Mini 3.3V RF Transmitter Receiver 433MHz for Arduino / 3.3V MCU
The kit includes one pair of transmitter and receiver modules. And the frequency is 433MHz. It is very popular for remote control systems£¬ such as wireless doorbell£¬ remote control rolling gates£¬ smart car£¬ smart home£¬ etc. About the transmitter module (square shape): - Compatible with Arduino - Arduino Library: VirtualWire - Working voltage: 3-12VDC - Working current: 3.5mA - Working frequency: 433MHz - Transfer rate: 4.8kbps (max) - Transmission distance: When the spring antennas are soldered to transmitter and receiver module and the power supply is 5V£¬ the open area transmission distance can be increased to 40 meters. The supply voltage is larger£¬ the transmission distance farther. - Antenna: You can use the wire whose length is 17cm or the spring antenna for 433MHz RF. About receiver module (rectangle shape): - Compatible with Arduino£¬ suitable for 3.3V MCU - Arduino Library: VirtualWire - Operating voltage: 2.5 - 4.5VDC - Working frequency: 433MHz - Working Current: 0.28mA (low power consumption) - Sensitivity: -105db - Antenna: You can use the wire whose length is 17cm or the spring antenna for 433MHz RF. - Great for DIY project.
