There is a continuous-time switch on this Grove module. The output from the module switches from low (turns on) when a magnetic field (south polarity) is perpendicular to the Hall sensor and when it passes the operate point threshold BOP it switches to high (turns off) when the magnetic field dis...

The main gas detected is carbon monoxide, alcohol, acetone, paint thinner, formaldehyde and other slightly toxic gases. Features Low power consumption High sensitivity Tiny outline Responsive to a wide scope of target gases Cost efficient Durable Compatible with 5V and 3.3V

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 control the content on the display, this even includes the luminance of the display. For projects t...

It can detect the change in capacitance when a finger is nearby. This means no matter if your finger directly touches the pad or just stays close to the pad, the Grove - Touch Sensor will output HIGH. Grove - Touch Sensor enables you to replace press with touch.

It is mainly used in mechanical motion control, Like CNC milling machine, laser cutter, 3D printer, it also can used in robot platform motion control! Specification：   •Phase: 2 •Step Angle: 1.8° •Voltage: 12/24 •Resistance: 11ohm •Rate Current: 0.45A/Phase •Phase Resistance: 7.5ohm/Phase...

An infrared LED is like any other LED, with its color centered around 940nm. We can not only use the emitter to transmit data or commands, but also to emulate remotes to control your home appliance using an Arduino. The Infrared Emitter can transmit signals reliable up to 10 meters. Beyond 10 me...

There is an IR detector on the Infrared Receiver which is used to get the infrared light emitted by the Infrared Emitter. The IR detector have a demodulator inside that looks for modulated IR at 38 KHz. The Infrared Receiver can receive signals well within 10 meters. If more than 10 meters , the ...

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

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 place. It can be connected to a microcontroller with I2C (integrated with Grove socket) or throug...

What does “P” mean? “P” is for “panel mount” in this product. This Grove – Button is a sister version of original Grove - Button. They are identical except the Grove connecter is moved to the back so that you can easily use it as a neat and wire-free human interface device.

This 3-Axis Digital Accelerometer(±16g) is based on the low power consuming IC ADXL345. It features up to 10,000g high shock survivability and has a configurable samples per second rate. For applications that don’t require too large measurement range, this is a great choice because it’s durable, ...

The kit uses JGA25 DC geared motors and optical encoders for higher motor control accuracy and double-layer acrylic plates for easy placement of sensors and development boards. With this kit you can assemble your balance car, a mini Segway, or your personal project. Select the right sensor and de...

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 a typical Grove module now, without jumper wires clutter.But if you feel more like a proto servo, ch...

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.

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 by the photosensor(phototransistor). Any white (or lighter) colored surface reflects more than blac...

The piezo can be connected to digital outputs, and will emit a tone when the output is high. Alternatively it can be connected to an analog pulse-width modulation output to generate various tones and effects.  Grove - Buzzer is a simple yet enjoyable twig to use. It can output noise at a volume o...

We've already released the Grove - I2C Hub (4 Port), now comes the 6 port version, the same size, two more connectors, almost half the price! As you may know, the 7 address length I2C bus allows up to 128 I2C devices to access. At present, there are over 80 Grove I2C modules in Seeed, however, no...

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 emitting LED and sensitive phototransistor. When the phototransistor detects the reflected infrared...

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 sensor consists of an IR LED and a photo sensor (phototransistor). The light emitted by the IR LED gets reflected by any object placed in front of the sensor and this reflection is detected by the photo sensor (phototransistor). Any white (or lighter) colored surface reflects more than black ...

Inside the tilt switch is a pair of balls that make contact with the pins when the case is upright. Tilt the case over and the balls don’t touch, thus not making a connection. It is wired to the SIG line, NC is not used on this Grove module. Features Grove Interface Easy to use Simple Grove...

The Grove - Gas Sensor(MQ2) module is useful for gas leakage detection (in home and industry). It can detect combustible gas and smoke. The output voltage from the Gas sensor increases when the concentration of gas. Sensitivity can be adjusted by rotating the potentiometer. Please note that the b...

This is a multifunctional sensor that gives you temperature and relative humidity information at the same time. It utilizes a TH02 sensor that can meet measurement needs of general purposes. It provides reliable readings when environment humidity condition inbetween 0-80% RH, and temperature cond...

It is suitable for detecting Alcohol, Benzine, CH4, Hexane, LPG, CO. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer. Note:The sensor value only reflects the approximated t...
