Explore the Lua Modules directory on the NodeMCU documentation to identify the purpose of the 'mqtt' and 'sntp' modules, and determine which module provides support for the DHT11/DHT22 temperature and humidity sensors.
Navigate to the NodeMCU Documentation homepage. Locate and click on the 'Lua Modules directory' link (ID 128). On the 'Lua Modules' page, find the 'mqtt' module and describe its purpose. Find the 'sntp' module and describe its purpose. Search the page or the module list for a module that supports DHT11/DHT22 sensors and identify its name.
The agent successfully navigates to the 'Lua Modules directory' page. The purpose of the 'mqtt' module is identified as providing MQTT client functionality. The purpose of the 'sntp' module is identified as providing Simple Network Time Protocol (SNTP) client functionality. The agent identifies 'dht' as the module supporting DHT11/DHT22 temperature and humidity sensors.
