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

A fully-operational and field-tested photovoltaic plant that automatically sets the optimal angles based on time and location.
Mark your calendars: May 23rd-25th we’ll be at SPS Italia, one of the country’s leading fairs for smart, digital, sustainable industry and a great place to find out what’s new in automation worldwide. We expect a lot of buzz around AI for IoT applications – and, of course, we’ll come prepared to give our own, open-source perspective on the AIoT trend. At Arduino Pro’s booth C012, pavilion 7, our experts will be presenting some of the latest additions to our ever-growing ecosystem, which includes everything companies need to fully embrace digital transformation with professional performance paired with Arduino’s ease of use and open-source philosophy. You can explore our complete digital brochure here, but let us point out some recent highlights. Meet the Arduino Pro ecosystem at SPS Italia 2023 Over the years, Arduino Pro has built quite the presence on the market with SOMs like the Portenta H7 and X8, recently joined by the Portenta C33: a cost-effective, high-performance option that makes automation accessible to more users than ever, based on the RA6M5, an Arm® Cortex®-M33 microcontroller from Renesas.Our Nicla family of ultra-compact boards also expanded: after Nicla Sense ME and Nicla Vision, Nicla Voice packs all the sensors, intelligence and connectivity you need for speech recognition on the edge, leveraging AI and ML. What’s more, the Arduino ecosystem also includes turnkey solutions like the Portenta Machine Control and the new Opta, our very first microPLC, designed in partnership with Finder to support the Arduino programming experience with the main PLC standard languages – and available in 3 variants with different connectivity features: Opta Lite, Opta RS485, and Opta WiFi. Both the Portenta Machine Control and Opta can be programmed via the new PLC IDE, designed to help you boost production and build automation with your own Industry 4.0 control system. Finally, since SPS Italy’s last edition we have
