My project is automatic street light controller with light intensity variation at night based on human detection.The lights will be on with 50% power when there is no human detection by the pir sensor and light intensity will be maximized when person is detected.
I’m sorry bt i didnt clearly understand the last option on feeding the output of the ldr circuit (which is analog) to mcu directly, is that possible by suitable coding or something or is it done using some circuit ?
