Smart Fursuit Cooling

Fursight Fan

Set-and-forget cooling for long con days.

A whisper-quiet blower with a TMP117 precision temperature sensor. Three automatic speeds with hysteresis — no oscillation, no fuss. Live telemetry on your phone over BLE.

Auto thermal curve

LOW · 40%below 26 °C
MID · 75%26 – 28 °C
HIGH · 100%above 28 °C

0.5 °C hysteresis between gears means the fan never chatters back and forth at the threshold — it commits.
