Overview
The resistance of photoresistor decreases when the intensity of light increases. A dual OpAmp chip LM358 on board produces voltage corresponding to intensity of light(i.e. based on resistance value). The output signal is an analog value, the brighter the light is, the larger the value.
This module can be used to build a light controlled switch i.e. switch off lights during day time and switch on lights during night time.
Warning!: The light sensor value only reflects an approximated trend of light intensity, it DOES NOT represent the exact Lumen count.
Features
- Analog value output
- High reliability and sensibility
- Small footprint
- Recognizes a wide spectrum

During Bett Show 2020, Arduino will launch the Arduino Education learning evolution: four new STEAM products for students in lower secondary school through to university. Arduino Education will also announce a partnership with the Fraunhofer Initiative: “Roberta – Learning with Robots” in Germany. Arduino Education's latest products — CTC GO! Motions Expansion Pack, Engineering Kit Rev2, Arduino Education Starter Kit, and IoT Starter Kit — will be unveiled at Bett and available in Q1. These new products complement the existing portfolio, which includes the Science Kit, CTC GO!, CTC 101, Arduino Starter Kit, and Certification program. Arduino CEO Fabio Violante comments: “We are delighted to announce four new products which will expand STEAM learning for lower secondary to university students. Our technology, programming, and curriculum content are creative tools — just like brushes and paint — that students can use as they become part of our next generation of scientists and artists.” CTC GO! Motions Expansion Pack (Age: 14+) Build on your secondary school students’ STEAM knowledge with more complex programming concepts that develop computational thinking and 21st-century skills. For educators who have taken their students through the CTC GO! – Core Module, the Motions Expansion Pack builds on what they have already learned about how to use technology as a tool and how to apply that knowledge in the real world. The Motions Expansion Pack challenges students to go a step further in computing and design while introducing them to motors and transmission mechanisms such as pulleys and gear concepts that develop their logical reasoning, hands-on building skills, and problem-solving skills. Educators get all the teaching support they need with webinars, videos, guides, and direct contact with an expert. Engineering Kit Rev2 (Age: 17+) Challenge upper secondary school and university students and help them develop hands-on
