DFRobot Gravity 10DOF IMU AHRS (BNO055 + BMP280)
·
This compact Gravity module combines a Bosch BNO055 absolute orientation sensor with a BMP280 barometric pressure and temperature sensor to create a 10DOF AHRS module for motion, heading and environmental sensing.The BNO055 integrates a triaxial 14-bit accelerometer, triaxial 16-bit gyroscope, tr...
Gravity: Arduino CO2 Gas Sensor
The Gravity CO2 Gas Sensor uses an MG-811 electrochemical sensing element to detect carbon dioxide concentration in the air. The output voltage decreases as CO2 concentration increases, and an onboard potentiometer lets you set a threshold for a digital on/off signal output. An onboard heating c...
MLX90640 32x24 IR Array Sensor - 55° FOV
·
The MLX90640 is a fully calibrated thermal IR array sensor with 32x24 pixels, giving you 768 FIR pixels for non-contact temperature sensing. It uses a digital I2C interface and comes in an industry standard 4-lead TO39 package.An ambient sensor is integrated to measure the chip temperature, along...
Gravity: Arduino Propane Gas Sensor (MQ6)
INTRODUCTION This is an Arduino Propane Gas Sensor. It uses MQ6 probe to detect iso-butane, propane and liquefied petroleum gas (LPG). It is less sensitive with alcohol, cooking fumes and cigarette smoke. It can be used in gas leakage detecting equipment in...
Gravity: I2C LCD1602 Arduino LCD Display Module (Green)
A 16×2 character LCD display module from DFRobot's Gravity series, connecting to your Arduino or microcontroller via a simple I²C interface — just two data wires instead of the many parallel connections a standard LCD1602 requires. Compatible with both 3.3V and 5V, with no contrast adjustment nee...
Gravity: Alcohol Sensor (0-5ppm)
This is an Arduino compatible alcohol sensor module from DFRobot with a 0-5ppm measuring range, supporting I2C and UART outputs. Aiming at fast and accurate detection of alcohol gas concentration in the air, the sensor is well applicable to the small alcohol concentration measurement in...
Mini Photocell
This type of photoresistor is made of environment-friendly materials(no Cadmium and Lead) compared with the traditional CDS photoresistor. It changes resistance depending on the amount of light it is exposed to. These little sensors can be used in light-interacting projects. SPECIFICATIONS Head ...
Gravity: I2C LCD1602 Arduino LCD Display Module (Gray)
The Gravity I2C LCD1602 is a 16×2 character LCD display module from DFRobot's Gravity series, redesigned with a clean modern look and simplified I2C interface. It eliminates the need for contrast adjustment, retains backlight control, and is compatible with both 3.3 V and 5 V systems — making it ...
Gravity: I2C 16x2 Arduino LCD with RGB Font Display (Black)
The Gravity I2C 16×2 LCD features RGB font colours on a black background, allowing you to display text in any of 16 million colour combinations. Using the Gravity I2C interface, only two data lines are needed for both communication and backlight control. The display supports 2 rows of 16 charact...
