The above link is the apk application link that is needs to be installed in you phone.

Whereas, the GitHub link is the source file of the application written in Java and kotlin, that is not required for your phn but it is required for those who want to develop or want to change the application as per there needs.

Download the apk and install it.
1. Make sure you are downloading as .apk file.
2. Your phone is allready configured to install third party applications out of the play Store.

Reference to the project I have made circuit.

I have upload the programme on Arduino nano.

In serial Monitor it prints:- as given below:-

Noise + Signal = 514
Noise =512
--> Signal =-2
31.4
position_error
Noise + Signal = 490
Noise =489
--> Signal =-1
31.4
position_error
Noise + Signal = 474
Noise =473
--> Signal =-1
31.4
position_error

I have tried with keeping my hand near the same.

It gives the resuls  and print temperature changes , but also print: position_error.

--> Signal =-1
32.4                        hand away results
position_error
Noise + Signal = 361
Noise =361
--> Signal =0
33.6                        hand away results
position_error
Noise + Signal = 361
Noise =361
--> Signal =0
35.2                        hand near results
position_error
Noise + Signal = 361
Noise =360
--> Signal =-1
36.0                        hand near results

Also connected with OTG cables on my mobile.
