The ESP01, as a low-cost, low-power WiFi module, provides a convenient solution for implementing temperature and humidity monitoring. This article details how to use the ESP01 board for temperature and humidity monitoring development, including hardware connections, code implementation, and functional analysis.</p> <h2 id="hardware-preparation">Hardware Preparation</h2> <ul> <li><strong>ESP01 Board</strong>: Core control module, responsible for data collection and network communication. <img src="/posts/iot/images/esp01-dht11-01.jpg" alt=""></li> <li><strong>DHT Temperature and Humidity Sensor</strong>: Used to measure ambient temperature and humidity. <img src="/posts/iot/images/esp01-dht11-02.jpg" alt=""></li> <li><strong>Dupont Wires</strong>: Used to connect the ESP01 and DHT sensor.</li> </ul> <p>Connect the DHT sensor&rsquo;s VCC pin to the ESP01&rsquo;s 3.3V pin, the GND pin to GND, and the data pin to the designated pin on the ESP01 (defined as <code>DHTPIN</code> in the code).</p>
