How to optimize the performance of data center with Arduino PLC, Raspberry PLC or ESP32 PLC
Free preview
In this video we want to show you the importance of monitoring your data center installation.
There are several key indicators (KPIs) that must be analyzed and acted on to obtain the best performance and it can be done with a good installation of sensors and the use of industrial Arduino PLC, Raspberry PLC or ESP32 PLC.

You need to monitorize at plant level, cabinet or server rack level and also each one of the units.

The monitoring of critical elements such as:

- temperature
- humidity
- space available
- tension points or hot spots
- energy consumption
are important to know if your installation is efficient and where it can be improved.

SUMMARY of the post:
What is Arduino Serial Communication and How to use it.
There are different types of Serial Communications. When you use an Arduino board in a project, you can choose the standard Serial pins such as Rx, Tx, from the UART inside the Arduino board, so it is called Serial TTL. In that case, you will use the Hardwareserial.h library but there are some additional pins that can work as an Rx or Tx. For example, the SPI communication pins can work as a MISO, MOSI and Select (SC), but they are also pins that can work as a digital input or digital output, or if you need you can use those pins as Rx, Tx using the library softwareserial.h.

Serial communications allow you to connect two different devices sending and receiving data between them.

The Serial TTL port can be transformed as required in the Industry as a RS232 and as a RS485. When RS232 is used, the functionality is quite similar to working as Serial TTL but, if you work with RS485, you can configure a network using a Master device that is capable of connecting to Slave devices. So the number of devices has been increased from 2 to 32 devices (nodes). And the maximum distance between them can be up to 1220m if the wiring is well done and EMC compliant and electrical noise is avoided.

To sum up, if you are using the UART serial port from the Arduino or from the Arduino based PLC for Industrial projects, the use of other pins working as a Serial TTL can help you with the successful development of your project. So, that additional serial port must be programmed using softwareserial.h library.

If the hardwareserial library can not be used because you need to use a communication protocol that requires the use of a physical UART instead of a virtual serial port, then, you could convert the RS232 or RS485 standard from the device to a Serial TTL. (This example will be shown in another post).

In this post, we explain the advantage of the SoftwareSerial library to simulate a serial port through Software (virtual serial TTL) using the Arduino IDE.
