It’s been a while since I last time I wrote about some awesome hack… So here we go…
The device above monitors temperature, humidity and pressure (Too bad it wouldn’t monitor dust… Or it could’ve been so useful here in Kuwait :P)…
The screen shows the extreme temperature values for the last 24 hours and can be switched to the other values (humidity and pressure)…
It updates every minute, and last months on AA batteries…
