A self-contained round thermometer and hygrometer with its own LCD and its own button cell - not a module for an Arduino. Drop it into a 41 mm hole in an incubator lid, a filament dry box or a vivarium and it shows temperature and humidity with nothing wired to it. It reads -50 to +70 degrees C to about a degree and 10 to 99% RH to about 5%. It has no data pins, so a microcontroller cannot read it.
Key features
- Completely standalone - runs off one button cell
- -50 to +70 degrees C, plus or minus 1 degree C
- 10 to 99% RH, plus or minus 5% RH
- Panel-mounts in a 41 mm round cutout
- Humidity refreshes about every 10 seconds
- No data output - it cannot be read by an Arduino
