- Velocity : less than 10Kbps
This module will transmit up to 90m in open area.
- Working voltage: 5.0VDC +0.5V
- Working current:≤5.5mA max
- Working method: OOK/ASK: On-Off Keying - denotes the simplest form of amplitude-shift keying (ASK) modulation that represents digital data as the presence or absence of a carrier wave. Amplitude-Shift Keying - is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave. In an ASK system, the binary symbol 1 is represented by transmitting a fixed-amplitude carrier wave and fixed frequency for a bit duration of T seconds. If the signal value is 1 then the carrier signal will be transmitted; otherwise, a signal value of 0 will be transmitted.
- Working frequency: 315MHz-433.92MHz
- Bandwidth: 2MHz
- Sensitivity: excel –100dBm (50Ω)
- Transmitting velocity: <9.6Kbps (at 315MHz and -95dBm)
433mhz Antenna Boost Notes :
The first rule about good reception is to have a good antenna. The use of an optional antenna will increase the effectiveness of your wireless communication. When using an external antenna a 1/4 wavelength is recommended. Ideally use 50 impedance ohm single-core wire, the length of the antenna 433M is about 17cm (1/4 wavelength). When locating the receiver antenna keep it as far away as possible from shielded areas, high voltages, and any other possible interfering frequencies.
