Analog Light Sensor LX1972

Light sensors are probably one of the most common sensors in life, they can be found in your laptop,

phone or home lighting system. A light sensor measures the level of light in a room or ambient light in

a space.

This analog light sensor uses LX1972 as its ambient light sensing part, with spectral response that

closely emulates human eyes. It helps you to to detect the light density and reflects the analog voltage

signal back to Arduino controller. You can set the threshold of voltage level to trig other units on

Arduino project.

Notice: The new version of analog sensor port pin mapping has been changed as the following two

features.Please check the tips for changing sensor cable pin mapping while using the I/O Expansion

shield. We will continue to update. For the inconvenience caused, please understand.

Features

• Near Human Eye Spectral Response and Very Low IR Sensitivity

• Temperature Stable

• Scalable Output Voltage

• Output with Low Fitler(<50Hz)

Specifications

• Supply Voltage: DC 3~5.5V

• Operating Temperature: -40~80°C
