tCam-Mini: Wireless thermal imaging camera based on ESP32

tCam-Mini is a small wireless thermal camera designed and developed by Dan Julio based on ESP32, which allows users to easily obtain and use radiation data through the Flir Lepton 3.5 sensor. It can obtain the temperature of each pixel and perform various types of thermal imaging analysis; it can also convert the data into color images to display the temperature and shape of the human body through thermal imaging.

Simple circuit to detect mobile phones

Cell phones typically send and receive signals in the frequency range 0.9 to 3GHz. This article provides a simple circuit that detects the presence of an activated mobile phone by detecting these signals.
The basic principle of the mobile phone detector circuit is to detect radio frequency signals. In Schottky diode circuits, Schottky semiconductors are used to detect mobile phone signals because of their unique properties of being able to correct low-frequency signals with low noise rates. When an inductor is placed near an RF signal source, it receives the signal through mutual inductance. This signal is rectified by a Schottky diode. This low-power signal can be amplified and used to power any indicator light, such as an LED in this case.
