[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 ...

The temperature sensor is built using an NTC 10k thermistor, which changes its resistance in response to changes in temperature. The resistance of the thermistor is ...

下記の記事の続きです。前回の記事では、この取り組みの背景と温度及び湿度の計測機能の実装について書きました。この記事では、wifiモジュールによるIoTデバイス化と、MH-Z14Aによる二酸化炭素濃度計測機能の実装を行います。 Arduinoは単体で ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...
