• Aquarium temperature control

• Refrigerators & freezers

• Water heater automation

• Electronics lab experiments

• Smart farming & greenhouse projects

• DIY Arduino & automation learning (relay-based)

Why Students & Engineers Choose W3001

• Simple 2-button programming

• No microcontroller required

• Budget-friendly for students

• Works directly with 220V AC loads

• Easy to integrate with real-world systems

• Widely supported with tutorials in Bangla & English

How It Works:

The W3001 reads temperature using its NTC sensor.
You set a target temperature.
When the temperature crosses the set value, the relay turns ON or OFF automatically, controlling heaters, fans, or coolers.

Perfect for learning control logic without complex coding.
