What is a Illuminance sensor?

An illuminance sensor is a device designed to measure the brightness (illuminance) of the surrounding environment. It converts light intensity into electrical signals using light-detecting elements such as photodiodes or phototransistors. These sensors are widely used in applications like homes, offices, automobiles, agriculture, street lighting, and electronic devices. They play a key role in adjusting lighting automatically based on environmental changes and promoting energy-efficient usage.

Application of Illuminance sensor

✅ Smart Appliances
Integrated into lighting devices to automatically adjust brightness based on ambient light.
✅ Car Headlights
Detects low light conditions at night or in tunnels, automatically switching on or adjusting headlights.
✅ Agricultural Greenhouses
Monitors sunlight changes and controls supplementary lighting to optimize crop growth.
✅ Streetlight Management
Enables streetlights to turn on automatically at dusk or during cloudy weather, saving energy.
