GPS stands for Global Positioning System, a satellite-based navigation technology that provides positional, navigational, and timing data. By receiving signals from multiple satellites, a GPS module can calculate the user’s 3-dimensional position—specifically, latitude, longitude, and altitude. This makes it essential for applications involving tracking, mapping, and location-based services.
Wi-Fi is an acronym for Wireless Fidelity, a technology that enables wireless connectivity for internet-based applications, such as those in the Internet of Things (IoT) ecosystem. It allows devices to communicate and exchange data over local networks or the internet without physical connections.
BLE, short for Bluetooth Low Energy, also known as Bluetooth 4.0, is a wireless communication technology designed for low power consumption while maintaining reliable data transmission. Unlike Classic Bluetooth, BLE is optimized for applications that require long battery life, making it ideal for wearables, sensors, and battery-powered IoT devices.
Bluetooth Module enables a microcontroller to communicate wirelessly with other Bluetooth-enabled devices using Bluetooth communication. It interfaces with the microcontroller through the Serial UART communication protocol, allowing for bidirectional data transmission—both sending and receiving data are managed by the Bluetooth module itself.
RF433 Transmitter operates at a 433 MHz radio frequency within the Industrial, Scientific, and Medical (ISM) band. It is designed to transmit wireless data signals using On-Off Keying (OOK) or Amplitude Shift Keying (ASK) modulation techniques. These are among the most common and efficient methods used for short-range wireless communication.
