A 13.56 MHz RFID card, also known as a contactless RFID card or a proximity card, is a card that uses radio frequency identification technology to store and transmit data. It consists of an integrated circuit (IC) chip and an antenna embedded within a thin plastic card. The antenna allows the card to communicate with an RFID reader without the need for physical contact.
Voltage?Sensor is a precise low cost sensor for measuring voltage. It is based on principle of resistive voltage divider design. It can make the red terminal connector input voltage to 5 times smaller. Arduino analog input voltages up to 5V, the voltage detection module input voltage not greater than 5Vx5=25V (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).
DS3231 Module is a Bread Board friendly extremely precise I2C real time clock Module.?This module made using DS3231 RTC and AT24C32 EEPROM integrated with temperature compensated crystal oscillator. It also has a built in comparator which monitors the status of VCC to detect power failures and to automatically switch to backup power supply. AT24C32 provides 32,768 bits of serial EEPROM organized as 4096 words of 8 bits each. This gives you 32Kb of non-volatile memory for your projects. This module can be easily interfaced with Arduino Boards, Raspberry Pi and all Microcontrollers.
