Arduino Hydreon RG-11 Optical Rain Sensor, with Solar Sensor - This is part of the TechEd Section. As mentioned previously, I was on the look out for a suitable Solar sensor to provide measurement of the strength of the Sunlight on our property. Now where the RG-11 is located is actually quite an ideal place for determining Solar light levels, as it has a clear Read more about Arduino Hydreon RG-11 Optical Rain Sensor, with Solar Sensor[…]- Arduino Hydreon RG-11 Optical Rain Sensor interfacing - This is part of the TechEd Section. My project of tying together various sensors to work out what is happening around the property is taking shape. I just took delivery of the Hydreon RG-11 Optical Rain Sensor a few days ago, cost $99 plus postage from Ocean Controls. A nifty little unit that makes use Read more about Arduino Hydreon RG-11 Optical Rain Sensor interfacing[…]
- Arduino Clones and DHT11 temperature/humidity sensor - This is part of the TechEd section. As previously mentioned, to diversify my techie skills (and its fun), I have a little side home DIY project on the go to achieve the following: Create a RS485 network, to allow me to easily connect together multiple Arduino’s over a distributed network. Gateway said RS485 network onto Read more about Arduino Clones and DHT11 temperature/humidity sensor[…]
- Arduino, RS485, mixed powers and multiple devices - This is part of the TechEd Section. As mentioned previously you need to be very careful when using multiple sources of power that are coupled by a common rail – nasty things can happen which will ruin your day (as well let all the critical magic smoke out). Luckily for me my power supplies are able Read more about Arduino, RS485, mixed powers and multiple devices[…]
- Arduino and multiple power sources – things to watch out for… - This is part of the TechEd section. As I mentioned previously , I had a need to double check that the 5v USB supply from my laptop was floating with respect to my lab power supply. I measured a no load difference on the 0v lines of around 120v – which raised the obvious concern Read more about Arduino and multiple power sources – things to watch out for…[…]
