We've already released the Grove - I2C Hub (4 Port) and the Grove - I2C Hub (6 Port). Wait, still not enough? Well well, we know you are seeking more. Here you are, we present you the Grove - 8 Channel I2C Hub. More importantly, this is more than just a superposition..

Instead of using a coil, solid-state relays (SSR) use power semiconductor devices such as thyristors and transistors. They provide a much faster switching speed than the mechanical relays. The Grove - 8-Channel Solid State Relay is based on the high-quality G3MC202P module, which allows yo..

AHT20 is a new generation of temperature and humidity sensor embedded with a dual-row flat and no-lead SMD package, suitable for the reflow soldering. AHT20 is equipped with a newly designed ASIC chip: an improved MEMS semiconductor capacitive humidity sensor, and a standard on-chip temperature sens..

Grove - Analog Microphone is based on the Knowles SPU0414HR5H-SB module using high-performance SiSonic MEMS technology. SiSonic MEMS is cutting edge of acoustic technology and gaining wide acceptance in many types of consumer electronics products. MEMS microphones offer an extremely-low-noise, ..

The Grove - Blue LED Button is stable and reliable button. With the built-in LED, you can apply it to many interesting projects. For example, you can use the LED to show the status of the button. A high-quality N-Channel MOSFET is used to control the LED to ensure the high switching speed and a low ..

Features Built-in 2KByte storage: support up to 100 fingerprints Powerful self-learning function: the more you use, the more accurate the recognition Selectable security level Small size, low power consumption,10uA for standby modeDescriptionThe Grove - Capaciti..

The Grove - Capacitive Moisture Sensor (Corrosion Resistant) is a soil moisture sensor based on capacitance changes. Compared with resistive sensors, capacitive sensors do not require direct exposure of the metal electrodes, which can significantly reduce the erosion of the electrodes. Hence, we cal..

The Grove - Capacitive Touch Slider Sensor (CY8C4014LQI) is a multifunctional touch sensor. You can touch the two buttons or slide on the 5-segment slider, each touch pad has a corresponding LED to indicate the touch status. Also we provide a default high interrupt pin, once you touch the button or ..

The Grove - CO2 & Temperature & Humidity Sensor (SCD30) is a high precision carbon dioxide sensor, which is based on Sensirion SCD30. The measuring range of this sensor is 0 ppm-40'000 ppm, and the measurement accuracy can reach to ±(30 ppm + 3%) between 400ppm to 10'000ppm. ..
