ESP32-S3 Camera Pan-Tilt Security Tracker: Build a Smart ESP32 Weather Station
I set out to build a pan-tilt security camera with an ESP32-S3 and ended up creating a fully-fledged ESP32 weather station while I was at it. The idea was simple: I wanted to keep an eye on the packages that couriers keep leaving in the rain, but also to know exactly how wet and miserable those packages were getting. Adding a cheap temperature and humidity sensor to the camera mount turned the project into something far more useful—a smart weather station that could see and feel the conditions in my backyard.
From ESP32 Weather Station to Home Security Monitor with HC-SR501 PIR Sensor
A few months ago I cobbled together a simple ESP32 weather station that dutifully reported temperature and humidity to my Home Assistant dashboard. It worked great until my cat decided the breadboard was a better bed than the couch. While the weather station slowly transitioned into a fur-covered sensor graveyard, I needed something else to do with the spare ESP32 Development Board Module I had lying around. That’s when the idea hit me: why not repurpose the same hardware I used for a weather station into a dead‑simple motion alert system?
Smart Weather Station ESP32: Control High-Voltage Appliances with a 2-Way Relay
Last winter my garage turned into a walk‑in freezer every night because I’d simply forget to flip the heater switch before bed. I wanted something that didn’t just display the temperature but actually did something with it—so I set out to build an ESP32 weather station that reads the room conditions and physically switches a high‑voltage appliance. The result is a small, Wi‑Fi‑connected brain that uses a 5V 2‑way relay module to control a space heater and an exhaust fan.
Build a Smart Weather Station with ESP32 and DHT11 OLED Display
Introduction I’ve always been slightly obsessed with knowing the exact temperature of my office. Not the outside weather — I can open a window for that — but the microclimate around my desk, where the Wi‑Fi router and the afternoon sun conspire to turn summer afternoons into a slow roast. A few months ago I threw together a bare DHT11 dangling from my ESP32, just spitting readings to the serial monitor.
ESP32 Weather Station Alert: DIY Touchless Alarm System with Infrared Obstacle Avoidance
Last winter, right after I had finally fine‑tuned my home‑brewed ESP32 weather station, our cat discovered the temperature sensor dangled from the windowsill and treated it as a feline punching bag. Within a week the outdoor humidity reading was permanently stuck at 99%—not because of a monsoon, but because the sensor had been batted onto the muddy ground one time too many. I needed a way to know when something (or someone) got within paw‑swiping range of my weather kit, without turning the project into a tripwire‑laden fortress.
