Claim 0:
1. A safety control system for a portable weapon, comprising:
a microcontroller for controlling a driver to drive an actuator for actuating a lock mechanism; and
a vital sign detection sensor being in communication with said microcontroller and to detect a human in a direction to which said portable weapon is pointing; wherein said microcontroller determines to control said driver to drive said actuator to actuate said lock mechanism to lock a firing sequence of said portable weapon based on a detection signal from said vital sign detection sensor;
wherein said vital detection sensor is a body temperature sensor comprising:
a pyroelectric infrared sensor;
a Fresnel lens having a first side with a smooth surface and a second side with patterns, said second side facing with said pyroelectric infrared sensor; and
a cylindrical housing member for housing said pyroelectric infrared sensor at one end, and said lens disposed at a focal distance of said lens away from said pyroelectric infrared sensor.
