Digital LCD Car Fridge Incubator Fish Tank Meter Gauge Thermometer with 1m cable

This is 125K RFID Tag. The RFID technology is used for sensing and identifying tagged people and objects for access control, automation, and a whole range of different applications.

Operating on a frequency of 125kHz, these tokens are all pre-programmed with unique ID numbers to communicate wirelessly with RFID Readers over distances of around 10cm or less. This means you can attach it to vehicles or items, keyrings or even pets’ collars to keep track of the location via an array of readers in the office, warehouse or home.

The MQ2 analog gas sensor is used in gas leak detection equipment. This sensor is suitable for detecting LPG, butane, propane, methane, alcohol, hydrogen, and smoke. It has high sensitivity and a fast response time; the sensitivity can be adjusted using a potentiometer.

5mm 5537 LDR is a 5mm light-dependent resistor with a « 5537 » model number, which is a photosensitive component that changes its electrical resistance based on the intensity of ambient light. Its resistance is high in darkness and decreases as light increases, making it useful for light-sensitive applications like automatic lighting systems, alarms, and light-level detection.

Stepper motor 28BY J-48 with Driver ULN2003

the ULN2003 stepper motor driver or in English stepper motor, unipolar (4 phases/ 5 wires ) allows you to easily plug the small motor 28BY J-48 5v gràce to the 5 pin male connector and connects easily to an arduino or other through a 4 pin connector for control signals and Gnd (ground/-). The power supply of ULN2003 is between 5 and 12V.

Arduino Nano has enough processing power to control many electronic components. It has several I/O pins, which allows to connect it to many components. , it is a compact and reduced version of Arduino uno maroc.

Arduino Nano has 14 digital inputs/types (6 of which can be used as PWM outputs), 8 analog inputs.

The ESP32-CAM is an ESP-WROOM-32 development board from AI Thinker, paired with a 2MP OV2640 color camera. The ESP32-CAM module also features an SD card reader that can be used to record images when an event is detected (e.g., presence or motion detector).
