This is a simple circuit which controlls a relay with both LDR and PIR technology. you can supply 12v AC by connecting a 12v transformer to the 2 pinned **SCREW** header.If you dont have a transformer, you can directly connect a 6v battery to power this through the **'+DC6V' header**.
The LDR mode turns ON the relay when it's dark while the PIR mode turns ON the relay when theres a motion within...
Soft starter used to save plastic gears of modern cheap tools by applying less initial force. Angle grinder, Miter saw and other funny jumping during power on universal motor equipment will be happy.
* ZC detectors to syncronize TRIAC timings and detect power-on switch status on tool
* TRIAC to soft start motor from 30% to 100% power
* NOTE: Do not use smart tools with speed control...
when you supply AC12V to this device, It will controll a relay according to the light intensity. when it's dark, the relay turns ON and when there's light it goes off.
This circuit can be very usefull since most most of the components are surface mounted and it consumes only a little amount of space.This circuit can be useful when considering saving electricity as well.You can connect this to any...
This is a basic latching switch design that uses two push buttons to control the SSR attached to its output with a latching effect for use with industrial style push-buttons.
The working of the circuit can be seen on my YouTube Channel at: [https://youtu.be/4oSe95wAq4c](https://youtu.be/4oSe95wAq4c)
The 5V Relay Module KY-019 is perfectly made for Arduino application, is part of the "37 In 1 Sensor Module Board Set Kit For Arduino".
It has three pins, the VCC, GND and Signal. It can act as switch if the circuit and the load circuit have different supply voltage.
It is commonly use if the load circuit is AC. It is a switch used to connect isolated connection from the circuit using a circuit si...
