Arduino Weather Station to measure temperature, pressure and humidity

This is a quick project which uses Arduino and two sensors DHT11 and BMP180 to display humidity, temperature and atmospheric pressure to on a small LCD screen. I first proofed the setup and code on Arduino Uno and then tried to shift it to a cheap Arduino Nano clone for final setup. But after facing […]

Adruino Project : Pollution Sensor System, initial setup.

Cooling for Raspberry Pi

But in places without electricity like when camping and cold weather, battery charge is an issue. I found out during my last trip to […]
