System components – wireless sensor network

In a wireless sensor network the following system components play a major role in the wireless transmission of data:


The aim of wireless data acquisition and synchronous data transmission in a wireless sensor network is the data collection of various types of sensors. Therefore, our system is suitable for the acquisition of various sensors from industry and research.

Tediasens radio nodes

With our Tediasens SN-X  sensor node you can record the data from three external sensors and with the SN-I radio node you can capture vibration and acceleration through an integrated industrial accelerometer. TEDIASENS radio nodes are a fundamental part of a system for wireless data transmission. With the newest wireless technology, the recorded data can be transferred quickly and synchronously to the WLAN access point.

WLAN Access Point

WLAN Access points are the “base stations” in a wireless sensor network and serve the wireless data transmission to our wireless access point for synchronous data analysis with our analysis software tools. The WLAN access point is connected via USB interface to a PC.

Supported sensors

  • Acceleration sensors
  • Force sensors
  • Rotational speed sensors
  • Light barriers
  • Microphones
  • etc.

These are just some examples of the sensors which are suitable for wireless data acquisition and data transmission with our Tediasens system. A full list can be found under the menu item “Supported sensors”.

Synchronous data transmission

Synchronous data transmission exists, when the data transfer between the transmitter and receiver is synchronized with a clock signal in time. Synchronous data acquisition and synchronous data transmission is applicable primarily in wireless sensor networks, where synchronous data transmission is used to transmit the sensors signals relayed to various wireless sensor nodes to an access point so that it can collect the data from all sensors synchronously.
