An EEG monitor with sensors placed to detect signals and analyze the signals to determine if a frequency below 12 Hz, and more particularly between 3 Hz and 8 Hz, called theta waves, are present. Theta waves are generated when the brain is entering a drowsy or sleep mode. The sensors detect brain wave signals and transmit the signals to a microprocessor which analyzes the signals and determines the brain waves being detected. The brain waves are continuously monitored and the data is continuously transmitted to a microprocessor. If brain waves are detected in the predetermined range of between 3 Hz and 8 Hz the microprocessor activates a stimulus, to wake up the person wearing the device. The stimulus may be visual, auditory or tactile, such as an actuator, a phone call or any other stimulus.
