On top of the waveform, as well as the numbers on the main screen, you can notice we have like transparent objects, called “Hotstops” in the Nextion editor, and they are act as buttons. The hours and the Y-axis values also get their values from the Arduino. Now if we try to connect everything together, we will get quite a mess because of the many connections. See also: The 8 Best Arduino Starter Kits The whole device is powered with 5V through a Mini USB connector. We are also using a Real Time Clock module for keeping track of the time when storing the sensors values, and it uses the I2C communication. The two transistors are used for activating the sensors heaters. For reading the VOC and the Ozone sensors we use analog inputs of the Arduino, while the DHT22 temperature and humidity sensor uses a digital pin for that purpose. The CO2 sensor and the Nextion display also use serial communication. It works at 5V, but the receive RX logic level works at 3.3v, so therefore we need a voltage divider for it. The PM2.5 sensor communicates with the Arduino through a serial interface. As an Amazon Associate I earn from qualifying purchases.Ĭorrect resistors values: R1 = 1K, R2 = 2K, R6=100K or 1M, R7=1K

Heat-resisting property, chemistry resisting, impact endurance, peel-off resisting must be good. Water absorptivity has to be reduced, high water absorptivity will certainly influence DK as well as DF when in the damp atmosphere.ĥ. The thermal expansivity ought to coincide with copper aluminum foil as long as feasible, due to the fact that the distinction will certainly result in copper aluminum foil divided in the modifications of cool and also warm.Ĥ. DF ought to be little, which mostly influences the top quality of signal transmission, the smaller sized DF might make smaller sized signal waste as necessary.ģ. DK needs to be tiny as well as steady sufficient, typically the smaller sized the much better, high DK might cause signify transmission hold-up.Ģ.
