KnowFlow Basic Water Monitoring Kit
·
Build a DIY water quality monitor for field studies, teaching or environmental projects with the KnowFlow Basic Kit. This Arduino-based kit measures two key water parameters: pH and electrical conductivity (EC).Data can be recorded automatically to a micro-SD card for later analysis, and the Blun...
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: 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: Speech Synthesis Module(Support English and Chinese)
The Gravity Speech Synthesis Module converts text to spoken audio in English and Chinese, including mixed-language content. It connects via I2C or UART using the standard Gravity interface and includes a built-in speaker, so no additional audio hardware is needed. The module supports text contro...
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 ...
LPS331AP Pressure/Altitude Sensor Carrier with Voltage Regulator
A breakout board for ST's LPS331AP digital barometric pressure sensor. This sensor measures absolute pressure from 260 to 1260 mbar with excellent accuracy (±2 mbar), making it ideal for altitude estimation, weather monitoring, and indoor navigation applications. The board includes an onboard 3....

The Hackster and DFRobot EEDU Environmental Sensor Kit provides everything you need to get started with IoT environmental monitoring using an ESP32-based FireBeetle board. Build practical projects that monitor soil moisture, air quality, and environmental conditions in real time. The kit centres...
Gravity: I2C HUB
This Gravity: I2C HUB module is designed to connect up to 8 I2C devices to a main-controller, which allows you easily to hook up multiple I2C devices in project building, for instance, use Gravity-4P I2C/UART sensor cable to connect with Gravity modules or use Jumper Wire to c...
VL53L1X Time of Flight (ToF) Sensor Breakout
The VL53L1X Time of Flight sensor breakout uses a low-power laser to measure distances with excellent accuracy and speed. With a detection range of 4 cm to 4 metres and up to 50 Hz sampling frequency, it's ideal for proximity sensing, presence detection, and collision avoidance on robots. This b...
Gravity: Throw-in Type Liquid Level Transmitter
This throw-in type liquid level transmitter adopts high-performance pressure sensing chip, with advanced circuit processing and temperature compensation technology. The level transmitter receives different pressures at different depths of liquid, which can be converted into corresponding current ...
DS3231 High Precision RTC Clock Module for Raspberry Pi B+
A high-precision real-time clock (RTC) module based on the DS3231 IC, designed to plug directly into a Raspberry Pi B+ (and compatible with Arduino). The DS3231 maintains accurate timekeeping with ±5 ppm accuracy (±0.432 seconds per day) across −40 °C to +85 °C, and includes a coin cell battery b...
FlexiForce Pressure Sensor - 100lbs.
This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. Pressing hard, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pr...
Flex Sensor 4.5
A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. It’s so bad! The resistance of the flex se...
Flex Sensor 2.2
A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. It's so bad! The resistance of the flex s...
