In this guide, you'll learn how to connect a DHT22 sensor to your Raspberry Pi, run a python script in the Zoho IOT SDK to measure room temperature and humidity, and send this data to your Zoho IOT application using MQTT and visualize the data in the dashboard.
This setup allows you to monitor the room climate effectively, making it ideal for smart home automation or any project that requires real-time environmental data.
