Temperature and Humidity monitoring with DHT22, ESP8266, and Blynk application!
Temperature and humidity monitoring are important in many applications, including agriculture, HVAC systems, and even in our homes. With the help of modern technology, monitoring these factors has become easier than ever. In this blog, we will learn how to use the DHT22 sensor, ESP8266 microcontroller, and Blynk application to monitor temperature and humidity levels in real-time. The DHT22 sensor is a popular choice for measuring temperature and humidity. It uses a capacitive humidity sensor and a thermistor to measure humidity and temperature, respectively. The sensor communicates with the ESP8266 microcontroller through a single-wire digital interface. The ESP8266 is a low-cost Wi-Fi microcontroller that is capable of connecting to the internet and transmitting data. REQUIREMENTS: To get started with this project, you will need the following components: DHT22 sensor ESP8266 microcontroller Breadboard Jumper wires USB cable Blynk applicationArduino IDE LIBRARIES TO IN...
