Interfacing HC-SR501 PIR Motion Sensor with Raspberry Pi

Contents 1 Working of PIR sensor HC-SR501 1.1 Adjustment 2 Circuit diagram 3 Python Program 4 Output All living beings radiate energy to the surroundings in the form of infrared radiations which are invisible to human eyes. A PIR (Passive infrared) sensor can be used to detect these passive radiations. When an object (human or animal) emitting infrared radiations passes through

How to Generate a High-Precision Waveform Using a DAC and a Custom PCB

In this article, we’ll develop firmware that will serve as the basis for high-precision, high-speed signal generation. I recently designed an arbitrary waveform generator (AWG) PCB that is built around a C8051F360microcontroller and a TxDAC from Analog Devices. These two ICs communicate via a parallel interface that allows me to generate higher-frequency analog signals by seeking
