Remote control - 433MHz

Product detailed description

Complete set for wireless transmission on 433 MHz frequency, i.e. transmitter and receiver. Simple wiring, perfect usability up to 100 meters. Can be used for communication between two boards Arduino, possibly one control board and several satellite boards.

Specifications:

Receiver:

• Power supply: DC 5V
• Current: 20-28mA
• Frequency: 433.92MHZ
• Sensitivity: -105dB
• Size: 30x14x7mm
• The receiver has a reversed logic on the output - at rest the output is in HIGH and after receiving a LOW signal the output also changes to LOW.

Transmitter:

• Range: 20-300 Meters (depends on voltage)
• Power supply: 3.5-12V
• Current: 4mA
• Working mode: AM
• Speed : 4KB/S (theoretical value)
• Transmission power: 10mW
• Frequency: 433.92MHZ
• Size: 19x19mm

Handy 433MHz antenna (not included)

This is the most common design, it is not a problem to reach several hundred meters with it, but it has great demands on precision.

Better try a plain straight wire 17,3cm long ( length = 7500 / 433, i.e. a quarter of the wavelength ), the gain is not bad at all and you can transmit with it even on 100m

Anyway, modules without antenna have a range of tens of centimetres at most

Included in delivery:

• 1 pc 433MHz wireless module transmitter or 1 pc 433MHz wireless module receiver (your choice)

Remark:

• This product is not a standalone functional unit and may require professional installation.
