The female safety device inside a purse, handbag, or school bag can be operated using a small wireless transmitter. All the electronics are powered up using the rechargeable Lipo Battery. All these modules are interfaced with the Arduino Nano.
This ESP32 Camera based face recognition door lock control system depends on my previous two tutorials.Īny Purse can be converted into a smart purse with the women safety device provided with a wireless receiver, GSM module, and a GPS Module. For the Authorized person, the onboard white LED is turned ON and also the electronic lock is opened.

In this tutorial, you will learn how to make Face Recognition based Door Lock Control system using ESP32 Camera Module and a 12V electronic lock. Video tutorial ESP32 Cam face recognition Door Lock The Heart rate or Pulse rate or Heart beat is measured in BPM which is also known as the beats per minute while the Blood Oxygen Concentration is measured in percentage.

You will learn a lot of new things and you can easily modify the code to make other cool projects. In this tutorial, you will learn how to make a long-range Wireless industrial Temperature monitoring system using Arduino Nano, NRF24L01 Transceiver modules, Industrial temperature sensor capable of measuring the temperature up to 1000 Centigrade, and an I2C supported Oled display Module. Video Tutorial Long Range Wireless Industrial Temperature Monitoring System In this article, I explained what are primary and secondary batteries? The charging and discharging chemical reactions, the basic working of a Battery Cell, and so on. Read my article on the Basic Working principle of the Lead Acid Batteries. I will also explain in detail how to internally connect the positive and GND plates in series? In the end, I will also explain how to prepare electrolyte for the battery using Sulfuric Acid, and how to test the specific gravity of the Lead Acid Battery electrolyte using a Hydrometer. I will also explain what are the necessary tools for making the Lead Acid Battery and how to use them? I will also explain how to make the Battery internal and external terminals using metal dies. In this tutorial, you will learn how to make and repair any type of Lead Acid Battery using new and old positive and GND plates. So, if you want to learn how to use the pH sensor kit from the DFrobot then I highly recommend read my previous articles. I have also used the same Diymore pH Sensor with the ESP32 and built an IoT pH Meter. I also used the DFrobot pH sensor kit for measuring the water quality using the Arduino board and I also used the pH sensor kit from the DFrobot in an IoT based water quality monitoring system using the NodeMCU ESP8266 WiFi module. PH Meter Arduino– This is the analog pH sensor kit from the DIY MORE which is a bit different from the one developed by the DFrobot which I have already used in some of my previous projects explaining what is a pH sensor, it’s working, Calibration, and how to use a pH sensor to find the pH value of different liquids. Long Range Wireless Battery Voltage Monitoring– In this tutorial, you will learn how to make a Long Range Wireless Battery Voltage Monitoring system using Arduino, HC05/HC06 Bluetooth Module, NRF24L01 Transceiver Modules, 0-25v Voltage Sensor, and Android Cell Phone Application. Long Range Wireless 12V Battery Voltage Monitoring System: Long Range Wireless Battery Voltage Monitoring using NRF24L01, Bluetooth, Arduino, & Android App Different sensors are used with Arduino, ESP32, & ESP8266. These are mixed projects based on Arduino Uno, Arduino Nano, Nodemcu ESP8266, and ESP32 WiFi + Bluetooth Module. Today, I am going to share with you my top 20 projects from the year 2020.
