Light sensor with three ranges

Description

Durable and versatile light sensor. The 0 – 1500 lux range is the most sensitive range, it is suitable for low levels of illumination. The 0 – 15000 lux is a good general-purpose range for indoor light levels. The 0 – 150000 lux range is suitable for measurements in daylight. Full sun illumination is within the range of the sensor. The sensor can also be used as a light gate.

Technical specifications:

• Measurement ranges: Ranges: 0 .. 1500 lux / 0 .. 15000 lux / 0 .. 150 000 lux
• Resolution: 0.37 lux / 3.7 lux / 37 lux
• Wavelength of peak sensitivity: 565 nm
• Range of spectral bandwidth: 420 nm .. 675 nm
• Maximum measurement frequency: 100 kHz (CoachLab II+, WiLab) / 1 MHz (VinciLab 2)
• Required: One sensor cable (BTsc_1 or BTsc_1Short)
• Warrantee: 3 years

All technical specifications of the sensor are described in the product manual, see downloads.

The Light sensor can be used in a variety of experiments in biology, chemistry, physics or environmental science, such as:

• Verifying inverse square law
• Observing darkening of a solution caused by a chemical reaction
• Investigating reflection and absorption light,
• Studying weather – monitoring sunrise and sunset times,
• Studying solar energy,

and digital applications (as a light gate) such as:

• Measuring the acceleration due to gravity
• Measuring the speed of a moving cart.
