The AutronX AU–X300 is a light-dependent resistor (LDR) sensor timer designed to automate lighting control based on ambient light levels. With an adjustable sensing range of 5–500 LUX, it triggers connected loads like lamps or streetlights to switch on or off depending on light intensity. Featuring a built-in timer (1–9 hours), the AU–X300 ensures efficient energy usage by controlling light operation duration. Its robust design is suitable for outdoor applications such as garden lighting, signboards, and township street lights, providing seamless day/night automation.
