Description

Build a Real, Working Smart Farm from Scratch - It’s your gateway to building a fully functional IoT farm. With the ESP32 at its core, you’ll assemble a charming wooden farmhouse, connect 8 sensors and 6 actuators, and bring it to life with code. Monitor real-time data, control devices remotely via WiFi, and see your creation respond to the environment.

Learn Two Ways to Code - Start with Scratch 3.0 — drag and drop colorful blocks to build logic visually. Then, when you’re ready, dive into Arduino IDE and write real C++ code. Every step comes with clear tutorials and sample code. Whether you’re a complete beginner or ready for a challenge, we’ve got you covered.

Rich Sensor & Actuator Set for Real Projects - This kit includes 8 sensors (soil moisture, water level, DHT11, PIR motion, light, rain, ultrasonic, button) and 6 actuators (water pump, servo, fan, LED, buzzer, LCD display). You’ll learn how sensors gather data, how actuators take action, and how to connect them all into a smart system.

Assembly & Coding Made Easy - Worried it might be too hard? Don’t be. We provide step-by-step online tutorials with video guidance and sample code for every single project. The kit comes unassembled (so you get the full building experience), and the code isn’t pre-burned (so you learn to upload it yourself). All you need is 6 AA batteries. No soldering.

Exquisite Models - You can paint them and customize them to create your very own masterpiece. This is both a craft project and a programming challenge—a truly immersive STEM experience that combines craftsmanship with coding.

Working Voltage: 5V; Battery Voltage: 9V; Maximum Output Current: ≤1.5A; Maximum Power Consumption: ≤10W; WiFi Working Principle: 2.4G; Bluetooth Protocol: v4.2 Full Standard; Dimension: 255*185*130mm±1%; Working Temperature: –10°C ~ +65°C.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $8 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for KEYESTUDIO products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
