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...

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.  

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 met...

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 ...

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, ...

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 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 ...

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...

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 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 con...

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 ...

It is built with MQ303A semiconductor alcohol sensor. It has good sensitivity and fast response to alcohol, making it suitable for building a breathalyzer. This Grove module implements all the necessary circuitry for the MQ303A, such as power conditioning and heater power supply. This sensor outp...
