Complete ESP32 tutorials starting from basics to advances level. ESP32 is a famous development board for the internet of things applications. Although, other IoT development boards are also available in the market. But this board gains popularity among embedded developers and hobbyists in a short time. Because of its on-board many features such as Bluetooth, BLE, WiFi, Crypto-Engine and many others.
In this article, we will learn how to interface the LM35 temperature sensor with ESP32. LM35 is a very popular temperature sensor in academia, and many students want to integrate it into their ESP32 projects. But due to the issue of ESP32 ADC incompatibility, we cannot interface LM35 directly with ESP32. In this guide, we … Read more
