5Pcs 433MHz RF Wireless Transmitter and Receiver Module Kit for Arduino ARM MCU and for Raspberry pi

The Receiver Module (Rectangle Shape): Working voltage: DC 5V Static current: 4MA Receive frequency: -105DB External antenna:32cm single core wire would in helix Size :30*13.5*7mm The Transmitter Module (Square Shape): Operating Voltage: 3.5-12VDC Size: 19mm x 18.9mm AM transfer rate: 4KB / S Transmitting Power: 10mW Amplitude Modulation: ASK or OOK Transfer Rate: <10Kbps Working method: AM Transmission frequency: 433.92MHZ External antenna: 25cm single core wire, coiled into a spiral Pinout from left to right: (DATA; VCC; GND) Launch parameters: Launching distance: 20-200 meters(different voltage, different effect) Working voltage:3.5-12V Shape size:19*19mm Working mode: AM Transmission rate:4KB/S Transmitting power:10 mW Transmitting frequency:433.92M External antenna:25CM ordinary multi-core or single-core wire Pin alignment(left to right):DATA; VCC; GND Notice: The distance will be influenced by its working voltage, rainy or thunderstorm day, signal shielding device, signal interference source, high-tension power wire. Better to keep the modules from them. Applications: - These modules are used for projects when you need to communicate wirelessly between 2 devices. It is possible to increase the range by adding a small length of cable which the device will use as an aerial. - It is very popular for remote control systems, such as Remote control rolling gates, smart car, smart home, etc. Package Included? 5*433MHz RF Wireless Transmitter and Receiver Module
