Small form factor IR camera capable of tracking up to four heat/IR sources, can be controlled with Arduino, AVR via I2C interface. SEN0158

The STM32W108B-SK kit provides a complete platform for learning and developing wireless applications based on STM32W108 microcontrollers. The integration of radio modules, support for ZigBee protocols, and a rich set of development tools make it a versatile solution for designers of wireless communication and IoT systems.

This breadboard-compatible module is an alternative to bulky power switches. It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 16 A at 4.5 V to 40 V. The board features reverse-voltage protection and also makes it easy to control the MOSFET with an external switch or the digital output of a microcontroller.

Universal module for building a keyboard. The set consists of a control board with a miniUSB socket and cables with crocodile clips

Module with 2 QTRX type optocoupler with RC (digital) output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 30 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4302

The DFRobot Vibration Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration. DFR0052
