Online Particulate Matter Sensor (with SSD1306 OLED)

thingiverse

This device employs an SSD1306 OLED screen in place of a traditional LCD. The code for this project is now publicly available, effective June 24th, 2019. Based on the PlanTower PMS5003 dust sensor, this device measures and displays real-time temperature, humidity levels, and PM2.5 values on its OLED screen. In addition to displaying measurements in real time, it also transmits data to ThingSpeak. To utilize this feature, a user must first create a free account with ThingSpeak, followed by the creation of one channel and three fields within that channel. Microcontroller Board: * NodeMCU v2 is utilized as the microcontroller board for this project.
