Description

This example extends previous PM2.5 example to show the PM2.5 concentration on the LCD.
(Note: PMS3003/PMS5003 sensor requires 5V voltage)

Details

In this example, first rotate the screen by 90 degrees, and draw the static components such as the circles, the measuring scale, and the title text. After the concentration value is detected, it is printed inside the circle.

Components

1 × AmebaD [ AMB23 / AMB21 / AMB22 / BW16 ]
1 × ILI9341 TFT LCD with SPI interface
1 × PlanTower PMS3003 or PMS5003
