Description
PIR (passive infrared sensors) sensors allow you to detect movement. Very often used in alarm systems. These sensors are small in size., inexpensive, consume little energy, easy to operate, practically not subject to wear. Except PIR, such sensors are called pyroelectric and infrared motion sensors.
