The last chapter looked at some inputs and outputs using Python GPIO Zero. This chapter will look at working with some more sensors and outputs. Some of these can be used with the GPIO Zero module and others use other Python libraries. These include detecting people entering a room, sending and receiving infrared signals, and displaying output on an LCD display.

PIR Sensor and Pi Camera

In this project, you will learn how to use a PIR (passive infrared) sensor to detect someone entering a room and take a photo of people as they enter. This could be useful ...
