This package includes 3 pieces of ir break beam sensor switches,constructed with a plastic casing and metal pins for stable connections. The sensor consists of a transmitter and receiver pair that detects obstacles when the infrared beam is interrupted. It's a basic light sensor moudule essential component for various electronic and automation setups.
As a photoelectric switch, this device operates by emitting an invisible infrared beam; when an object blocks the beam, the switch triggers a signal change. It has a detection distance of up to 30cm, making it suitable for short-range sensing tasks. The simple design allows for quick wiring without complex calibration steps.
Designed as a light sensor module, it features built-in voltage regulation, supporting 5V DC input, which is compatible with most microcontrollers.The module includes indicator LEDs that show power and detection status, helping users troubleshoot connections easily during setup.
This remote switch ir sensor can be paired with wireless modules for remote control applications, such as automatic door openers or security alarms. Infrared sensor compact size enables installation in tight spaces, like inside small appliances or DIY robot projects. The non-contact sensing method reduces wear compared to mechanical switches.
Beyond basic sensing, it functions as a photocell ir beam device, responding to infrared light changes, and can be used alongside a laser photoelectric sensor for enhanced precision in projects requiring accurate object detection. It's also a versatile alternative to a distance sensor for simple presence detection tasks in hobby or industrial projects.
