  Smart House Monitoring System  ---------------------------------------------------------------------------      In previous labs, we had discussed about ESP32 microcontroller, different types of sensors, and Blynk application. Today, I am going to show you the product of combining and making use of the knowledges that I have learned throughout this semester which is to build a mini project.  --------------------------------------------------------------------------- Before proceeding, please ensure that you have  installed ESP32 properly in Arduino IDE software before proceeding. Click this link if you want to install Arduino IDE :  https://www.arduino.cc/en/software --------------------------------------------------------------------------- Besides that, please ensure you have installed and setup Blynk application before proceeding. (Take note that I am using the  OLD VERSION  of Blynk app in this lab.) Click this link if you want to ...

It is the advance version of ESP8266 and is loaded with lots of new features.  Below are the specifications of ESP32 :  - ESP32 is dual core. (It has 2 processors.) - It has built-in Wi-Fi and bluetooth. - It runs 32 bits programs. - The clock frequency can go up to 240M Hz.  - It has a 512 kB RAM. - This particular board has 30pins. (There is also a new version which has 36pins.)
