Fine-dust monitoring station near Jeongwang 3-dong, Gyeonggi, South Korea. Channel updates once every minute with PM2.5 and PM10.0 readings from the Nova SDS011 Sensor. Also, provide real-time location tracking capabilities with the GY-NEO6MV2 GPS Module.

NodeMCU (programmed with Arduino sketch) & DHT22 (AM2302)

Portable fine-dust monitoring device. Air-pollution monitoring channel updates once per minute with PM2.5 and PM10.0 readings from the Nova PM (SDS011) Sensor. Also, provide real-time location tracking capabilities with the GY-NEO6MV2 GPS Module.

A weather forecaster (weathercaster) table clock powered by NodeMCU (ESP8266 & DHT22 Temperature Sensor).

A Smart Fridge. Unbreakable Kharkiv, Ukraine

7 days weekly average data for PM 2.5 and PM 10.0 based on the GONGGI channel data.

This project is mounted behind a solar panel which charges batteries that power the ESP8266 that hosts this project. The esp8266 in combination with a homemade fz0430 (voltage detector) measures the remaining battery and posts it here.

Temperatura y Humedad Exterior en VGG - Rosario - Santa Fe - Argentina -Modulo Esp8266

ESP8266 NodeMCU based clock, 60 NeoPixels ring display with DHT22, LDR, PIR and Audio sensors. Tracks CheerLights, updates no-IP and posts log data to ThingSpeak and Twitter.

This project for monitoring mangrove ecosystem based on physic and chemical parameters.

This is live electricity usage/generated data from my home. If the usage is zero it's because the solar panels are covering the load. :)

I am building many sensors using nodemcu and lua trying to connect everything together.. Have a look at my other thingspeak pages: https://thingspeak.com/channels/145827

Currently, this Nodemcu is used to measure the capacity from recycled 18650 notebook batteries. Values maybe empty before new battery start.
