TSL Gy -2561 Lux Sensor is a light sensor with flat response across most of the visible spectrum.  It measure both infrared and visible light to better approximate the response of human eye and capable of measuring both small and large amounts of light by changing the integration time. It has selectable detections modes. It has programmable interrupt function with user defined upper and lower threshold settings.

Light Intensity Sensor Module (GY-30) use BH1750FVI chip. It has built in 16bit AD converter with digital output.    It is suitable for obtaining the ambient light data for adjusting LCD and Keypad backlight power of Mobile phone. It measure the ambient light intensity from 0 to 65535 Lux (L) range with direct output in Lux.

The 4-Channel IR Sensor Array Module is a compact and efficient infrared sensor module that combines four IR transmitter-receiver pairs arranged in a linear array. It is designed for multi-point infrared sensing, making it ideal for applications like line-following robots, edge detection, and surface pattern recognition. Each channel operates independently and detects changes in reflectivity, allowing the module to differentiate between dark and light surfaces (e.g., black line on white background).

Specifications (Typical):

• Sensor Type: 4-Channel Infrared Reflective Sensor Array

• Number of Channels: 4 independent IR pairs

• Detection Method: Infrared reflectivity (light/dark surface)

• Output Type: Digital (typically HIGH/LOW for each sensor)

• Operating Voltage: 3.3V – 5V DC

• Output Format: 4 separate digital output pins (1 per sensor)

• Detection Distance: 2 mm to 12 mm (depends on surface)

• Response Time: <1 ms
