Overview
The RCWL-0516 is particularly suitable as an alternative to using a PIR motion sensor.
When it detects a moving object, the output changes from a low logic level to a high level (3.3 volts). Appropriately interfaced (Arduino, Fishino or other), it can be used for the automatic opening of electric doors and gates, automatic lighting.
Detection range is about 9 meters.
Tech specs
- Power supply: from 4 volts to 28 volts
- Consumption: typical 2.8 mA; max. 3 mA
- Detection distance: from 5 to 9 meters
- Transmission power: typical 20 mW; max. 30 mW
- Output voltage and current: 3.2-3.4 volts - 100 mA
- Operating temperature: from -20°C to +80°C
- Pin definition: 3V3: 3.3 volt output voltage
- GND: negative power supply
- OUT: when it detects a moving object, it changes from a low level to a high level (3.3 volts)
- VIN: positive power supply from 4 volts to 28 volts
- CDS: if kept low, less than 0.7 volts, the output will always be low even in the presence of motion

Install FLECS Marketplace on the Portenta X8

FLECS and Arduino Pro are partnering to make Industry 4.0 easier for you. FLECS is the easy-to-configure and open-source platform that allows industrial users to work with automation solutions dedicated to their machinery just as easily as we all handle the apps on our phone: install, manage and configure via web interface, and let the system keep track of versions and ensure updates. All you need is a Portenta X8 – our powerful, industrial-grade SOM with Linux OS preloaded onboard: connect it to your computer via USB, install FLECS for free (with, literally, one line of code), and access the FLECS UI to pick the right solution for production control, communication, SCADA (Supervisory Control And Data Acquisition), data analysis, fleet management and more. Deploying Linux applications has never been more straightforward: we could say it’s as easy as 1-2-3 – except there are actually only 2 steps to the whole process. “We are excited to offer the huge Arduino user community immediate access to our automation applications, so anyone can build and boost a wide variety of solutions for industrial contexts. It’s all made possible by Portenta X8, a groundbreaking product bringing Linux into the Arduino ecosystem.” – Patric Scholz, Managing Director at FLECS Indeed, while on one side you can now leverage all FLECS solutions in a few commands and clicks, on the other you will be working with one of Arduino Pro’s highest-performance modules: Portenta X8 is basically two industrial products in one, with the power of no less than 9 cores (an NXP i.MX 8M Mini Arm® Cortex®-A53 quad-core, up to 1.8GHz per core + 1x Cortex-M4 up to 400MHz, plus the STMicroelectronics STM32H747 dual-core Cortex-M7 up to 480MHz +M4 32-bit MCU up to 240MHz). And of course, the “superpower” of all Arduino products: being part of a comprehensive ecosystem of open-source hardware, software solutions, Cloud services and amazing community-based support.
