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...
Gravity LED Self-Locking Switch - Red
·
This illuminated pushbutton module is a simple self-locking switch with a built-in red LED for clear visual feedback. Press it once and the module outputs High while the LED turns on; press it again and the output goes Low while the LED turns off.It is designed for easy use in Arduino, micro:bit ...
Gravity: Digital Push Button (Blue)
The Gravity Digital Push Button (Blue) is a simple momentary push button module designed for the DFRobot Gravity interface. It features an onboard LED indicator, immersion gold PCB surface, and a coloured button cap. A "D" marking on the board identifies it as a digital sensor for quick wiring re...
Buzzer Piezo 20mm
The Buzzer Piezo 20mm is a compact and efficient sound-producing device that is perfect for a variety of electronic projects. With its 20mm diameter, this piezo buzzer is designed to deliver clear and audible sound in a small form factor, making it an ideal choice for applications where space is ...
Gravity LED Button for Arduino/micro:bit - Yellow
·
This LED-illuminated button module is a simple digital switch with a transparent cap and a yellow light. It works like a basic button, but the internal LED turns on while the button is pressed, giving clear visual feedback for interactive projects.When pressed down, the module outputs High and th...
Gravity GP8600 1-Channel I2C/PWM 16-bit DAC Module
·
This GP8600 module is a high-precision digital-to-analogue converter for connecting logic-level microcontrollers to industrial-style analogue control inputs. It accepts I2C or PWM signals and converts them for applications such as 0-5V, 0-10V and 4-20mA control.It is designed for automation and c...
Gravity: Conductivity Sensor Switch
The Gravity Conductivity Sensor Switch module can be used to detect if an object has electrical conductivity. Its maximum detection value is 10MΩ. It can detect not only coins, wires, metal and other good conductors, but also the human body, fruit, plants and other conductors. By touching the...
Gravity: IIC Ozone Sensor (0-10ppm)
The Gravity IIC Ozone Sensor measures ozone (O₃) concentration from 0 to 10 ppm with 10 ppb resolution using an electrochemical sensing element. Factory-calibrated for accurate readings out of the box, it connects via I2C through DFRobot's Gravity 4-pin interface. Compatible with Arduino, ESP32,...
ESP32-S3 AI Camera Module (Edge Image Recognition, Night Vision, ChatGPT Voice Interaction)
·
An intelligent AI camera module built around the ESP32-S3 chip, combining a 160° wide-angle infrared camera, onboard microphone, speaker, and powerful edge AI capabilities. Designed for video processing, image recognition, and voice interaction — all in a compact 42 × 42mm form factor. The modul...
Gravity Flexible Non-Contact Capacitive Liquid Level Sensor
·
This flexible capacitive liquid level sensor detects liquid through the wall of a non-conductive container, so it does not need to touch the liquid itself. It is designed for containers with a wall thickness of less than 5 mm, making it handy for sealed tanks, pipes and other setups where a conta...
Hall-Effect Sensor - AH1815 (Non-Latching)
The AH1815 is an integrated Hall-Effect non-latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A...
Gravity: I2C VEML7700 Ambient Light Sensor (0~120Klx)
The Gravity VEML7700 is a high-accuracy digital ambient light sensor that outputs readings directly in lux (lx) over an I²C interface. Built around the Vishay VEML7700 IC, it features a 16-bit ADC, a high-sensitivity photodiode, and a low-noise amplifier — delivering precise light measurements wi...
Ceramic Resonator 16MHz
Resonators function like crystals, but are a lower cost solution that does not require external caps.These resonators are +/-0.5% or better from -20C-+80C. These resonators have built-in load capacitors so no external caps are needed.
