The distance on this sensor is great for small projects, about 4 meters, very small, it doesn’t take up a lot of space. I havent had any issues with any of the ones I’ve ordered.

unfortunately i have no luck with this item.
1. it will not work on 3,3V. On 5v it’s working.
2 it is not reliable.
A further investigation told me that when it’s dark, the sensor activates by itself en not reliable . when its light its working well.
I tried several test in dark boxes and this is the result.
It’s a pity because is very small en easy to use.

this module is very sensitive to DC power noise. using an AC offline DC switching module to convert 120VAC to 5V with ESP8266 module, this module will constantly false trigger. I helps to use pi filter with 10mH and two 470uF, then filter false triggers in software. They are handy, but beware of glitches.
