Light Alarm Circuit With Ldr. By connecting an ldr in series. light detector with ldr: this musical light alarm circuit is very simple, uses only 7 components, a ldr and a 3.6 v battery or 3 x 1.2 volts. Learn how to build your own light sensor using an ldr. when enough light falls on the ldr in this circuit, an alarm tone is played on the loudspeaker. These circuits are mostly triggered by the absence or the presence of light on the ldr. This circuit detects light incident on the ldr and turns on led whenever the intensity of light is greater than a certain level. This is a four transistor light activated alarm circuit for beginners. in this tutorial we’ll learn how to make a light sensor circuit using ldr (light dependent resistor), 555 timer ic and a few other electronics components. in this post i have explained 9 ldr circuit projects that uses ldr light sensor to trigger a load on/off through a relay.
