About 40% of our energy bill is spent on electricity and 60% on gas, which we use to heat our house and for hot water. Although we do have a relatively recent HR central heating installation, I don’t think that it has been tweaked for efficiency Everyone downloads psychics. After reading this post on optimising the yield of the central heating installation, I decided it would be worthwhile to try and acquire some data 하얀고양이 데이터.
Power is provided by connecting a rechargeable 18650 LiPo battery to VCC on the programming header of the Arduino 엔젤 전설. This battery provides nominally 3.7V, which in my experience is close enough for the board to work fine. The whole module is mounted in a battery holder for two 18650 batteries 모의고사 시험지 다운로드.
Every 66 seconds a temperature reading of both sensors is performed and transmitted it to the central relay module. The central module forwards it to ThingSpeak to acquire a long-term log of the behaviour of our central heating system 창세기전 게임.
You can find the sketch for the Arduino here.
