🌑️ STC-3028 Digital Temperature & Humidity Controller (110–220V)

🧠 What is it?

The STC-3028 Temperature Humidity Controller is a plug-and-play controller used to automatically regulate temperature and humidity using external devices like heaters, coolers, humidifiers, and dehumidifiers.

πŸ‘‰ It’s widely used in environments where precise climate control is needed.

βš™οΈ How It Works

The controller uses:

  • A temperature sensor probe

  • A humidity sensor probe

Working logic:

  • You set desired temperature & humidity ranges

  • Device continuously measures current values

  • If values go beyond set limits:

    • It activates relays

    • Turns ON/OFF connected appliances

πŸ‘‰ Example:

  • Temp too low β†’ Heater ON

  • Humidity too high β†’ Dehumidifier ON

πŸ”Œ Input & Output

Power Supply:

  • 110–220V AC (direct mains input)

Outputs (via relays):

  • Temperature control socket

  • Humidity control socket

πŸ‘‰ Each output acts like an automatic switch.

πŸ”Œ Typical Socket Layout

  • Power input (plug to mains)

  • 2 output sockets:

    • 🌑️ Temperature device (heater/cooler)

    • πŸ’§ Humidity device (humidifier/dehumidifier)

πŸ“Š Key Features

  • Dual display (temperature + humidity)

  • Independent control for both parameters

  • High/Low setpoint configuration

  • Plug-and-play (no coding required)

  • Built-in relays for automation

πŸ“Š Specifications

  • Temperature range: -50Β°C to +99Β°C

  • Humidity range: 1% to 99% RH

  • Accuracy:

    • Temperature: Β±1Β°C

    • Humidity: Β±5% RH

  • Control outputs: Relay-based

  • Voltage: 110–220V AC

🧠 Control Modes

🌑️ Temperature Control

  • Set:

    • Target temperature

    • Heating or cooling mode

πŸ’§ Humidity Control

  • Set:

    • Target humidity

    • Humidifying or dehumidifying mode

πŸ”„ Working Example

Let’s say:

  • Temp set = 25Β°C

  • Humidity set = 60%

πŸ‘‰ System behavior:

  • Temp < 25Β°C β†’ Heater ON

  • Temp > 25Β°C β†’ Cooler ON

  • Humidity < 60% β†’ Humidifier ON

  • Humidity > 60% β†’ Dehumidifier ON

πŸš€ Applications

  • 🐣 Incubators

  • 🌱 Greenhouses

  • 🐟 Aquariums

  • 🏠 HVAC systems

  • πŸ„ Mushroom cultivation

  • πŸ§ͺ Laboratories

βœ… Advantages

  • No programming required

  • Controls both temperature & humidity

  • Works directly with AC appliances

  • Easy installation

  • Cost-effective automation

⚠️ Limitations

  • Limited precision compared to industrial controllers

  • Relay switching delay

  • Not suitable for very high-power industrial loads without external relays

  • Basic interface (no advanced logging or IoT)

πŸ” Safety Tips ⚠️

  • Works on high voltage (AC mains) β†’ handle carefully

  • Ensure proper earthing

  • Do not overload sockets

  • Use proper rated appliances

πŸ’‘ Real-Life Use Case

In a greenhouse:

  • Controller monitors environment

  • Automatically:

    • Turns ON heater at night

    • Activates humidifier during dry conditions
      πŸ‘‰ Maintains ideal plant growth conditions without manual effort
