## Customer Reviews

### ⭐ Does not work
*by J***  on 1 October 2023*

It does not work . All things are connected properly .but still sensor fails to work

### ⭐⭐⭐⭐⭐ Replacement sensor working perfectly.
*by M***R on 13 May 2021*

The media could not be loaded. First Sensor was defective. It did not work. I scheduled a return. Allianztec sent me another sensor. This sensor module was already soldered. I connected the sensor and worked perfectly. Really appreciate Allianztec for providing a working replacement sensor. One suggestion for Allianztec - It would be great to provide an option for soldered and unsoldered module selection.

### ⭐ There is a problem with hardware
*by K***A on 4 September 2021*

Dear seller I think you should avoid sellinhlg this item as there is a hardware problem with the sensor (3 pull up resistors are connected to 1.8v instead of 3.3 volt) and because of this hardware problem this sensor is not working with the micro controllers like arduino. I have seen a lot of people complaining about the sensor not working, the problem might be bcz of this.Thanks
