Arduino Outdoor Lighting Controller Kit - 4-Zone Relay, RTC Solar Time
Outdoor Lighting Scene Controller Kit - Arduino Uno, 4-Zone Relay, & Solar Time Automation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine your garden and pathway lights turning on automatically as dusk falls, and switching off at dawn, all synchronized to the actual solar time - not a fixed clock. This kit lets you build a four-zone outdoor lighting scene controller that reads ambient lux via a BH1750 sensor, calculates sunrise and sunset times with a DS3231 real-time clock, and triggers relays for four independent lighting circuits. With an OLED status display and tactile buttons for on-the-fly override, you'll create a robust, field-ready system used in villa exteriors, farmhouses, and smart campuses.
What You'll Build
An intelligent outdoor lighting system that controls four zones - porch lights, garden uplights, driveway accents, and facade washes - based on real-time daylight levels and solar time. The controller uses a sunrise offset to avoid nuisance triggering from clouds or artificial light. All zone statuses and live lux values are shown on the 0.96-inch OLED, and manual button overrides give you full control.
What You'll Learn
- Interfacing I2C sensors (BH1750 lux, DS3231 RTC) with Arduino and reading data reliably
- Writing embedded C code for real-time lighting decisions using light intensity thresholds and solar calendar calculations
- Using 4-channel relay modules to safely switch 12V outdoor lighting loads with flyback diode protection
- Integrating an OLED display to show live lux readings, RTC time, and zone status for field debugging

Who This Kit Is For
This advanced kit is tailor-made for B.Tech ECE and EEE final-year students prototyping solar-time outdoor automation, Smart India Hackathon teams building sustainable campus lighting, and research scholars at IITs, NITs, and VIT who need a repeatable hardware setup for embedded systems experiments. ATL Tinkering Labs with senior mentors will also find it a ready-to-assemble challenge in real-world sensor fusion.
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.

Can this controller operate outdoor lights directly from the relay module?
The 4-channel relay module can switch 12V circuits up to 10A per channel, enough for LED strips and small floodlights. For high-wattage mains loads, use external contactors; the relay acts as the control trigger.
How does the kit account for seasonal changes in sunrise time?
The DS3231 RTC maintains accurate calendar data year-round. The firmware calculates sunrise and sunset based on your location's latitude and lets you set a custom offset (in minutes) with the tactile buttons - so your lights adapt automatically every month.
Is soldering experience required?
Yes, this is an advanced kit. You will assemble the sensor breakout boards, resistors, capacitors, and connectors onto the PCB prototype boards using the included soldering iron and solder wire. Good soldering skills are essential.
BH1750 lux triggers sunrise and sunset relay switching of four lighting zones with RTC sunrise offset.
