SGP30 Digital Gas Sensor The SGP30 is a digital gas sensor from Sensirion designed to detect various gases in the ambient environment. It is commonly used to measure the concentration of Total Volatile Organic Compounds (TVOC) and equivalent carbon dioxide (eCO₂) in the air. TVOC (Total Volatile Organic Compounds) TVOC is a measure of the […]
APDS9960 Gesture Sensor The APDS9960 is a digital RGB (Red, Green, Blue) and gesture sensor manufactured by Broadcom, now part of Avago Technologies. This sensor is designed to detect hand gestures, proximity, and ambient light, making it useful for applications such as touchless gesture-controlled interfaces in electronic devices. It operates by emitting infrared light and […]
A rotary encoder is an electromechanical device used to convert the angular position or rotation of an object into an electrical signal. It’s commonly used in various applications, such as measuring the position of knobs on electronic devices, controlling the movement of motors and machinery, or even in computer mice. Rotary encoders can be of […]
The DS3231 is a popular real-time-clock (RTC) integrated circuit (IC) manufactured by Maxim Integrated. An RTC is a device that keeps track of time even when the main power source to a system, such as a microcontroller or a computer, is turned off or unavailable. The DS3231 is commonly used in a variety of electronic […]
The MPU6050 is a sensor module used in electronics and robotics. It combines a 3-axis accelerometer and a 3-axis gyroscope in a single package. This combination of sensors allows it to measure both linear motion (acceleration) and rotational motion (angular velocity) in three dimensions each. It is commonly used in projects involving motion tracking, orientation […]
