Sensors are the sensory organs of any electronics project, converting physical phenomena — light, temperature, motion, distance, pressure, sound, and more — into electrical signals that a microcontroller can read and act upon. The right sensor is the starting point for any data-driven or reactive build.

This collection spans the complete sensor range stocked at Kuriosity: environmental sensors for temperature, humidity, air quality, and gas detection; motion and position sensors including accelerometers, gyroscopes, and PIR detectors; distance and proximity sensors; biometric sensors; flow and water level sensors; and force and weight sensors.

Sensors from this range are used across every category of maker and engineering project in Singapore: IoT environmental monitoring, smart home automation, Arduino and Raspberry Pi STEM education kits, robotics, industrial condition monitoring, wearable health devices, and scientific data collection.
