I read about applications like tawkon and too close recently. I am aware that they keep a watch to the mobile's radiation level and do something when the radiation level mounts. I am impressed with those apps. I wanna learn about how they work and I wish to code a simple app that keeps track of my phone's radiation level.
I thought that the TYPE_MAGNETIC_FIELD sensor would be able to find the radiation emission. When I browsed, I came to know that it is a sensor to measure the ambient geomagnetic field i.e; the magnetic field immediately surrounding the device.
I suspect that the radiations emitted out of the mobile phone must be largely responsible for the surrounding magnetic field. If what I think is right, I hope that I must be proceeding with the TYPE_MAGNETIC_FIELD sensor.
Please let me know, if I am right. If not, please guide me to the correct sensor that can achieve my own tawkon kinda.
