Motor current detection system solution based on ADSP-CM408 and AD7403

For small and medium power motor applications, the EPSH-MPC development platform provides current sampling of the isolated analog-to-digital converter AD7403. The external current loop is converted into a corresponding shunt voltage through a shunt resistor and input to the voltage test terminal of the AD7403. The AD7403 outputs according to the clock signal given by CM408F. ADC bit stream, CM408F enables the built-in SINC filter on the input bit stream to calculate the corresponding 16-bit ADC value, and stores the data into the corresponding ring queue through DMA. The host computer software can use the UART-USB port Or obtain the display of data samples through the RS485 port, you can intuitively see the acquisition effect of AD7403, and the collected data can be stored in an excel table to facilitate corresponding analysis of the data.

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.
