In this tutorial, we'll guide you through building a wireless temperature and humidity sensor using the ESP32 microcontroller with ESP-NOW technology. This project is ideal for those interested in creating low-power, real-time environmental monitoring solutions without the need for Wi-Fi or Bluetooth connections.
We'll be using a DHT11 or DHT22 sensor to measure temperature and humidity, paired with the ESP32's efficient ESP-NOW communication protocol to transmit data wirelessly over long distances. The tutorial will walk you through setting up the hardware, writing the code using the Arduino IDE, and establishing a wireless link between multiple sensors and a central node. By the end of this project, you'll have a robust, battery-efficient sensor network that can be used for smart home automation or remote environmental monitoring.
