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 ...

Getting a device on the internet is great – but what if you want to monitor multiple wireless sensors? The [WickedDevice] crew have been publishing a tutorial series focusing on just that. Their ...

[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 ...

Makers, developers and hobbyists that are looking for an easy way to connect Arduino wireless sensors to an Arduino development board, might be interested in a new system that has been created by ...

This water level and temperature monitoring system uses contact or non-contact water level sensors along with a probe-type temperature sensor. A digital display provides continuous, real-time ...

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 ...
