With the wireless speed sensor you extend your possibilities of data evaluation. The transmitter reliably transmits your current speed, average speed and maximum speed. The STS speed sensor is compatible with all SIGMA STS devices.
STS speed sensor
The STS speed transmitters can be swivelled and can thus be aligned even better parallel to the magnet. The battery compartment of the STS speed transmitter is located on the outside, so that the battery can be easily changed even when mounted.
Digitally coded 3-channel radio transmission
The proven and reliable SIGMA TRANSMISSION SYSTEM (STS) is the digitally coded transmission system for all transmitter data from speed transmitters, cadence transmitters and also pulse transmitters for high-quality basic devices and top models. The transmitters collect their sensor data and send it as a digital data package to the receiver integrated in the computer. In addition, the transmitter regularly sends stored test data as data reconciliation.
The digital coding of the SIGMA TRANSMISSION SYSTEM prevents the transmitter data from being falsified by external interference such as power sources or other transmitters. Interference with SIGMA products, e.g. LED lighting, can be excluded.
