Build a Smart Air Conditioner Temperature Controller with This ESP8266 Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Your air conditioner’s built-in thermostat is often inaccurate, and its timer can’t respond to real room conditions. With this kit, you build a standalone gadget that reads temperature and humidity via a precision DHT22 sensor, then fires the exact infrared commands your AC expects — no original remote, no cloud, just local intelligence. It’s home automation you can hold in your hand.

What You'll Build

You’ll assemble a compact controller that clips onto any 400-point breadboard and connects to your AC unit through learned IR codes. The ESP8266 continuously monitors the room, comparing it to your target setpoint. When temperature drifts, the device sends the right IR signal — just as if you’d pressed the remote. It works with split, window, and portable air conditioners from nearly every brand.

What You'll Learn

• Reading high-accuracy DHT22 temperature and humidity data with ESP8266
• Capturing and replicating IR remote codes using the TSOP1738 receiver
• Driving IR LEDs through BC547 transistor switching circuits
• Designing a closed-loop temperature feedback system in Arduino IDE

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Engineered for B.Tech ECE and EEE students building IoT home automation prototypes, this kit plugs straight into curricula and hackathon requirements. CBSE Class 11-12 science students get a tangible embedded systems project, while participants in the Smart India Hackathon can quickly deploy a ready-to-learn IR module. ATL Tinkering Lab instructors will appreciate the guided, solder-free build that teaches sensor-actuator fundamentals.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
