DHT22

JonixLUG-AQI V1 Air Quality Indicator Advanced dust sensor (PM2.5 and PM10) with fine tuning temperature and humidity algorithm.

DHT11 (DTH22) temperature+humidity sensor on STM8S.

IoT based Temperature Humidity Monitor is a project designed to measure ambient Temperature and Humidity. This project uses a DHT22 Sensor to monitor the ambient Temperature and Humidity of any location and report it to the server over the internet.

A distributed MQTT node written in Python

Arduino project to read temperature and humidity from a DHT22 sensor and record it in a local MySQL / MariaDB database over WiFi.

A ESP8266 microcontroller project to control an AC-powered fan based on humidity readings using Ardiuno CLI.
