I decided to do some initial RSSI testing at various locations inside my house and outside in the backyard to see how much loss I was getting due to the structure of my house.  This is to get a baseline for further outdoor testing.   There are two components that determine the quality of the received radio signal, RSSI and SNR.  The LoRa Gateway measures these values for each transmission that it receives.   The Received Signal Strength Indication (RSSI) is the received sig ...

Ok, this is going to be very short, as this is just testing the DHT-11 module, as I really wanted a DHT-22. The DHT-11 is slower and less accurate that the DHT-22, which I have but have not found all of my goodies as of yet. I found a DHT-tester program as an example in the DHT-sensor-library-master.zip file. It was very simple to use. I only had to wire the three leads (ground, +5 vdc, data) to an Arduino mega and plug in my USB cable. It worked the first time, right out of the box. As you can ...
As we all experience with our projects - the Devil is in the details.  As I started to figure out how to mount all the components for the sensor in the case, I quickly realized that the case that I had chosen was too small.  One significant error that I has made was to use a AAA battery pack for sizing when my plan was to use a AA pack.   The case that I had intended to use is 100 x 60 x 25 mm and is shown on the left with MKR 1300 and the AAA battery pack.  And below that i ...

I have now make the I2C connections between the GridEye sensor and the Nano. The specific GridEye sensor that I purchased did not seem to have any accompanying documentation, although it was claimed there was some on the suppliers website but I could not find it. So, I decided that as it was a breakout board that most simple GridEye breakout boards would be pretty much the same so I used the Adafruit documentation and library.   There was one problem in that the GridEye is a 3.3V device bu ...

Lets say that my home has 2 bedrooms, 2.5 bathrooms, laundry, kitchen, Office, and a workroom(I like to tinker). So we are going to need six room controllers. So we will need several sensors in each of the rooms which in turn feed in the corresponding room controller. For starters, we will need to measure the temperature and humidity.  This can be handled by a DHT22 this is a serial device which simplifies integration. We need a way to talk to the user so we need some sort of display, and a ...

Ok, lets start what we mean by environmental control and what is it. Environmental control is what temperature, humidity, air quality.  Lets take theses one at a time so I don't loose you. Temperature:  This is the current temperature of you room or house. This can also be adjusted. Heating system can be Forced Air, Hot Water and Radiators, In Floor Radiant System (ether, electric or water).
