Is GSM module a microcontroller?

The circuit of interfacing GSM to AT89C51 microcontroller mainly consists of GSM modem and 8051 family microcontroller. GSM has RS232 interface for serial communication. In between the GSM module and the microcontroller MAX232 IC is connected. MAX232 IC is used for converting the logic levels.

How do I connect my fingerprint scanner to Arduino?

Enroll a New Fingerprint

  1. In the Arduino IDE, go to File > Examples > Adafruit Fingerprint Sensor Library > Enroll.
  2. Upload the code, and open the serial monitor at a baud rate of 9600.
  3. You should enter an ID for the fingerprint.
  4. Place your finger on the scanner and follow the instructions on the serial monitor.

What is the pin connection for fingerprint module?

Fingerprint sensor includes pins like DNC, VCC, TX, RX, and GND. These pins are connected through different colored connecting wires. Each color wire is used to indicate each pin of the sensor. The connection of the fingerprint sensor module to an Arduino board can be done like the following.

How does a fingerprint sensor module work?

The way an optical scanner works is by shining a bright light over your fingerprint and taking a digital photo. The light-sensitive microchip makes the digital image by looking at the ridges and valleys of the fingerprint, turning them into 1’s and 0’s, and creates the user’s own personal code.

What can I do with a GSM module?

A customised Global System for Mobile communication (GSM) module is designed for wireless radiation monitoring through Short Messaging Service (SMS). This module is able to receive serial data from radiation monitoring devices such as survey meter or area monitor and transmit the data as text SMS to a host server.
