Arduino Sensors and Modules

About this deal

Arduino sensors and modules are individual electronic components designed to let an Arduino microcontroller interact with the physical world. They detect changes in physical conditions such as temperature, movement, light, or sound , and a module is a pre-manufactured circuit board that includes one or more sensors alongside supporting components such as resistors, capacitors, and transistors, making it straightforward to interface with an Arduino board. Most are supplied in a module form-factor, meaning they already include things like current-limiting resistors, terminal posts, and potentiometers on-board to help save time. Popular types include temperature sensors such as the DHT11, humidity sensors, light sensors, ultrasonic distance sensors, and PIR motion sensors. They are used across a wide range of applications including robotics, environmental monitoring, and home automation. These components suit hobbyists, students, and makers at all levels, and many are compatible with Arduino Uno boards as well as Raspberry Pi and other platforms.
