Current cost to run ordinary website (like, a less visited personal … [Read more...]
ESP32 With DHT11 Deep Sleep : Part 1
Here is part of ESP32 with DHT11 deep sleep guide explaining the basic behind code. Our DOIT ESP32 board (which we commonly use in examples on this website), not energy efficient for deep sleep. However, it works. We already can connect normal Arduino UNO with DHT 11, with ESP32 Arduino and also we can use the setup to send data to IBM Watson IoT. ESP32 offers us deep sleep mode for power … [Read more...]

What is Infrasound? How Human Reacts to Sub 20Hz Infrasound?
Sub 20Hz sounds are infrasound and commonly we need special electrical system to pick up the sounds of that range. Infrasounds are low frequency sound waves. They are both mechanical vibrations and acoustic oscillations. They are usually below the threshold of sounds perceptible to the human ear (between 0 Hz and 16 to 20 Hz approximately) At lower frequencies, for physiological reasons, they are … [Read more...]
