Description:  This module is compatible with various MCU control boards, such as MCU. Module contains 2 kind of interface for you . One is the anti-reverse insertion white terminal with a pitch of 2.54mm,we can use the module's own wire to connect to the microcontroller. To facilitate wiring, we also specially designed an extension that is fully compatible with this module and UNO R3 microcontroller board. The other is a pin header with a pitch of 2.54mm, using male-to-female DuPont cable, which can be straight connected to the microcontroller.     Specification:  Working voltage: DC 5V-15V.  Quiescent current: <20uA.  Interface: Anti-reverse interface PIN interface.  Hole size: 3mm in diameter.  Trigger mode: L can not be triggered repeatedly / H can be triggered repeatedly.  Maximum detection distance: 7m.  Sensing angle: <100 degree cone angle.  Wire length: 200mm.  Control signal: digital signal.  Light color: warn light.  Size:37*26*25mm.  Weight: 6.8g.     Package included:  3 x Human Body Infrared Pyroelectric Sensor (the other items are not includes)
