Reyax rylr890/rylr896 LoRa based Multiple Sensors monitoring using Arduino

Arduino Projects 2020

Reyax Lora based Multiple Sensors Monitoring- This is my third tutorial on the Reyax rylr890/rylr896 15km 915Mhz transceiver module. In this tutorial, you will learn how to make Multiple Sensors Monitoring system using Reyax rylr890 based Lora Module and Arduino. This is an advanced level project and explains how to split the entire string message and store the different parameters in different variables.

With the help of this project you can monitor Multiple Sensors within 15km range. In this project, I have used three variable resistors as the sensors, which of course you can replace with any other sensors you want. As the Sensors values are stored in different variables, now you can use if conditions to monitor each sensor individually and then you can control some relays or you can send notification messages, etc.

Diy Internet of Things Fridge, Smart IoT Refrigerator “Nodemcu ESP8266, DS18b20, Blynk”

Arduino Projects 2020
Diy Internet of Things Fridge, Smart IoT Refrigerator “Nodemcu ESP8266, DS18b20, Blynk”

The internet of things based Fridge or smart IoT Refrigerators are becoming very popular, because with the help of a smart IoT refrigerator you can check the temperature, food items expiry date, Door opening and closing status from anywhere around the world using the Wifi technology. In this episode you will learn how to convert any Fridge or Refrigerator into a smart internet of things based Fridge or Refrigerator using a Push Button or a limit Switch, Nodemcu ESP8266 Wifi Module, a variable resistor, DS18b20 one wire waterproof digital temperature sensor capable of measuring the temperature from -55C to 125 Centigrade, and a cell phone application designed in Blynk.

The Values are updated every second, the notification messages are sent to the owner each time the temperature increase above or decreases below a certain predefined value which can be adjusted using a variable resistor. Any value between -40 and +40 can be selected; this limit is specified in the programming which can be changed as per the requirement…..

A pushbutton or a limit switch can be used with the Fridge or a refrigerator to check if the Fridge door is opened or closed. If the door remains open for 3 minutes a notification message is sent to the owner, the three minutes delay can be increased or decreased as per the requirement…

The notification messages are sent even if the application is running in the background… if in case due to some problem the Wifi connection is disconnected a notification message is sent to the owner or supervisor. This project can be easily modified by adding more sensors and some relays for controlling the Fridge or Refrigerator.

Arduino 10.1” HMI intelligent TFT LCD 220 Vac Load Controller Panel “Stone Technologies”

Arduino Projects 2020

In this project, you will learn how to control electrical loads using 10.1” HMI TFT LCD Display Module and Arduino Uno. The control commands are sent serially from the HMI Touchscreen display Module through the max232 board to the Arduino. The Arduino then Turn ON and Turn OFF the desired load depending on the command. Using the same button you can Turn ON and Turn OFF the load, the buttons used on the HMI GUI works as the Toggle switches. For the demonstration purposes I have connected 220Vac light bulbs which you can replace with other AC or DC loads. Be very careful while working on the 220Vac as it can be really dangerous, wear protective gloves. Make this project on your own risk.

Arduino Projects 2020

Arduino ISD1820 Voice Recorder & Playback Module- In this tutorial you will learn how to interface the ISD1820 Voice Recorder and Playback Module with Arduino and play different recorded messages using different Sensors. In this tutorial we will cover both the manual and automatic control of the ISD1820 Module.

There are situations when you need to play a specific recorded voice message depending on the situation. Like for example, in case if someone end up in a Car accident, when a sensor detects a strong hit a pre-recorded voice message is played endlessly.

The ISD1820 Voice Recorder and Playback Module can also be used in Security based projects. When an intruder is detected a voice message is played endlessly.

The ISD1820 module can be used in offices where you need to play different voice messages, for example when someone opens the door; a welcome message is played only one time.

If it’s a break time you can record a new message, now this time if someone opens the door the break time voice message will be played. You can record different messages depending on the situation.

Diy Digital World Clock using Nodemcu ESP8266 and HMI TFT LCD

Arduino Projects 2020

Diy Digital World Clock using Nodemcu ESP8266 and HMI TFT LCD- In this tutorial, you will learn how to make a World Clock using a 10.1 inch HMI TFT LCD display module by the Stone Technologies and a Nodemcu ESP8266 Wifi Module by the ESPRESSIF systems. This is the smartest World clock; you don’t have to enter the hours, minutes, and seconds manually and there is also no need to use the RTC “Real Time Clock” Module.

All you need simply select a time zone on your cell phone application designed in Blynk, wait for a minute and the time will be updated.

If due to some issues, the Wifi is disconnected the World Clock won’t stop working, the minutes and seconds are incremented automatically and will continue to work. When the wifi connection becomes active the World clock is synchronized again with the server time.

This world clock is based on the 24 hours time format due to which we can easily know if it’s the day time or night time. This is my 5th tutorial on the 10.1 inch HMI intelligent TFT LCD module which is entirely based on my previous 4 tutorials.
