based on how you configure the start and stop temperature setpoints — no manual mode switching is needed.

Q: Does the XY-TR01 support UART communication for microcontroller projects?

A: Absolutely. The module includes UART support and a Micro USB interface, making it easy to integrate into Arduino, ESP32, Raspberry Pi, or other microcontroller-based automation projects.

Q: How accurate is the XY-TR01 sensor?

A: The XY-TR01 offers high-precision detection with a control accuracy of 0.1°C for temperature and 0.1% RH for humidity. A built-in calibration function allows you to fine-tune temperature readings by up to ±10°C to account for any long-term sensor drift.
