pm2.5 sensor driver for ESP32. Introduction. Both sds011.py and sds011_simpletest.py come from here, where I made some changes to make this code works for my ESP32. changes I made. when calling ...

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 ...

Ikea VINDRIKTNING PM2.5 air quality sensor functionality can be augmented with an ESP8266 WiFi board or module, and open-source firmware adding MQTT, or the popular Tasmosta firmware for more features ...

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 ...

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 ...

Recently, LoRa/LoRaWAN has been proposed as a promising LPWAN technology for Internet-of-Things (IoT) applications. For monitoring the long-term PM2.5 air quality on our campus, starting from February ...

This time we are using an SDS011 sensor with Arduino Nano to build Air quality Analyser. SDS011 sensor can calculate the concentrations of PM2.5 and PM10 particles in the air. Here the real-time PM2.5 ...

Sharp releases palm-sized PM2.5 sensor. Sharp aims to mass-produce 80,000 units of its new PM2.5 monitor every month, which it plans to achieve by outsourcing production to overseas partner factories.
