Project Details
How It Works
How It WorksThe ESP32 reads data from the DHT22 (temperature/humidity) and BME280 (pressure) sensors periodically. It connects to a Wi-Fi network and uploads the sensor data to a cloud platform like ThingSpeak using HTTP requests. The cloud platform stores the data and provides a dashboard for real-time monitoring and historical analysis. The system can be powered by a battery for outdoor operation and uses Deep Sleep Mode to optimize power consumption.
