The package contains: 1 x Pair transmitter Tx + receiver Rx 433MHz
Pair of modules for wireless serial data transmission (wireless) in the 433 MHz band. The range is from 20 to 200m depending on the supply voltage and you can send data in ASK/OOK coding up to a speed of 10kbps. To increase the range you can solder on the pad marked ANT a piece of insulated wire about 17cm (1/4 wavelength) or 25cm (1/2 wavelength) long on the transmitter and 16 or 32cm spirally wound on the receiver. Both boards require antennas for proper operation.
Possible applications: remote switches and drives, anti-theft and security, doors and gates, model making, etc.
Power: 10 mW
Range: up to 200 m at 12 V
Power supply: 3.5 Vdc - 12 Vdc
Baud rate: 4 KB/s
Frequency: 433.2 Mhz
Power supply: 5 Vdc
Absorption: 4 mA
Sensitivity: -105 dB
Frequency: 433.92 Mhz
Performance may vary depending on supply voltage, the installation or not of a suitable antenna, the presence of obstacles (such as walls and shielding) and the radio saturation of the 433MHz band in the area of use.
