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
The MPU9250 is a 9-axis inertial measurement unit (IMU) that combines a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer in a single compact package.

This makes the MPU9250 ideal for applications that require … Read more
The PMS5003 is a digital particulate matter sensor that uses laser scattering technology to measure the concentration of airborne particles in three size categories: PM1.0, PM2.5, and PM10. It provides calibrated mass concentration data as well as raw particle counts through a UART interface, making it easy to integrate with microcontrollers and single-board computers. The … Read more
The MQ5 is an analog gas sensor designed to detect flammable gases such as LPG, natural gas, and town gas by measuring changes in the resistance of a heated sensing element. It provides both an analog output proportional to gas concentration and a digital output that can be triggered at a user-defined threshold. The sensor … Read more
The MPU6050 is a 6-axis inertial measurement unit (IMU) that combines a 3-axis gyroscope and a 3-axis accelerometer in a single compact chip. It is widely used in drones, self-balancing robots, motion-tracking systems, gaming controllers, and gesture-recognition devices. By measuring both acceleration and rotational movement, the MPU6050 can determine an object’s orientation, tilt, and motion … Read more
The MQ135 is an analog air quality sensor by Winsen Electronics that detects a broad range of toxic and pollutant gases by measuring resistance changes across a heated tin dioxide element. Unlike the rest of the MQ series (which each target one or two specific gases), the MQ135 is designed as a general-purpose air quality … Read more
The MQ7 is an analog carbon monoxide (CO) gas sensor that detects the presence of carbon monoxide in the air by measuring changes in electrical resistance. Carbon monoxide is a colorless, odorless, and highly toxic gas produced by the incomplete combustion of fuels such as gasoline, natural gas, coal, and wood, making it impossible to … Read more
