Purchase options and add-ons

  • use: 1. +5 +5 is the positive input port of the power supply, which can be connected to a voltage of 3.3V~5V
  • 2. GND GND is the negative input port of the power supply. OUT OUT is the signal output port, which is connected to the I/O port of the single-chip microcomputer. Generally, it is connected to an external interrupt.
  • For other main control boards or higher-level main control boards (such as Arm), if you need to set the I/O port to input/output mode, you must set it to input mode/receive mode, otherwise it cannot be used. 51 series MCU can be used directly, no need to set input and output mode
  • Note: For Arduino players should set the MCU's I/O port to input mode/receive mode, otherwise it cannot be used.

5.0 out of 5 stars Excellent Price Point

The price for these is oustanding. You could not work up the resistors and other parts needed to make this work unless you could somehow put SMD parts on a tiny, little board. Even then, it would cost a bunch of moola. These are fantastic at this price point.

Used these to make a cheap PID spindle speed controller (poor man’s VFD). Works well.

4.0 out of 5 stars Visible light and an IR remote control will trigger it

The media could not be loaded.
 Just be aware that this doesn’t use any kind of coded pulses to eliminate false positives. It’s just a simple IR LED and photodiode with active low on beam break. Minus one star because ambient light can trigger it as I was hoping the photodiode was only an IR one. Use this for tinkering, but do not use it for an optical endstop on a 3d printer.
