We proposed an intelligent chair system with FPGA-based embedded systems. The power switch of the electronic equipment can be controlled by the intelligent chair system. When user sits on the intelligent chair, the electronic equipment is turned on. When user leaves, the electronic equipment is turned off. The pressure sensors are set in the intelligent chair. The signals of the sensors are dealt with a microprocessor. The system uses the Bluetooth transmitter to transmit the dealt signal to control power switch of the electronic equipment. The system can be controlled by interactive website. Using the intelligent chair system can achieve energy-saving purposes.
