MQ-135 Gas Sensor

Optical liquid level sensor module with switching function with NPN output.

The ACS72981 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 250 kHz) and low conduction resistance (0.2 mΩ), it minimizes energy loss and offers a fast response time of less than 2 µs. Pololu 5263

Temperature sensor based on a DS18B20 chip replacement. It is enclosed in a waterproof measuring probe. It has a 2 m cable and communicates via a 1-Wire interface

360-degree laser scanner (LIDAR), with a range of up to 12 meters and measurement frequency up to 10 Hz (optimal value 5.5 Hz). DFRobot DFR0315

A modern module that enables gesture control and detects the presence of people, ensuring privacy and fast offline interactions. Equipped with a camera and an AI processor, the sensor recognizes 5 hand gestures and detects up to 10 faces within a range of 3 meters, supporting I2C and UART communication, making it an ideal solution for IoT, smart homes and touchless systems. DFRobot SEN0626

A modern current sensor combining the Hall effect with an inductive coil, which allows for precise measurements of both the DC and AC components up to 5 MHz. Thanks to its lightning-fast response time and low path resistance, it is perfect for motor control systems, power converters and protection systems. Pololu 5230

Pololu Carrier with Sharp GP2Y0D810Z0F Digital Distance Sensor 10cm

Pololu Carrier for Sharp GP2Y0D810Z0F and GP2Y0D805Z0F Sensors

A module with line sensors designed to work with the Kitronik kit. It has two sensors in the form of phototransistors that generate an analog voltage that can be read by the microcontroller. The module is equipped with a 4-pin connector (3V, 0V, L, R), which allows for power supply and reception of signals from the sensors, and the output voltage changes depending on the detected surface, which allows it to be used not only with the Kitronik kit, but also with platforms such as Arduino or Raspberry Pi Pico.
