Smart Sleep‑Based AC Control is an ESP32‑powered system that tracks how thermal comfort shifts through the night and adjusts the air conditioner automatically — so the room never has to guess, and the sleeper never has to wake up to fix it.
Sleepers wake up thermally uncomfortable, fragmenting rest and recovery cycles they're not even aware of losing.
The unit holds one temperature all night, indifferent to how the body's needs shift between 10pm and dawn.
Reaching for the remote means waking up fully — the fix costs the same sleep it's trying to protect.
Core body temperature drops at sleep onset and climbs again toward morning — a rhythm every static AC ignores. Scrub through a typical night below to see how the gap between room and body opens and closes.
Drag the dial to move through the sleep cycle and watch the system respond.
Remove manual temperature changes entirely by letting the system read and react on its own.
Keep the sleeper undisturbed by handling every thermal decision autonomously, all night.
Hold a consistently comfortable thermal window that supports deeper, more restorative sleep.
Continuously reads ambient and surface temperature to infer real‑time comfort levels.
Issues control signals to the AC based on live comfort analysis — no app, no remote.
Integrates with standard air conditioning systems already in the room — nothing to replace.
Sensors sample ambient and surface temperature continuously.
The ESP32 runs comfort logic against the sleep‑stage model.
Control signals reach the AC the moment a deviation is found.
The system holds the target band steady until the next shift.
Low‑power microcontroller handling all sensing and control logic.
Accurate ambient readings captured continuously across simulated sleep sessions.
An on‑device display shows current temperature and system status for monitoring and validation.
Fully automated — the sleeper never touches the AC overnight.
The system runs around the clock, adapting to shifting comfort needs in real time.
No new hardware investment — it works with the AC unit already in the room.
