10+ Ldr Circuit Diagram With Relay

10+ Ldr Circuit Diagram With Relay. Also, we will not demonstrate only one circuit but instead, three circuit will be put under the microscope. Below is the circuit diagram of this light sensing street light project.

The top circuit diagram shows an LDR (light sensor … from www.afiata.com

Control the relay by programming the pin to low or high. Led will turn on at the same time with relay. Automatic night light using ldr.

An ldr is used in this circuit for sensing the light and dark conditions.

10+ Ldr Circuit Diagram With Relay. A light / dark activated switch is a circuit that will somehow measure the light level and will turn on or off a relay accordingly. As the level of illumination on the ldr gradually changes, a potentiometer is used to set the appropriate voltage level of activation of the relay. Automatic night light using ldr. We will use an ldr (light depended resistor) to measure the light level.
