Initeq IR Optical Limit Switch / Tachometer Speed Sensor Module For Arduino, ESP32, DIY Projects

Hey makers and tinkerers!

Here's a handy little IR optical sensor module from initeq.

It's super versatile—you can use it as a limit switch for a 3D printer or CNC machine, or you can hook it up to an Arduino or ESP32 to build a tachometer and measure RPM.

It works by using an infrared light beam that gets broken by an object.

It's a brand new module, made in China, and it's perfect for any electronics project where you need non-contact sensing.

Whether you're counting rotations on a wheel, homing an axis, or detecting jams, this little board is a simple and cheap way to get the job done.

It's unbranded but functional, and a staple part for any hobbyist's parts bin.
