Infra-Red Remote Tester

Schematic Diagrams      Comments Off on Infra-Red Remote Tester

This little circuit is invaluable for quick go/no-go testing of just about any remote control transmitting infra-red (IR) light. The tester is battery-powered, built from just a handful of commonly available and inexpensive parts, and fits in a compact enclosure. Schmitt trigger gate IC1f is used as a quasi-analogue amplifier… Read more »

Infrared (IR) Proximity (Distance) Sensor

Schematic Diagrams      Comments Off on Infrared (IR) Proximity (Distance) Sensor

The photodiode can be used to detect IR reflected from the object. However, IR produced by the ambient conditions also detected by the photodiode. This IR noise must be filtered to prevent false detections. Usually, the LED’s IR signal is modulated with a convenient frequency and then using that modulation… Read more »
