The product is correct, is very simple to use. And is very CHEAP No manual attached, but the signals are indicated over the pcb very usefull with arduino uno R3. The device engages well with the arduino heads. The pinout is compatible. I probe with blinkink a led with the signal for the sensor is activated and the system worked well. It's perfect for ...

Might be very nice for a home project with your arduino board. The quality is really nice, for the price I couldn't imagine such a nice product. If you need it, buy it. Couldn't find many usefulness, maybe when I have many projects I can tell, but till now I think it is not that useful. But it was cheap and it's here, if I need I use. Might be nice ... Read more
This module is really easy to use, it is well made and the board is tiny enough to use it in a lot of applications. Range voltage of 3 to 6v allows this module to be connected in a wide range of projects. It has an enable input that can be controlled by a uC in order to reduce power consumption when it is not being used. The led indicating a detection ... Read more
pulses IR LED for best sensitivity to IR detector. Very nice design, simple to use. no documentation. you must experiment to figure out how to use. The circuit uses a 555 timer chip to pulse IR LED, which is detected by IR detector. Use 2K pot to tune 555 frequency for best sensitivity by IR detector (around 38khz). Also, the IR detector can pick up ... Read more
-Pequeño modulo sensor infrarojo.
-Es de salida digital, recomendado usar con resistor pull-up
'desde arduino, es un juego de niños manejarlo -El unico detalle es la distancia de sensado, aprox 20 cm max. el potenciometro adjunto no regula demasiado. ...Cuando la version analoga ? tipo hc-sr04 pero infrarojo. ...buen sensor para ... Read more
easy to mount
very clean pcb layout
IR led shielded on the sides to avoid interference
enable option and enable jumper
very good to interface with a micro controller
Looks just like the image advertised. Very small and compact. Easy to use, header pins just slide into breadboard. Pot variations are not precise at all, they either sens or ... Read more
Really small, it will fit into every DIY project.
Really good price (don't bother soldering your own, it is better to buy one)
Detection LED on board (it will show you when it is working)
Range tuning available (two variable resistors on board)
Short range (which is a pro for me) No manual attached (you will have to check how it is working for yourself)... Read more
Easy to use, although no instruction manual, compact and inexpensive. Recommended. Fácil de usar, embora não tenha manual de instrução, compacto e barato. Recomendado. Does not come with instruction manual. But nothing about 2 minutes and a multimeter can not solve. And mention 40cm however, adjusting the pot, I got around 30cm. ... Read more
- potentiometers allow range tuning
- very small packaging
- hole for bolt
- on board LED to show detection ( you can disable this feature using a strap on the board) - need reverse engineering to understand how its work ( no user manual)
- limited range as foreseen and mentioned. 30 cm is the max range i have reached. - doesn't work on black objects ... Read more
