A project log for ThermomUno

Turn a $20 Uno and LCD shield into a cheap thermometer!

As you can probably tell, I do indoor projects in winter, and it's coming up on winter in the South half of the world... %) Meanwhile, the Thermomuno has been in continuous operation since last year, and hasn't missed a beat. But watching it for that time has pointed out one other thing - the DHT-11 sensor is pretty shoddy - the humidity never shifted much either side of 40% during the whole year, while officially the RH moved between 20% and 80%. A slightly upmarket sensor might be on the cards, or maybe a range of them, in which case I'll keep this project updated.
