Mini PIR Motion Sensor
The AM312 sensor is a mini IR pyroelectric infrared PIR motion human body sensor that is easy to install and has low power consumption. Its digital signal processing and high sensitivity make it ideal for use in automatic sensing circuits. Additionally, the repeatable trigger mode ensures that...
Gravity: Geiger Counter Module Ionizing Radiation Detector
This Gravity Geiger Counter Module detects ionising radiation — including nuclear radiation, X-rays, and cosmic rays — using a large M4011 Geiger-Müller tube. When ionising particles pass through the tube, the module outputs a digital pulse that can be counted by any microcontroller to calculate ...
Gravity: MAX30102 Heart Rate and Oximeter Sensor
The DFRobot Gravity MAX30102 sensor module measures heart rate and blood oxygen saturation (SpO2) using photoplethysmography (PPG). It integrates the Maxim MAX30102 chip with an on-board MCU that processes raw PPG data and outputs heart rate and SpO2 values directly via I2C or UART, reducing proc...
Gravity: Arduino LPG Gas Sensor (MQ4)
INTRODUCTION This is an Arduino CH4 gas sensor. It uses MQ4 probe which is able to detect nature gas, CH4. It is less sensitivity in detecting alcohol, cooking fumes, and cigarette smoke. The sensitivity can be adjusted by the potentiometer. The output is ...
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...
Gravity: Arduino Shield for Raspberry Pi B+/2B/3B/3B+/4B
The Gravity Arduino Shield for Raspberry Pi brings Arduino-compatible I/O to your Raspberry Pi B+, 2B, 3B, 3B+, or 4B. Built around the ATmega32u4 (Arduino Leonardo), it sits on top of your Pi and gives you access to all standard Arduino shields and sensors alongside the Pi's own GPIO, I2C, SPI, ...
Gravity: I2C 16x2 Arduino LCD with RGB Backlight Display
A 16×2 character LCD module with full RGB backlight, communicating over I2C for minimal wiring. With support for 16 million backlight colours, this display adds a vibrant, customisable readout to your Arduino or compatible microcontroller projects using just four wires: VCC, GND, SDA, and SCL. P...
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: Arduino Alcohol Sensor (MQ3)
An analogue alcohol gas sensor based on the MQ-3 probe, designed for use with Arduino and other microcontrollers. The sensor outputs a voltage proportional to the concentration of alcohol vapour in the surrounding air, making it suitable for breathalyser-style projects, air quality monitoring, an...
HC-SR04 Ultrasonic Sonar Distance Sensor + 2 x 10K resistors
The HC-SR04 is an ultrasonic distance sensor that measures distances from approximately 2 cm to 400 cm (best results between 10–250 cm). Widely used in robotics, automation, interactive art, and motion sensing projects. The sensor requires 5V power and the Echo return signal is 5V logic. Two 10 ...
Gravity: LED Button x 5 Pack
A pack of five LED-illuminated push buttons in the DFRobot Gravity format. Each button lights up a different colour (red, yellow, green, blue, and white) when pressed, providing clear visual feedback. The digital output goes HIGH when pressed and LOW when released, making them simple to read with...
