Global warming and air pollution are unfortunate consequences of our advanced industrialization. The time for a new way of interacting with our planet is long overdue.

Semefab's ultra low power CMOS ASICs with >3 year battery life play a small but important part in this process. Semefab's chips in PIR sensors automatically control lighting and avoid wasting energy making an excellent contribution. Our photopic light sensors automatically control light intensity of notebook screens and reduce the energy consumed in street lighting.

Our ASICs efficiently drive LEDs. The sensors we produce control

the efficiency of combustion engines and domestic heating systems, and assist in the cleaner generation of electricity from hydroelectric generators, wind turbines and nuclear power stations. All serving to greatly reduce our carbon footprint.

Semefab is playing our part and taking responsibility for helping to create a green future.
