Infrared beam barrier/ proximity sensor -  his circuit can be used as an infrared beam barrier as well as a proximity detector.  The circuit uses the very popular Sharp IR module.  The pin nos.  shown in the circuit are for the Sharp module only.  For other modules please refer to their respective datasheets __ Designed by Radioland.nt.au

Magnetic Proximity Switch -  Here is an interesting circuit for a magnetic proximity switch which can be used in various applications. The circuit, consists of a reed switch at its heart.  When a magnet is brought...__ Electronics Projects for You

Motion Detector Alarm -  This motion detector alarm circuit can detect a moving person from a distance of 1 meter.  it uses a Dual IR Transmitter-Receiver module HOA1405.  When the sensor detects the reflected IR rays, Alarm will sound for 2 minutes.  The circuit can be modified for various applications including AC operated alarm systems.  Motion __ Designed by D Mohankumar

Motion Sensor for Security Light -  Here is a system based on PiR motion detector module BS1600 (or BS1700) that can be used for security or corridor lighting in power-saving mode.  The 12V DC power supply required...__ Electronics Projects for You

Motion Sensor Light Switch -  3-Sep-15 -Design News:   Are there light switches in your home that aren't as conveniently located as you would like? This laser-based switch decoder and driver allows for flexible control of those lights located in less than ideal places.  I live in an apartment.  My kitchen is boring and can be accessed from either end of __  Gadget Freak-Case #272

Person Detector -  This is a circuit thich I originally included in my book, 22 Tested Transistor Projects, published by BabanI Press in 1976 (iSBN 0 900162 63 S).  it is one I had great fun with.  it uses the PUT Complimentary Feedback Pair as a sensitive detector of changing electric fields to switch on an oscillator and make a noise.  it is so sensitive that it can be difficult to get it working on a test bench because of all the electric fields, but put it on a table and leave it.   __ Designed by Richard Torrens

Proximity Detector -  Here is a Simple, But Very Effective One.   __ Designed by G.L. Chemelec

Proximity Detector (uses human body capacitance) -  Schematic Only __ Designed by G.L. Chemelec

Proximity Detector with HOLD Times -  Here is a another Simple Proximity Detector, but with added Features.   __ Designed by G.L. Chemelec

Proximity Switch for 240VAC Lamps -  Just wave your hand near it to turn the light on or off.__ SiliconChip

Wireless Temperature & Humidity Sensor with USB -  this project is based on obdev's Remote Sensor example and their firmware-only USB implementation; the main change is the replacement of the analog sensors with a Sensirion SHT11 digital temperature and humidity sensor__
