With integrated Wi-Fi and dual-mode Bluetooth, ESP32 is a series of low-cost, power-efficient systems on a chip microcontroller.
ESP32 can function as a fully standalone system or as a slave unit to a host MCU, which lessens the burden on the primary CPU application.
The ESP32 series was first introduced by Espressif Systems, a Shanghai-based Chinese company, and comes with the ESP32-D0WDQ6, ESP32-D0WD, ESP32-D2WD, and ESP32-S0WD.
With a wide range of peripherals that may be incorporated into various applications, the ESP32 is made to be flexible and scalable. As it comes with built-in support for Bluetooth and Wi-Fi networking, it is frequently employed in the Internet of Things (IoT) projects. It is also mainly used in wearable electronics, home automation, and other linked devices.
The ESP32 contains two independently powered and controllable CPU cores that can handle both 32-bit and 64-bit instructions. Additionally, it contains several GPIOs for attaching additional components as well as an integrated hall sensor, temperature sensor, and touch sensor. Due to its ability to carry out several instructions at once, the ESP32 is a good choice for activities that call for quick processing and responsiveness in real time.
Before we move further, know that ESP32 in IoT comes with many applications in many network devices and IoT projects.
