Creating-Alert-Using-Ubidots+ESP32 and Vibration Sensor

In this project, we will create an email alert of machine vibration and temperature using the Ubidots-vibration sensor and ESP32.

Vibration is truly a to and fro movement — or oscillation — of machines and components in motorized gadgets. Vibration in the industrial system may be a symptom, or motive, of a hassle, or it can be associated with everyday operation. For instance, oscillating sanders and vibratory tumblers depend upon vibration to feature. Internal combustion engines and tools drive, then again, revel in a sure amount of unavoidable vibration. Vibration can imply a hassle and if left unchecked can cause harm or expedited deterioration. Vibration can be resulting from one or extra factors at any given time, the maximum not unusual being an imbalance, misalignment, put on, and looseness. This damage can be minimized by analyzing Temperature and Vibration Data on Ubidots using esp32 and NCD wireless vibration and temperature sensors.

Step 1: Hardware and Software Required

Hardware

  • ESP-32: The ESP32 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. This ESp32 IoT Module combines Wi-Fi, Bluetooth, and Bluetooth BLE for a variety of diverse applications. This module comes fully-equipped with 2 CPU cores that can be controlled and powered individually, and with an adjustable clock frequency of 80 MHz to 240 MHz. This ESP32 IoT WiFi BLE Module with Integrated USB is designed to fit in all ncd.io IoT products.
  • IoT Long Range Wireless Vibration And Temperature Sensor: IoT Long Range Wireless Vibration And Temperature Sensor are battery operated and wireless, meaning that current or communication wires need not be pulled to get it up and operating. It tracks the vibration information of your machine constantly and captures and operating hours at full resolution together with other temperature parameters. In this, we are using NCD’s Long Range IoT Industrial wireless vibration and temperature sensor, boasting up to a 2 Mile range using a wireless mesh networking architecture.
  • ZigBee Coordinator Long Range Wireless Mesh Modem with USB Interface

Software Used

  • Arduino IDE
  • Ubidots

Library Used

  • PubSubClient Library
  • Wire.h

Arduino Client for MQTT

This library provides a client for doing simple publish/subscribe messaging with a server that supports MQTT.

For more information about MQTT, visit mqtt.org.

Download

The latest version of the library can be downloaded from GitHub

Documentation

The library comes with a number of example sketches. See File > Examples > PubSubClient within the Arduino application. Full API Documentation.

Compatible Hardware

The library uses the Arduino Ethernet Client API for interacting with the underlying network hardware. This means it Just Works with a growing number of boards and shields, including:

  • Arduino Ethernet
  • Arduino Ethernet Shield
  • Arduino YUN– use the included YunClient in place of EthernetClient, and be sure to do a Bridge.begin() first Arduino WiFi Shield - if you want to send packets greater than 90 bytes with this shield, enable the MQTT_MAX_TRANSFER_SIZE option in PubSubClient.h.
  • Sparkfun WiFly Shield – when used with this library
  • Intel Galileo/Edison
  • ESP8266
  • ESP32The library cannot currently be used with hardware based on the ENC28J60 chip – such as the Nanode or the Nuelectronics Ethernet Shield. For those, there is an alternative library available.

Wire Library

The Wire library allows you to communicate with I2C devices, often also called "2 wire" or "TWI" (Two Wire Interface), can download from Wire.h

Basic Usage

Wire.begin()Begin using Wire in master mode, where you will initiate and control data transfers. This is the most common use when interfacing with most I2C peripheral chips. Wire.begin(address)Begin using Wire in slave mode, where you will respond at "address" when other I2C masters chips initiate communication.

Transmitting

Wire.beginTransmission(address)Start a new transmission to a device at "address". Master mode is used. Wire.write(data)Send data. In master mode, beginTransmission must be called first. Wire.endTransmission()In master mode, this ends the transmission and causes all buffered data to be sent.

Receiving

Wire.requestFrom(address, count)Read "count" bytes from a device at "address". Master mode is used. Wire.available()Returns the number of bytes available by calling receive. Wire.read()Receive 1 byte.

Step 2: Steps to Send Data to Labview Vibration and Temperature Platform Using IoT Long Range Wireless Vibration and Temperature Sensor and ZigBee Coordinator Long Range Wireless Mesh Modem With USB Interface:

Step 3: Uploading the Code to ESP32 Using Arduino IDE

  • Download and include the PubSubClient Library and Wire.h Library.
  • You must assign your unique Ubidots TOKEN, MQTTCLIENTNAME, SSID (WiFi Name) and Password of the available network.
  • Compile and upload the Ncd__vibration_and_temperature.ino code.
  • To verify the connectivity of the device and the data sent, open the serial monitor. If no response is seen, try unplugging your ESP32 and then plugging it again. Make sure the baud rate of the Serial monitor is set to the same one specified in your code 115200.

Step 4: Serial Monitor Output

Step 5: Making the Ubidots Work

  • Create the account on Ubidots.
  • Go to my profile and note down the token key which is a unique key for every account and paste it to your ESP32 code before uploading.
  • Add a new device to your Ubidot dashboard name ESP32.
  • Click on devices and select devices in Ubidots . Now you should see the published data in your Ubidots account, inside the device called "ESP32".
  • Inside the device create a new variable name sensor in which your temperature reading will be shown.
  • Now you can view the Temperature and other sensors data which was previously viewed in the serial monitor. This happened because the value of different sensor reading is passed as a string and store in a variable and publish to the variable inside device esp32. Go to data select dashboard and inside dashboard create different widgets and add a new widget to your dashboard screen.
  • Create a dashboard in Ubidots.

Step 6: Output

Step 7: Creating Events in Ubidots

  • Select Events (from the Data dropdown.
  • To create a new event, click the yellow plus icon in the upper right corner of the screen.

Types of Events Ubidots support already integrated events to allow you to send Events, Alerts, and Notifications to those who need to know when they need to know. Ubidots' prebuilt integrations include:

1. Email notifications

2. SMS notifications

3. Webhook events - learn more

4. Telegram notifications

5. Slack notifications - learn more

6. Voice call notifications - learn more

7. Back to normal notification - learn more

8. Geofence notifications - learn more

  • Then choose a device and associating variable that indicates the devices' "values."
  • Now select a threshold value for your event to trigger and compare it to device values and also select time to trigger your event.
  • Establish and configure which actions are to be executed and the message to the receiver: Send SMS, Email, Webhooks, Telegrams, Phone Calls, SLACK, and webhooks to those who need to know.
  • Configure the Event notice.
  • Determine the activity window the events may/may not be executed.
  • Confirm your Events.

Step 8: Output of Event in Your Mail
