20141214· A second Arduino connected to a data logging shield, a DS18B20 temperature sensor and another CO2 sensor was placed on the middle of the DIY incubator after it had been running for at least a day. The door was closed and the incubator was allowed to stabilize for three hours. At this point the Arduino was switched on and began logging temperature and CO2 every 5 seconds. After 10 …
These two jumper cables are important as they will allow both the EZOCO2 sensor and the Arduino Uno board to communicate with each other. (image number 2 above) Next, place the red jumper cable into the 5V pin. And finally, place the black jumper cable into any of the 2 GND or ground pins near the 5V pin. These two jumper cables will now supply power and a ground line from the Arduino Uno to ...
