Waveshare Photo Interrupter Sensor is an IR optical sensor module with Schmitt trigger and a signaling diode allowing the construction of an incremental encoder. Waveshare Photo Interrupter Sensor

Laser radar based on cwToF technology and metasurface lenses, offering depth maps and IR images in 160x60 pixel resolution and a wide viewing angle of 108°x40°. Thanks to its solid-state construction, range up to 4.5 m and resistance to strong lighting (up to 60 Klux), it is ideal for applications such as robotics, obstacle avoidance systems, access control and volume measurement. DFRobot DFR1177

Precise Hall effect sensor that converts magnetic field intensity into analog voltage. Differential response to magnetic poles (voltage increases when approaching S pole and decreases at N pole) enables precise analysis of field direction and strength. High sensitivity, low noise and compatibility with platforms such as Arduino and micro:bit make the sensor ideal for industrial, educational and hobby applications. DFRobot DFR1132

The Gravity Occupancy Sensor uses 24 GHz FMCW radar technology, enabling precise presence detection at a distance of up to 8 meters and movement and distance measurement up to 12 meters. Thanks to its high resistance to environmental interference, it works reliably regardless of light, temperature or dust, effectively detecting both static and dynamic objects. Compatibility with Arduino, ESP32, Raspberry Pi and a simple Gravity interface make it an ideal solution for intelligent lighting, building automation and security systems. DFRobot SEN0610
