Device for measuring concentration degree of brain

The invention discloses a device for measuring the concentration degree of the brain. The device for measuring the concentration degree of the brain comprises a brain wave collecting module, a Bluetooth transmission module, a control module and an indicator light module. The brain wave collecting module comprises a TGAM core control unit and a power source. The TGAM core control unit is composed of a biological signal sensor TGAT chip and a peripheral circuit of the biological signal sensor TGAT chip. The control module is composed of an Arduino single board computer controller and a peripheral circuit of the Arduino single board computer controller. The device for measuring the concentration degree of the brain is simple, convenient to use, small and low in cost. A measurement result is clear at a glance. The device is suitable for daily use by an ordinary crowd, and a scientific analysis method suitable for the ordinary crowd is provided for the development of the intelligence of people and the improvement on the attention of children in the education process.
