InfraRed Detector for Proximity Switch
The proximity switch can work for a wide range of power, from 8v to 18v DC, D3 protects reverse power supply connections, and U1 regulates the supply to +5v , -5v is derived from...

This is an Application note i used to give with my ssr – app012.pdf Diagram of SSR 5000 DC 3-30 Control / 230V AC N.O. @ 3A.
I’m working on a small electronics project but don’t know too much about designing circuits so I figure I would ask someone who knows and this seems like the place. Ok, What I’m looking...
Thank you for your assistance. My answers are by your questions. Hope this helps. This unit is more for troubleshooting a air flow problem. If the counter shows many 130 Degrees detected or alarm...
I’m looking at an idea for a circuit design; The idea is to sense a temp of 130 degrees and then light an LED and start a timer delay. The delay would be 3...
A Center tap 50Hz Step Down Transformer with two diodes is used to get a train of Positive Sine Pulses at 100Hz which is applied to Q6 base via R51. 2N2646 is a unijunction...
In this circuit we tackle the error indicated in the earlier Current Source. The LM336-2.5V eliminates the tiny error of the regulated supply and resistors. Thereby increasing Precision to a higher degree.
This Circuit is a DPM or digital panel meter. It has a analog bar graph display and a 3-1/2 digit digital display. ICL7107 is used in the 200mV configuration. U4A opamp LF353 amplifies the...
