Light / Dark Activated Dusk Dawn Sensor Relay Switch

AS3079BKT - Light / Dark Activated Dusk Dawn Sensor Relay Switch
Ability Level 2: ModerateMade in BritainProduct Formats Available : Pre-Assembled Module (AS) or
Self-Assembly Electronic Kit ( Soldering Required)

New improved version with 5 Amp mains rated relay output.

This board uses an LDR and built-in hysteresis of the 741 op-amp IC circuitry to eliminate the problem of relay chatter at the trigger threshold. This allows the switch to operate effectively with both fast and 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 light level trigger sensitivity
  • Switch to select either 'light' or 'dark' activation
  • LED status indicator
  • Mains rated relay
