Uses of Electrical Timers
Mechanical Timers: Operate using gears and springs, requiring manual adjustment.
Digital Timers: Offer programmable settings and higher accuracy.
Plug-in Timers: Used for appliances like lamps and heaters, easily plugged into outlets.
Wall Switch Timers: Replaces standard wall switches to control lights and fans.
Astronomical Timers: Adjust according to sunrise and sunset times.
Programmable Timers: Allow multiple on/off cycles and customization.

Motion Sensors:

Types of Motion Sensors:
Passive Infrared (PIR) Sensors: Detect body heat and motion.
Ultrasonic Sensors: Use sound waves to detect movement.
Microwave Sensors: Emit microwaves and detect motion through Doppler effect.
Dual Technology Sensors: Combine PIR and microwave or ultrasonic for reduced false alarms.
Tomographic Sensors: Use radio waves and detect motion over large areas.

Uses of Motion Sensors:
Security Systems: Detect intruders and trigger alarms.
Automatic Lighting: Turn lights on/off in homes, offices, and streets.
Energy Savings: Reduce power consumption in unoccupied areas.
Smart Home Automation: Integrate with smart devices for convenience.
Industrial Applications: Monitor machine operations and automate processes.
