8/20/2023 0 Comments Rpi arduino sensors![]() Arduinos and their derivatives come in a large variety of sizes and capabilities from a variety of vendors. Unlike Raspberry Pi, Arduinos and microcontrollers do not have a full operating system instead, their firmware interprets and runs whatever code they were programmed with without the overhead of an operating system. Your refrigerator, toaster, and TV remote may each have a microcontroller inside managing their respective jobs. A microcontroller is a small computer on a single chip that is used for relatively simple tasks. It came into being to teach kids programming and to provide them with a general understanding of how computers work.Īrduino, on the other hand, is a family of microcontroller boards that generally have only two ports: one for power and one for programming. It has most of the same ports as a modern desktop computer and can be easily connected to a monitor, keyboard, Ethernet, etc. Raspberry Pi is basically a credit card-sized PC that runs a Linux-based operating system. Both are roughly the same size.Īrduino and Raspberry Pi are very different animals. A Raspberry Pi with its many ports (left) alongside a basic Arduino Uno (right). Included in this are those interested in environmental sensing, primarily for citizen science applications.įigure 1. The purchase of parts creates a supporting economy in hardware, and the contributions of individuals in creating open-source software and hardware continually lowers barriers to entry in terms of the skills and knowledge needed for new people. A ‘maker culture’ has developed (analogous to hacker culture) where people not formally trained in electronics build and tinker with their own electronics and robotics. They are relatively inexpensive, generally $20-$30, and are much easier for non-engineers to work with than the electronics and computers of decades past. Since I began working for the North Temperate Lakes (NTL) LTER site in 2014, I have heard a lot of people express interest in the possibility of building their own environmental sensors using Arduino or Raspberry Pi as the computing core.
