    The sensor works fine. Finding the wiring Schema was a pain. 1 White goes to 5V 2 blue connect via resistor (220R) to 5V 3 yellow is Signal (Pull down via 4k7 resistor) 4 red is GND It would be much more according to standard if Red would be 5V white 5V via resistor blue GND and Yellow Signal ... especially having red as ground is strange ...

    low cost product but I need to ask again and again about wiring/connection to customer service. Why not all info available on product info page?

    This sensor seems to be well made. It does not come with specs, so it is not clear how the cables are connected. It would be much better if, at least on the website, the colours of the cables would be assigned.

    Excellent product Works perfectly. I am using it to get mail/phone call through IFTTT on sensing by using ESP8266.

    The item is for contact measurement, it has to be placed inside tank. If you want contactless measurement look for something else. Otherwise it works as described. The sensor head has to be in constant with liquid.

    Optical Liquid Level sensor. Ideal for most projects, far superior to a standard reed switch float switch.
