Through it, you can control a circuit of high voltage with low voltage, say 5V on the controller. There is an indicator LED on the board, which will light up when the controlled terminals get closed.

This module can be used to measure temperature, atmospheric pressure and humidity accurately and fast. As the atmospheric pressure changes with altitude, it can also measure approximate altitude of...

A 4 digit display module usually uses 12 pins. In this Grove gadget the TM1637 is used to scale down the control pins into two Grove pins. This way It only takes two digital pins from an Arduino to...

This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low...

Grove - Servo is used in driving mechanism of robots. The module is a bonus product for Grove lovers. We regulated the three-wire servo into a Grove standard connector. You can plug and play it as ...

It can detect combustible Carbon Monoxide, Coal Gas and Liquefied Gas. The sensitivity can be adjusted by the potentiometer. Hardware Overview This is an Analog output sensor. It needs to be conn...

The module consists of an IR LED and a photosensor (phototransistor) pair. The light emitted by the IR LED gets reflected by any object placed in front of the sensor and this reflection is detected...

Provide reliable data for air purifier system Easy maintenance PWM output Grove compatible interface Compact and light design. This Dust Sensor gives a good indication of the air quality in an env...

Grove - RGB LED Stick (15-WS2813 Mini) is a cost-effective full color LED stick with 15 chainable and programmable WS2813 mini LEDs. This Grove - RGB LED stick is similar to Grove - RGB LED stic...

Most of automated robotic projects start from a line-following robot, Grove - Line finder v1.1, designed to achieve this task easily and quickly. Those eye-like sensors on the board are actually IR...

USB 2.0 Type A Male to Micro Type B Male Cable Black - 1 m This cable is needed to connect your PC to a board that uses this kind of connector.

It has a low power consumption digital chip LSM6DS3 and power supply regulator which features high sensitivity and low noise interference. It can be configured to different levels of sensitivity to...

The X and Y axes are two ~10k potentiometers which control 2D movement by generating analog signals. The joystick also has a push button that could be used for special applications. When the module...

Universal 4 Pin Buckled Cable is made for the Grove System to connect all of the Grove modules to the Basic Shield or to other Grove compatible boards for quick prototyping. 30 cm cables

The resistance of a thermistor will increase when the ambient temperature decreases. It’s this characteristic that we use to calculate the ambient temperature. The detectable range of this sensor i...

The sensor(chip) used in the module is designed with Sensirion’s CMOSens® technology. The chip is well calibrated, linearized and compensated for digital output. The typical accuracy of this module...

This shield pulls out the pins of the motherboard and expands to 8 Grove connectors, including 3 Grove digital connectors, 3 Grove analog connectors, 1 Grove I2C connector, and 1 Grove UART connect...

This is a small breadboard (4,6x3,6 cm) with 170 tie points. It is self-adhesive and compatible with the Arduino Proto Shield.
