Bluetooth Wifi Module Wheel Aligner Module

SL-2A1 module is one of our company's industry modules, specially aiming at wheel aligner R&D, design and production. Comparing with traditional one it has more advantages.

Most traditional wireless aligner modules use the light (the infrared ray and light) to transmit the data and information. However, because of the short transmission distance and the directionality of light that makes the shelter by operator, it is easy to cause unstable. Meanwhile, advanced Bluetooth module makes no barriers of information transmission and has improved the rate of accuracy of data transmission greatly. With Bluetooth technology, it can be installed into Wheel Aligner and computer, between which data transmission is accurate and clear in the range of 10 metres.

With FHSS technology, it can't be interfered by the same frequency signal of other equipment at repair place. It is unique comparing with traditional ones. Furthermore, Bluetooth module adopts omnidirectional antenna, more easily to find device. It Supports the terminal movement. Signal transmission is not affected by sight distance .It is full-duplex, supporting the connection of point to multi-point and facilitating to group network.

Performance contrast
bluetooth infrared ray the common radio frequency

directivity:
bluetooth not limit to direction
infrared ray must keep an angle below 30 degrees with the device
the common radio frequency limit to direction

transmission distance:
bluetooth 10m(or 100m)
infrared ray about 1m
the common radio frequency about 10m

anti-jamming:
bluetooth (with 1600frequence/sec.FHSS technology)not affected by barrier
infrared ray affected by barrier
the common radio frequency having some antijamming ability

security:
bluetooth high
infrared ray high
the common radio frequency low

power consumption:
bluetooth low
infrared ray low
the common radio frequency high

grouping network:
bluetooth yes
infrared ray no
the common radio frequency yes
