STC-3028 Temperature & Humidity Controller – Precise Dual-Display Hygrostat & Thermostat

The STC-3028 is a robust, user-friendly thermostat/hygrometer controller designed to maintain and regulate both temperature and humidity in a wide range of environments. Equipped with a dual-display for real-time temperature (°C/°F) and humidity (%) readings, plus a waterproof SHT20 sensor, it enables accurate monitoring and automatic control through a 10 A dual relay — perfect for climate-sensitive systems such as incubators, greenhouses, terrariums, cold rooms, fermentation chambers, and humidity-controlled storage.

🔧 Key Features & Technical Specifications

• Dual Display: Shows both temperature and humidity simultaneously — no need for separate meters.

• Built-in Waterproof Sensor (SHT20): Reliable, water-resistant sensor — suitable even in high-humidity, misty or wet environments.

• Wide Power Input: Supports 110–240 V AC — versatile for global use.

• Relay Output: 10 A relay capable of controlling heaters, humidifiers, dehumidifiers, fans, or cooling units.

• Temperature Range & Humidity Range: Typical controller supports wide temp range (e.g. –10 °C to +99 °C) and humidity range (e.g. 20% to 99% RH) — exact limits vary by version.

• Alarm & Protection: Configurable upper/lower thresholds for temperature/humidity — triggers relay or alarm for safe automatic control.

• Easy Setup & Configuration: Simple buttons to set target values, hysteresis, sensor calibration, and control mode (heat/humidity or cool/dehumidify).

• Panel Mount Design: Compact size for mounting on incubators, grow-boxes, control panels, or enclosures.

🛠 Applications & Use Cases

• Incubators & Hatcheries — Maintain optimal temperature and humidity for eggs, reptiles, or amphibians.

• Greenhouses & Plant Nurseries — Control climate: automated ventilation, humidifier, or heater to support plant growth.

• Reptile Terrariums & Pet Enclosures — Keep stable living conditions (heat + humidity) for reptiles, amphibians, or exotic pets.

• Fermentation & Curing Chambers — Maintain stable environment for fermentation, cheese curing, or mushroom growth.

• HVAC & Climate Control Systems — Use as central climate controller in small rooms, storage units, or cold rooms.

• DIY Home Automation & Smart Agriculture Projects — Ideal for combining with IoT modules like Arduino, NodeMcu, or Raspberry Pi for advanced automation.

⚠ Precautions & Best Practices

• Ensure relay load does not exceed 10 A rating — for heavy loads, consider external relay or contactor.

• Place sensor where it can measure ambient air — avoid direct contact with heaters, humidifiers, or water sprays.

• For humid environments, ensure wiring and controller are protected from condensation.

• Use stable AC supply (110–240 V) and proper grounding for safety.

• Regularly calibrate sensor if used for critical humidity control (e.g. incubation or horticulture).
