Automatic Stevenson Screen Controller
Arduino Automatic Stevenson Screen Controller Kit – Motorised Louvers for Precision Environmental Monitoring
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a motorised Stevenson screen that opens its louvers at sunrise and closes them at sunset, protecting internal sensors while maintaining accurate ambient readings. Designed for meteorological enclosures, agricultural climate monitoring, and research-grade weather stations where hands-free, light-triggered control is essential. The system integrates a high-precision BH1750 lux sensor with a DS3231 real-time clock, so even cloudy periods don’t disrupt the daily schedule.
What You'll Build
A fully functional weather screen enclosure driven by four SG90 servos. The louvers respond to real-time light intensity, opening when ambient lux exceeds the sunrise threshold and closing after dusk. An on-board OLED constantly displays status, while a DHT22 inside the screen checks temperature and humidity—giving you confidence that your weather instruments are always in a properly ventilated, shaded environment.
What You'll Learn
- Interfacing a BH1750 lux sensor with Arduino to measure illuminance and trigger threshold-based actions
- Configuring a DS3231 RTC for reliable timestamps and scheduling of servo movements over days and weeks
- Controlling multiple SG90 servos to synchronise louver angle without mechanical binding or jitter
- Integrating a 0.96‑inch OLED and DHT22 into a live environmental dashboard for real‑time feedback

Who This Kit Is For
B.Tech ECE/EEE students tackling environmental automation capstone projects, Smart India Hackathon hardware track participants, and researchers at IIT/NIT/VIT developing automated weather stations will find this kit immediately applicable. CBSE Class 12 students with prior Arduino experience can use it for ATL‑mentored IoT explorations that demonstrate sensor fusion and actuator control in a real‑world context.
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.
What if I get stuck during the build?
Scan the QR code to launch the AI companion, which provides live debugging, wiring checks, and code walkthroughs tailored to this Stevenson screen design. You can also message us on WhatsApp for direct assistance.
Can this be used for a real meteorological station?
Absolutely. The louvered screen follows standard Stevenson enclosure guidelines, and the solar‑synchronised operation ensures internal sensors stay in a naturally shaded, ventilated state—identical to professional weather stations.
Is the kit solar‑powered or battery operated?
The included 9V battery snap powers the entire system for initial testing and short‑term deployment. For long‑term field use, you can add a solar panel and Li‑ion charger to the Arduino supply, and the AI companion covers the integration steps.
How do I calibrate the sunrise/sunset thresholds?
The build companion walks you through measuring local dawn and dusk lux levels and setting thresholds in the code. The DS3231 RTC allows seasonal correction when paired with date‑aware Arduino libraries.
Motorised louvers on a weather screen open at sunrise and close at sunset via BH1750 light sensing and RTC scheduling.
