This particular co-working space has a very poor air conditioning system - so poor that when I go in this space, I must go in as shown in the photo above. But now I have a little help from my MicroView - with MicroView Micro Meteo Station.
I use the MicroView to read and print on a little OLED screen the value of temperature and humidity. The project works with a 9 volts battery, or a USB port. You can connect this to your computer, or use it stand-alone. Now I put this in the co-working room. The chief doesn't ignore this silent demonstration.The materials are:Step 1: Connect the MicroView
I have made a board with connectors and 9V battery plug. You can connect all the components with a breadboard. Connect the DHT-11 to power supply (5V), and to pin number 2 of your Sparkfun MicroView. The DHT-11 needs a 4.7k resistor between the out pin and VCC pin. See the image.
After, you can install the DHT-11 library by https://github.com/adafruit/DHT-sensor-library
Test the sensor with the example test library. Do you see the temperature and the humidity? Right! Now upload the code!Step 2: Upload the Firmware
Connect your MicroView to your computer between the USB serial converter. Add the board to your Arduino IDE. To add the board, select Tools --> Boards --> Board Manager --> MicroView.
Open the txt file. Copy the file on your Arduino IDE, select the MicroView board, and upload the code.Step 3: See the Final Result
When you switch on the MicroView, you can see two values on screen. The first value is temp in C°, the second kind of value is humidity in %.
If you want to show the Fahrenheit temperature add this after
int mt = t-(t*0.13);
int mf = mt * 1.8 + 32;
widget -> setValue(mt);
widget -> setValue(mf);
