A simple air quality monitoring system that uses an ESP32 microcontroller and a PM2.5 sensor (such as PMS5003) to measure air pollution levels. The measured data is displayed on an LCD1602 display via ...

SDS011 Sensor, DHT11, and MQ-7 sensor are powered with +5V while the OLED Display module is powered with 3.3V. The transmitter and Receiver pins of SDS011 are connected to GPIO16 & 17 of ESP32. The ...

PM2.5 Sensor: e.g., PMS5003. CO2 Sensor: e.g., MH-Z19B. Wi-Fi Module: Often built into modern microcontrollers like ESP32. Power Supply: Ensure it's compatible with ...

Once you’ve connected your ESP32 to an IDE on your PC, all you have to do is write a function that can read these values from the microcontroller and display them on the output section of your IDE.

Polverine is a mikroBUS-compatible environmental sensing platform featuring a BMV080 PM2.5 sensor and a BME690 gas sensor, plus an Espressif ESP32-S3-MINI-1 module to add Wi-Fi 4 and Bluetooth 5 ...
