Smogly(formerly: Smogomierz) - simple and cheap PM 2.5 and PM10 sensor based on NodeMCU (ESP8266) or ESP32

Arduino Sketches that use ThingSpeak Web Services and API

Examples with connection to eduroam powered university networks around the world and then to IoT services or self-hosted websites..

IoT Geiger Counter with ESP32, OLED Display, Thingspeak Channel and MQTT

ESP8266 wifi enabled dual temperature probe device to monitor bbq meat / pit temperatures with wireless cloud data logging for remote monitoring and push alert notifications

In this project we have designed IoT Based Patient Health Monitoring System using ESP8266 & Arduino. The IoT platform used in this project is Ubidots (or ThingSpeak in old version).

Firmware for Sonoff Pow R2

ESP8266 projects

ESP8266 + DHT22 --> ThingSpeak

Displays SPO2 & heart-rate measurements from a MAX30102 sensor on an OLED display and logs the data in real-time to a Thingspeak channel

Wemos D1 mini WiFi meteostation

Connect the sonoff to the internet using the blynk app, you can also use a physical wall switch or add a DHT22 sensor

Espegi is an alternative firmware for ESP8266 based devices like iTead Sonoff with web UI, OTA updates, and Blynk support.
