Key Features:
-
Frequency Range:
- The modules operate at two common frequencies: 315 MHz and 433 MHz. These frequencies are often used in low-power, short-range wireless communication applications.
- 315 MHz is typically used for smaller range applications, while 433 MHz offers a longer communication range with slightly lower data rates.
-
ASK Modulation:
- Both transmitter (Tx) and receiver (Rx) modules use Amplitude Shift Keying (ASK) modulation, a basic form of digital modulation. ASK is ideal for simple, cost-effective wireless communication, typically used for low-bandwidth transmission like on/off keying or simple data packets.
-
Range:
- The effective range of these modules can vary depending on factors like power supply, antenna quality, and obstacles, but generally, they provide communication ranges between 50 meters to 100 meters in open spaces.
- The range may be less in indoor or obstructed environments.
-
Low Power Consumption:
- These modules are designed for low power operation, making them suitable for battery-powered applications like remote sensors, smart meters, or wireless devices.
-
Simple Communication:
- The modules are relatively simple to integrate with microcontrollers (such as Arduino, ESP8266, and ESP32), and are typically used in basic wireless communication projects.
- The data transmission is usually in the form of serial data, making it easy to interface with microcontrollers via standard serial communication protocols.
-
Wide Application Range:
- Commonly used in remote control systems, alarm systems, home automation, wireless sensor networks, and IoT applications.
- Can be used in hobbyist projects, security systems (like garage doors), and wireless keypads.
