AI-QR Code Scanner

A QR Code is a type of two-dimensional matrix barcode invented in 1994 by Masahiro Hara of Japanese company Denso Wave for labelling automobile parts. It features black squares on a white background with fiducial markers, readable by imaging devices like cameras, and processed using Reed–Solomon error correction until the image can be appropriately interpreted. The required data is then extracted from patterns that are present in both the horizontal and the vertical components of the QR image.

Whereas a barcode is a machine-readable optical image that contains information specific to the labeled item, the QR code contains the data for a locator, an identifier, and web-tracking. To store data efficiently, QR codes use four standardized modes of encoding: numeric, alphanumeric, byte or binary, and kanji.

AI Motion Sensing

AI Motion Sensing scan text for clues that hint at AI involvement. They analyze sentence structure, predictability, and writing patterns using machine learning models trained on both human-written and AI-generated text. Some even go a step further by checking metadata or comparing content to known AI outputs.

Sets the motion detection sensitivity, the larger the setting value, the more sensitive the detection of motion, the range is 0-100. If you do not set the sensitivity when using motion detection, the default is 50.

LITE-ON Technology – Ambient Light Sensor

The LTR-303ALS-01 is a low voltage I2C digital light sensor [ALS] in a low cost miniature chipled lead-free surface mount package. This sensor converts light intensity to a digital output signal capable of direct I2C interface. It provides a linear response over a wide dynamic range from 0.01 lux to 64k lux and is well suited to applications under high ambient brightness.

Gravity: Analog Ambient Light Sensor

This Gravity: Analog ambient light sensor can assist you in detecting light density and provide an analog voltage signal to the controller as feedback. Additionally, you have the ability to trigger other components within your project by setting voltage thresholds.

    MicroSD Card Module

    There are different microSD card modules compatible with the ESP32. We’re using the microSD card module it communicates using SPI communication protocol. You can use any other microSD card module with an SPI interface. This microSD card module is also compatible with other microcontrollers like the Arduino boards. To learn how to use the microSD card module with the Arduino. You can connect it to the ESP32 using the default SPI pins.

    Global Positioning System (GPS)

    The Global Positioning System (GPS) is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.

    GPS Receiver – GP-20U7

    The GP-20U7 is a compact GPS receiver with a built-in high performances All-In-One GPS chipset. The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability.

    Adafruit DS3231 Precision RTC FeatherWing

    This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator to any Feather main board. This RTC is the most precise you can get in a small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that’s all well and good, but those crystals have slight drift, particularly when the temperature changes (the temperature changes the oscillation frequency very very very slightly but it does add up!) This RTC is in a beefy package because the crystal is inside the chip! And right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule. With a CR1220 12mm coin cell plugged into the top of the FeatherWing, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time.

    EEPROM

    EEPROM (Electrically Erasable Programmable Read-only Memory) is a type of non-volatile memory. EEPROM is a type of non-volatile ROM that enables individual bytes of data to be erased and reprogrammed. That is why EEPROM chips are known as byte erasable chips. EEPROM is usually used to store small amounts of data in computing and other electronic devices. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.

    The microcontroller on the Arduino boards have 512 bytes of EEPROM: memory whose values are kept when the board is turned off. Functions in the EEPROM class are automatically included with the platform for your board, meaning you do not need to install any external libraries. The supported microcontrollers on the various Arduino have different amounts of EEPROM: 1024 bytes on the ATmega328P, 512 bytes on the ATmega168 and ATmega8, 4 KB (4096 bytes) on the ATmega1280 and ATmega2560. The Arduino boards have an emulated EEPROM space of 1024 bytes. The EEPROM library on ESP32 provides a reliable way to store data persistently, so that it remains accessible even when the power supply is disconnected. Unlike RAM, the data we save with the EEPROM library does not get lost when power is cut. This feature makes it an ideal choice for retaining configurations, settings, and other important data in embedded devices like the ESP32.
