Three HCSR04 scnsors have been used in the direction of front, left and right of an wooden base. we send the reading of these sensors to other arduino in each void loop, via bluetooth using HC-05 ...

So far, this has only been tested with DHT22 temperature sensors. See the .gitmodules file for the Arduino library dependencies. The following code imports the DHT logger library and creates a logger ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a temper… ...

LM35 & Memory Card This is a little DIY project with an Arduino Uno, SD card breakout board, and LM35 temperature sensor. To build a temperature logger using a microSD card, just connect the LM35 ...

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting real-time data on soil moisture, temperature, and sunlight. From sensor ...

In recent years, the monitoring systems play significant roles in our life. So, in this paper, we propose an automatic weather monitoring system that allows having dynamic and real-time climate data ...
