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