LDR & LED Smoke Detector

Smoke detectors are generally used in advanced alarm systems. Most of this professional devices use gas-detectors, ionization rooms or radioactive elements as sensors. In this circuit we are not using any of this complicated components. Instead of these, we are using two LDRs and one LED. LM1801 special-purpose IC , which is designed especially for smoke detectors, provides us building this circuit by using the minimum number of components. It includes one internal zener supply, two referenc.......

Short dc power-line pulses afford remote control - 2001-10-25 07:00:00 | EDN

If you face the challenge of adding a second, independently controlled light source to an existing ceiling lamp controlled by a wall switch, you may find that stringing a second power line is impossible. First, you can replace the wall switch by the circuit in Figure 1. Pushing the on switch S1 or S2 for approximately 1 sec inserts the 12V zener diodes D1 or D2 in series with the ........

KA431 PDF Datasheet Adjustable/2.5 V

The KA431 / KA431A / KA431L are three-terminal adjustable regulators with a guaranteed thermal stability over the operating temperature ranges. The output voltage may be set to any value between VREF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0. 2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications........

High Power Zener Diode Circuit

The high power "zener diode" circuit presented here can be used for obtaining a highly accurate, temperature and voltage stabilized outputs from high current sources, safely. The low power zener diodes that we normally use in electronic circuits are specified to work with low currents, and therefore cannot be used for shunting or stabilizing high current supplies. Although higher rated zener diodes are available, these could be relatively expensive. Nonetheless, it is actually possible to make a.......

12V Transformerless Power Supply

12V Transformerless Power Supply circuit diagramHere the low power 12V transformerless power supply circuit with full-wave rectification. A lot of circuits could be powered straightaway in the electric mains using the support of a series capacitor (C1). The problem with this method is the fact that typically only one half cycle of the mains wave-form can be used to deliver a DC voltage. An obvious option is to wor.......
