TVOC and eCO2 Sensors

Using the CCS811 and SGP30 as examples, I explain how metal oxide-based TVOC and eCO2 sensors work, how to drive them with libraries, and how reliable they are compared to NDIR CO2 sensors.

MH-Z14 and MH-Z19 CO2 Sensors

With CO2 sensors of the MH-Z14 and MH-Z19 series you can monitor the indoor air quality. I show how you how to control the sensors and I check their accuracy.

MPU9250 – 9-Axis Sensor Module – Part 2

This is part 2 of my article about the 9-axis sensor MPU9250 and my related library MPU9250_WE. I will explain how to measure angles and how to use interrupts, the cycle mode and FIFO.

MPU9250 – 9-Axis Sensor Module – Part 1

The MPU9250 is an accelerometer, gyroscope, magnetometer and thermometer. I present its technical characteristics and give an introduction to my library.

ADXL345 – The Universal Accelerometer – Part 2

In the second part of my article about the ADXL345 and my library I go into Activity/Inactivity, Single and Double Taps and FIFO.

ADXL345 – The Universal Accelerometer – Part 1

The ADXL345 is a 3-axis accelerometer with many features. I explain how to use it with my associated library.

MMA7361 – Analog Accelerometer

I show you how to use the analog 3-axis accelerometer MMA7361 to determine acceleration, angle and orientation and how to use the free fall interrupt.

MPU6050 Accelerometer and Gyroscope

The MPU6050 is a 6-axis gyroscope and accelerometer. I show you how to control it with and without a library and use its interrupt function.

This is my last (!) post about current sensors. The INA282 determines currents by amplifying the voltage dropping across an external shunt. The output value is analog. I show you how to use the INA282 with the Arduino UNO or other microcontrollers.

MAX471 Current Sensor

This my the penultimate article on the subject of current sensors. This time it is about the MAX471, a shunt-based current sensor with internal amplifier. I present two modules and show how to use them on the Arduino.
