AS3079CKT - Light / Dark Activated Switch (Schmitt Trigger)
Product Formats Available : Pre-Assembled Module (AS) or Self-Assembly Electronic Kit ( Soldering Required)
This Light/Dark activated relay board switch uses an LDR and Schmitt trigger circuitry to eliminate the problem of relay chatter at the trigger threshold. This allows the switch to operate effectively where there is a gradual light change (i.e. dawn and dusk).
The Light/Dark mode switch is used to select either light or dark activation of the relay. This enables the unit to be operated in its low-current standby mode for the majority of the time according to your application.
Adjustable turn-on sensitivity
