Infrared light reflected off a finger is used to activate this switch circuit. Drawing only 30uA from a 3v supply, this circuit will detect a human finger with a range of about 1 inch. The sensor uses an inexpensive infrared LED and a matching photo diode... -
Below is the circuit I`m working with; I plan on having the infrared phototransistor pairs inserted in 3 locations in the middle of the maze, including the end point. The width of the maze will be small enough for one finger to be able to slide in it, and as.... -
For one of my classes each student had to pick one of three technology platforms to design, simulate, prototype and then build (PCB layout, ordering, etc) all within ten weeks. The platforms were: H-bridge Motor Controller, Infrared Proximity Sensor and.... -
This page is going to describe the parts, schematic, softw1are, and some tips on using Infrared for object detection. The parts used are typically the same parts found in most consumer electronic remote controls, and are widely available. If you have an old.... -
This add-on circuit enables remote switching on/off of battery-operated toy cars with the help of a TV/video remote control handset operating at 30 40 kHz. When the circuit is energised from a 6V battery, the decade counter CD4017 (IC2), which is configured.... -
The infra-red (IR) toggle switch project described here is aimed to provide control mechanism for electrical appliances that do not have remote operation features. The goal is to construct a black box where you can plug-in your 120V AC appliance and control.... -
Here is the circuit diagram of an infrared motion detector that can be used to sense intrusions. Infra red rays reflected from a static object will be in one phase, and the rays reflected from a moving object will be in another phase. The circuit uses this.... -
Chris from PyroElectro.com has a great article about a do-it-yourself radar system build with PIC18F452. It’s a great hobby project although the schematic is very complicated. This project uses three main devices to create a personal radar system. The IR.... -
Normally, home appliances are controlled by means of switches, sensors, etc. However, physical contact with switches may be dangerous if there is any shorting. The circuit described here requires no physical contact for operating the appliance. You just need.... -
All distances mentioned before can vary, depending on infra-red transmitting and receiving LEDs used and are mostly affected by the color of the reflecting surface. Black surfaces lower greatly the device sensitivity. Obviously, you can use this circuit in.... -
