To display the º symbol, we use theCode Page 437font. For that, you need to set thecp437totrueas follows: display.cp437(true); Then, use thewrite()method to display your chosen character. The º symbol corresponds to character 167. display.write(167); A similar approach is used ...
Absolute humidity is the quality of water vapor in the wet air of unit volume (1 m3), for which the symbol is ρv. Because water vapor in humid air has the same volume as that of wet air, the absolute humidity is the density of water vapor in the wet air. (1.35)ρv=mvV=1vvwhe...
Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT31-D sensor has an excellent ±2% relative humidity and ±0.3°C accur
Step 1: SChematic The TFT LCD (3.5 inch, 320x480 pixel, ILI9488 LCD controller), is used for this instructable. The LCD is easily interfaced with Arduino SPI bus, and it needs minimum of four Digital IO lines. The ILI9488 LCD Controller is a 16.7M single-chip SoC driver for a-Si ...
