Current Sensor – how to build it yourself

In this article I show how you can build a shunt-based current sensor like the INA219 or INA226 yourself. I present two solutions.

ADS1115 – A/D converter with amplifier

The ADS1115 is a 16-bit, 4-channel A/D converter with amplifier and alert function. I explain its technical details and present my associated library.

INA226 Current and Power Sensor

The INA226 is a current and power sensor which, in contrast to the INA219, is equipped with an alarm pin for limit violations. I present the INA226 module and my associated library.

INA219 Current and Power Sensor

With the INA219 module, you can measure currents and power conveniently and reliably. I explain how this works and introduce my library INA219_WE.

HX711 based balance

With an HX711 module and a load cell, you can easily build an astonishingly precise balance. I also show you how to install an automatic shut-off system.

Hall Sensors and Reed Switches

Hall sensors and reed switches are electrical components that respond to magnetic fields. I show which variants there are and how to use them.

IR proximity sensor – how to build it yourself

In this article I show how to build an IR proximity sensor yourself. I present two approaches, one with pulsed signals and one without.

Sensor comparison – ambient light, proximity, motion

This is the conclusion of my series on distance, proximity, motion, ambient light, gesture and color sensors. I will compare the functions of the different sensors.

SI1145 ALS, IR, UV and PS sensor

I present my library for the SI1145 module. The essential functions of the SI1145 have been implemented. Example sketches are explained in detail.

UV sensors and sensor modules

In this post I present the most common UV sensors for Arduino and Co., how they determine the UV index and I will talk about the limitations.
