Delve into the crucial features, precision capabilities, and versatility of analog inputs, crucial for precise real-world data acquisition and control across diverse industries. NORVI’s tailored range of 0-10V and 4-20mA Analog Inputs presents customized solutions for industrial requirements.

What are Analog Inputs?

Analog inputs refer to the interfaces or ports on a device, such as a microcontroller, PLC (Programmable Logic Controller), or sensor, that are designed to accept analog signals. These inputs are crucial for acquiring and processing continuous real-world data that varies in amplitude or intensity over time.

Analog inputs typically allow the connection of sensors or devices that generate analog signals, such as temperature sensors, pressure transducers, potentiometers, strain gauges, and many others. These sensors produce signals that represent physical quantities like temperature, pressure, voltage, light intensity, etc., in analog form, which means they provide a continuous range of values.

Devices equipped with analog inputs use analog-to-digital converters (ADCs) to convert the incoming analog signals into digital form, which can be processed, analyzed, stored, or used by digital systems like microcontrollers or computers. The ADCs sample the analog signal at discrete intervals and assign digital values to represent the amplitude of the analog signal at those points in time.

Analog inputs are essential in various fields, especially in industrial automation, robotics, data acquisition systems, and scientific instrumentation, where precise measurement and control of analog data are critical for operations and analysis.

HMI Solution for IoT Projects

Human-Machine Interfaces (HMIs) play a vital role in connecting humans with machines, spanning a wide range of applications such as industrial process control, energy management, transportation, healthcare, consumer devices, smart homes, retail, defense, education, telecommunications, research, and public infrastructure management. These interfaces continually evolve to enhance user experiences and control across various sectors and technologies.

The NORVI HMI is an ESP32-based HMI featuring a 5-inch display with resistive touch capabilities, integrated digital inputs, and transistor outputs. The NORVI HMI distinguishes itself with its 5-inch LVGL 8 display, ESP32 S3 integration, built-in buzzer, and a diverse array of I/O options.
In this article, we will delve into the standout features of the NORVI HMI and compare it to the alternative display solutions on the market.

Serial driven displays, popular among HMIs, are well-regarded for their user-friendly interface creation and compatibility with microcontrollers like the ESP32. They communicate with microcontrollers through serial communication .

The key differentiation between these two HMI solutions lies in their microcontroller and processing methods. While the Serial HMI display relies on external microcontrollers with communication through serial channels, the ESP32-based NORVI HMI has an integrated ESP32 module, serving both UI functions and communication purposes. This integrated approach lends the NORVI HMI a cost-effective and higher performance edge compared to the Serial HMI display.

The NORVI HMI is based on the ESP32-S3 microcontroller, which has 45 physical GPIO pins. It utilizes 20 GPIO pins for the display and the majority of the remaining pins for various functions, including digital inputs, transistor outputs and communication.

NORVI HMI Pin Configuration

Features of NORVI HMI

  • 5-inch LCD Display with Resistive Touch: NORVI HMI offers a crystal-clear 5-inch LCD display with resistive touch technology, ensuring a user-friendly and interactive experience.
  • ESP32 S3 Integration: At its core, NORVI HMI harnesses the power of the ESP32 S3 module. This integration provides seamless communication capabilities and robust performance, making it a versatile choice for various applications.
  • Built-in Buzzer: NORVI HMI includes a built-in buzzer, allowing for auditory alerts, notifications, and user feedback, enhancing the user experience.
  • Ethernet (Optional) / Hardware: NORVI HMI gives you the option of Ethernet connectivity, making it possible to connect to networks and control devices remotely. The built-in hardware support ensures flexibility in connectivity.

ESP32 is a SoC where you can start your first IOT prototype with. There are many development boards available on the market. Its connectivity and speed make it possibly suitable for any IIOT application. In terms of programming, there are few IDEs and Languages you can use with ESP32.
Simply you can go with Arduino or ESP-IDF. I mostly use platform IO for programming ESP devices. Most of the arduino board compatible hardware is made compatible with ESP32 devices, and there are libraries to quickly get into the programming.
One of the hassles with ESP devices, is the boot pin. Once you have good hardware, the latest drivers and latest ESP-IDF version, putting it into boot mode automatically will not be a problem. When you are done testing your ideas, You need to implement it.
Then the problems with making ESP32 ready for Industrial Environments blocks you. You need proper enclosing, mounting and then good power supply, IO isolations, EMI Safety and reliable industrial grade electronics.
NORVI IIOT Industrial ESP32 is the most suited product on the market for any industrial IOT implementations. It has a combination of flexibility of ESP32 and Reliability of a PLC. It has featured your most familiar hardware, a 0.96 SSD1306 OLED Display and three buttons on top of the controller for any external commands.
That is what you need, a display to see what’s going on, and buttons to command that makes your troubleshooting quicker.
We know you are going to code the ESP32, so we focused our product on easy diagnosis and troubleshooting. We have been where you are, all the difficulties in making a custom board or using a development board in industrial application are solved in NORVI IIOT.
NORVI IIOT Industrial ESP32 is a direct competitor for most PLCs out-there.
All the Inputs and Relays in the NORVI IIOT is accessible with the same GPIO numbers as you program your development board. It doesn’t need any additional drivers or libraries. It has a built in USB port for programming.
