Last December Itead Studio updated their Home Automation product line with a new and different product. The main difference is that it doesn't have a relay and it's mainly sensors and no actuator (if we don't define a notifying LED as an actuator). The Sonoff SC is a sensor station that packs a DHT11 temperature and humidity sensor, a GM55 LDR, an electret microphone with an amplifier circuit and a Sharp GP2Y1010AU0F [Aliexpress] dust sensor in a fancy case that looks like it was originally meant for a speaker....

Have you ever forgotten your wet clothing inside the washer for a whole day? I have. Even for two days. They smell. You have to wash them again and you know you might end up forgetting about them again! Actually that is happening to me since me moved to an old house in a town north of Barcelona. Instead of having the washer in the kitchen, like we used to, now we have it in the cellar, in a place I don't normally pass by to notice the laundry is done....

Keeping on registering data from different sensors my next project has been the all-time favourite weather station. This time I wanted to build an 100% autonomous outdoor sensor. To achieve this goal I started playing with a LiPo battery and a solar panel. The Arduino Fio looked like the perfect out-of-the-box platform to be the center of the project. It's a ATmega328P (the same micro as the UNO), has a connection for a LiPo battery, a charge circuit based on the MAX1555 (with an USB connector) and a socket for an XBee radio module....
