In this module we will wire up an ultrasonic sensor and attach it to our Raspberry Pi. Using the ultrasonic sensor we will measure the distance an object is away from the sensor. The distance of the ...

This module uses an ultrasonic sensor to trigger certain notes to be played through the pi. An object is held in front of the sensor and moved either closer or further away to make music. This is ...

Raspberry Pis and Home Assistant are a match made in heaven. The former is great at sensing the world around it and collecting data, and the latter is amazing at taking in data, making decisions, and ...

PCWorld explains how to create an affordable CO2 air quality monitor using a Raspberry Pi and MH-Z19C sensor for under $40. This DIY project helps monitor indoor air quality since high CO2 levels ...

More often than not, an IoT master device uses the SPI (serial peripheral interface) and I 2 C (inter-integrated circuit) protocols to exchange data with EEPROMs or sensors that are operating in slave ...

I2C makes connecting multiple sensors to a Raspberry Pi straightforward by sharing just two pins for communication. With proper setup, scanning, and coding, you can integrate dozens of devices on a ...
