saba ultracolor p42s53 telecommander 05 circuit

This infrared transmitter is designed for use with an infrared receiver. It operates using either two 1.5V batteries or a 3V lithium battery, allowing for a compact infrared communication system. The infrared transmitter circuit typically consists of an infrared LED, a...

Infrared alarm barrier circuit

This infrared alarm barrier is designed to detect individuals passing through doorways, corridors, and small gates. The transmitter emits a beam of infrared light that is invisible to the human eye. When the light beam is interrupted by a person,...

reading electricity meter ir impulses

Yesterday, an attempt was made to read the infrared impulses from an electricity meter using a phototransistor. The phototransistor can detect infrared signals from various remote controls in the house but fails to detect the blinking signal from the electricity...

Visual modulation indicator

The brightness of the indicator lamp changes in accordance with the modulated RF signal. Adjust resistor R2 while the transmitter is on (modulated) until the lamp flashes in sync with the modulation. Cl = 5 pF, C2 = 100 pF, Dl...

Metering circuit using PbS PbSe

This circuit can be used for detecting infrared light; for example, it is utilized for detecting infrared band light signals in a spectrophotometer. The amplifier output voltage Vo is given by the formula Vo = Is·Rd·Rf/Ri, where Is is the...

Infrared Interruption counter

Infrared interruption counter is a reliable circuit that takes over the task of counting number of interruptions very accurately. When somebody enters into the room, then the Counter is Incremented by one. The total number of Persons inside the Room...

Infra Red Remote Control

This circuit is the result of research conducted by Andy Collinson. It employs a photodiode, specifically the SFH2030, as an infrared sensor. A MOSFET operational amplifier, CA3140, is utilized in differential mode to amplify the current pulses generated by the...
