In the land of electronics, there are many different types of sensors.
If you start dabbling in electronics, it won’t be long before you end up needing/wanting to measure some sort of quantity like temperature, speed, light level, distance, sound, humidity etc.
This is especially true if you work with Arduino, RPi, PICs, or any sort of platform or microcontroller.
These days, there are many different electronic sensors to choose from. Given the pace at which technology advances and the myriad of sensors available, those new to electronics often find themselves confused about sensors and how to apply them.
What type of sensors do I need? How do I use this particular sensor?
The above are common questions hobbyists often ask themselves.
