How To Make Solid State Relay | LDR Project

A Solid State Relay (SSR) is a relay that does not have a moving contact few scends to work. In terms of operation, SSRs are not very different from mechanical relays that have moving contacts.SSRs, however, employ semiconductor switching elements, such as thyristors, triac, diodes, and transistors.

Solid-state relays are the semiconductor equivalents of the electromechanical relays and therefore can be used to control electrical loads. to activate a single output load when energized.

LDR Sensor Module Relay is used to detect the presence of light / measuring the intensity of the light controller. The output of the module goes high in the presence of light and it becomes low in the absence of a light sensor.

What is LDR used for? Light Dependent Resistors are often used as light sensors or day-night sensors. They are usually utilized when it is required to detect the presence and absence of a light set or to measure the light intensity.

Resistors are connected in series Lines with LDRs when interfacing with microcontrollers to create a voltage divider circuit diagram. Because the Light Dependent Resistor is just a special type of resistor used.
