SONOFF AM2301 Teplotní a vlhkostní senzor s 2,5mm audio konektorem

The 50cm cable gave me plenty of slack to tuck the sensor behind the fridge, and it reads the humidity changes in my dessert cabinet almost instantly. Set it up in under a minute, and the -40°C range is way more than I'll ever need.

The range on this thing is what sold me—tracking my pantry from -40°C to a scorching 80°C means it'll survive both my freezer and a hot summer shelf without a fuss. Plugged it in and the readings felt spot-on against my old thermometer, so I'm finally trusting the humidity numbers for my dried fruit

The 50cm cable is just enough to tuck the sensor behind my kitchen cabinet without weird angles, and the -40°C to 80°C range covers everything from my freezer to a warm proofing box. It's been spot-on against my old thermometer, so I'm finally trusting my sourdough temps.
