Gravity: Magnetic Latching Relay for ESP32 / Arduino
A Magnetic latching relay is a new type of relay. It features low power dissipation and noiseless. Unlike other non-latching relay, the latching relay needs two digital pulse signal to switch ON/OFF state. This DFRobot Gravity: magnetic latching relay is compatible with most...
UART Non-contact Optical Turbidity Sensor for Arduino
This non-contact turbidity sensor detects water quality by measuring the level of turbidity. Based on the optics principle, it is capable of detecting the light transmittance and scattering rate of the liquid in transparent cylinder containers with a diameter of 40–50mm, which will then be output...
Gravity: GR10-30 Gesture Sensor (UART & I2C, 12 Gestures, 0~30cm)
This GR10-30 gesture sensor is capable of recognizing 12 hand gestures: move up, down, left, right, forward, backward, rotate clockwise and counterclockwise, rotate clockwise and counterclockwise continuously, hover, and wave. And users can set parameters such as the gesture trigger distance, the...
Gravity: PAJ7620U2 Gesture Sensor
Build an awesome interactive project with this PAJ7620U2 Gesture Sensor! It is an interactive sensor with 3D gesture recognition that can recognize 13 gestures at most within 20cm. The sensor offers stable performance, fast response and high accuracy, which makes it an excellent choice for intera...
DFRobot SEN0715 Miniature Non-Contact Liquid Level Sensor
·
This compact capacitive sensor detects the presence or level of liquid through non-metallic container walls, so it does not need to touch the liquid. That helps avoid corrosion, contamination and media adhesion when monitoring aggressive liquids such as strong acids, alkalis and toxic liquids in ...
Non-contact Capacitive Liquid Level Sensor
A non-contact capacitive liquid level sensor that detects whether liquid is present inside a non-metallic container or pipe without direct contact with the fluid. It works by measuring changes in capacitance through the container wall, making it suitable for corrosive liquids, strong acids, alkal...
DFRobot SEN0676 80GHz mmWave Liquid Level Sensor - 40m UART
·
This 80GHz millimetre-wave radar module is built for precise, non-contact liquid level detection. Using Frequency Modulated Continuous Wave (FMCW) radar, it measures from above the liquid surface, making it suitable for corrosive, hazardous or high-purity liquids where contact probes are not idea...
DFRobot SEN0716 Industrial Non-Contact Liquid Level Sensor IP67
·
This industrial non-contact liquid level sensor uses capacitive sensing to detect liquid through non-metallic container walls, so it does not need to touch corrosive, viscous or contaminated liquids. It is suited to liquids such as milk, honey, latex, blood, engine oil and acid or alkaline soluti...
2.3KG Serial Bus Servo (6V)
A miniature serial bus servo from DFRobot that delivers 2.3 kg·cm of stall torque at 6 V, controllable via TTL serial communication. Up to 253 servos can be daisy-chained in series, each assigned a unique ID for individual or synchronised control at baud rates up to 1 Mbps. The hybrid gear train...
Gravity PH2.0 to Female DuPont Tagged Cable 30cm - 5 Pack
·
These labelled jumper cables are designed to make Gravity project wiring easier to follow, especially when a build has several similar connections. Each cable carries I2C/UART pin labels so you can identify power, ground, clock/receive and data/transmit lines without relying only on wire colour o...
Gravity: Water Flow Sensor (1/2) For Arduino
INTRODUCTION The Gravity Water Flow sensor measures the rate of a liquid flowing through it. The YF-S201 water flow sensor consists of a plastic valve body, flow rotor and hall effect sensor. It is usually used at the inlet end to detect the amount of flow. When liquid flows throug...
Gravity: Analog AC Current Sensor (10A)
A non-contact AC current sensor with a clamp-on transformer probe, capable of measuring 0–10 A AC. Simply clamp the probe around an AC line and connect the 3.5 mm plug to the signal conversion module — no wire cutting or circuit modification required. The Gravity analogue interface outputs a 0.2...
Gravity:TT Motor Encoders Kit
The Gravity:TT Motor Encoders Kit provides rotation tracking for TT motors, giving you accurate angular displacement data using a non-contact sensing method. Ideal for robotics projects where you need to measure wheel rotation and distance travelled. The kit uses the Gravity interface for plug-a...
