The VEML6070 is a single-chip UVA light sensor designed using a CMOS process. It incorporates a UV-sensitive photodiode, internal amplifier stages, a low-pass filter, a temperature sensor for compensation, an oscillator, a timing controller, and an I²C output buffer — all inside a compact 6-pin OPLGA package measuring 2.35 × 1.8 × 1mm. Unlike some … Read more

The TCS34725 is a color light-to-digital converter manufactured by ams (formerly TAOS — Texas Advanced Optoelectronic Solutions). It contains four photodiode channels — red, green, blue, and clear — each with its own dedicated 16-bit integrating ADC that converts the detected light intensity directly into a digital value. The clear channel measures total unfiltered light … Read more

The TCS3200 is a programmable color light-to-frequency converter that detects the color of an object by measuring the intensity of red, green, and blue light reflected from its surface. By selecting different onboard photodiode filters and reading the resulting output frequency, it can identify a nearly limitless range of visible colors and deliver the result … Read more

The JSN-SR04T is a waterproof ultrasonic distance measurement module that detects the range to an object by timing how long it takes an ultrasonic pulse to travel out, reflect off a surface, and return. Unlike standard ultrasonic modules, its sensing transducer is sealed and mounted on a cable separate from the control board, allowing the … Read more

The AM312 is an ultra-miniature passive infrared (PIR) motion sensor module that detects movement by sensing changes in infrared radiation emitted by warm bodies passing within its field of view. Unlike larger PIR modules, the AM312 packs all its sensing and processing electronics directly into the sensor housing itself, producing a simple digital output with … Read more

The HC-SR04 is a low-cost ultrasonic distance sensor module that measures distance to an object by emitting a burst of ultrasonic sound waves and timing how long it takes for the echo to return. By using the known speed of sound, the time delay between transmission and reception is converted into an accurate non-contact distance … Read more

The ICM-20948 is a 9-axis motion-tracking IMU that combines a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer in a single compact package, alongside an onboard Digital Motion Processor (DMP) for sensor fusion. By measuring rotational movement, acceleration, and magnetic field direction, it provides accurate motion tracking, orientation sensing, and heading information at extremely … Read more

The BNO055 is an intelligent 9-axis absolute orientation sensor that combines a triaxial accelerometer, gyroscope, and magnetometer with an onboard 32-bit microcontroller running dedicated sensor fusion firmware, all inside a single package. By processing all three sensor inputs internally, it outputs ready-to-use orientation data directly, with no fusion algorithm required on the host side. This … Read more

The HC-SR501 is a low-cost passive infrared (PIR) motion sensor module that detects movement by sensing changes in infrared radiation emitted by warm bodies, such as humans and animals, passing within its field of view. By comparing infrared levels over time, it can provide a simple digital HIGH/LOW output whenever motion is detected. This makes … Read more

The GP2Y1010AU0F is a compact optical dust sensor manufactured by Sharp that combines an infrared emitting diode and a phototransistor in a single plastic housing. By detecting the intensity of light scattered by airborne particles, it can provide a real-time analog voltage output proportional to dust concentration in the surrounding air. This makes the GP2Y1010AU0F … Read more
