Motion sensor circuits are there on the Internet for quite a while now. These circuits are mainly used to drive AC load (like lights, fans) in home automation or IoT projects. It is also very common ...

This is a ready-to-deploy Websocket based relay server with caching support. Please refer to the flow diagram at the end of this document for a detailed overview. Additionally, the relay server also ...

Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...

This simple temperature relay circuit can be used to signal a fire or setpoint for temperature monitoring function. You need to adjust P1 so that T1’s base voltage is 0.5V smaller than the emitter ...

Some control applications are too small or simple to use even the smallest PLC, but still need more flexibility than a simple relay. That's why engineers at Schneider Electric, Palatine, Ill.

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...
