The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

電子工作初心者がArduinoを使ってwifi環境センサを作ってみたので、その体験を書きます。Arduinoとは、家電の制御にも使われている小さいコンピュータ、通称マイコンの一種です。こいつを使ってデバイスを自作することができます。 モチベーション ある日 ...

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 ...

This library is not tested with hardware yet. (it is based upon datasheet + app note). If you have hardware and can test with SPI, please let me know (open an issue). The BL0940 is a configurable ...

This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...
