Internet of Things a new dimension Until now the Internet was blind the Internet only connects people at anytime and anywhere, but the environment of these people could not be connected With the Internet of Things a new dimension could be connected: ANYTHING Source: Journal Internet of Things
Internet of Things Definition according to Yole Développement Internet of Things devices is the aggregation of all sensing modules which are linked to the Cloud either directly or through a gateway and with which data is processed and valorized in any manner.

Example 1: power line monitoring Problem: increasing supply of renewable energies (e.g. solar and wind) and its high fluctuations Distribution of power from renewable sources is difficult (transport bottleneck) Safety margin (distance between power line and ground) reduce capacity utilization Goal: online monitoring of the power lines (temperature of the conductor, magnitude of the current, conductor sag) Monitoring system allows evaluation and optimization of the capacity utilization
power line monitoring Outer conducting hull Harvester electronic Filter
power line monitoring Sensor nodes suspended at intervals of a few hundred meters along the high-voltage power line (e.g. at 110 kv or 380 kv) Transmission of sensor values (inclination, temperature, current) along the chain to a base station Self-organization of the network Wireless communication in 2.4 GHz frequency band Energy required to operate the system is harvested from the electrostatic fringing field of the power line
Characterization Field test at a 110 kv power line Measurement of temperature and inclination Approval of the concept: power transmission can be monitored by measurement of inclination Wireless communication in 2.4 GHz frequency band Energy needed is harvested
Example 2: Grease Sensor Condition of the machine [%] Chemical/Physical modification vibration noise generation of heat overheating Pre warn time (standardized) Approximately 80 percent of all damages to greaselubricated bearings are caused by lubricants. Currently available sensors (structure-borne sound) are inapplicable, as they only detect a damage, which has already occurred. With grease sensors it is possible to detect changes of state in grease long before damages to bearings occur. Thus, the replacement of grease can be defined precisely.
Grease Sensor Solution printed circuit board Sensor case Primary electronics optical window
Grease Sensor Solution Measurement categories: Temperature Grease damage Contamination (abrasion, water) Grease degradation (aging) Parameter: Supply voltage: 12 36 V Range of temperature: 05 85 C Protection standard: IP68 Communication interface: Power output (4 20 ma) Switching output (0 24 V) CAN-Interface Others: Short-circuit proof Overload protection Inverse-polarity protection
Example 3: smart Sealing Ring Current industrial trends aim particularly at the functional integration of sensors in machine parts: Minimization of system errors Preservation of competitive advantages Seals are suitable machine parts, as they separate critical elements from anothers Challenges are in the: Development of novel multifunctional sensors Energy supply as well as communication opportunity, integration to an overall working system.
smart Sealing Ring Electronics & Signal Transmission Challenges Reliability (range of temperature: -40 - +120 C, lifetime: 10 years) Aggressive surroundings (oil) Functions Measurement of: temperature, wear out of the seal and rotation speed every 3 seconds Rectification of the generator ac voltage SPI SPI MOSI 1 MISO 1 SCLK 1 μc CC2500 CC2500 CS 2 MOSI 2 MISO 2 SCLK 2 CS 3 μc TXD RXD USB
