SKU: SF-SEN-13322

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is...

SKU: DF-SEN0114

A resistive soil moisture sensor that reads the water content of surrounding soil by measuring electrical resistance between its two probes. Wetter soil conducts more easily (lower resistance), while dry soil conducts poorly (higher resistance) — giving you an analogue voltage output proportional...

SKU: SS-101020003

A simple momentary push button module in the Grove form factor. When pressed it outputs a HIGH signal; when released it returns to LOW. The button includes a built-in pull-down resistor, so it's ready to use as a digital input straight out of the box. Part of the Seeed Studio Grove ecosystem, it...

SKU: AF-4026

The Adafruit STEMMA Soil Sensor uses capacitive measurement to detect soil moisture — a more durable approach than resistive sensors that corrode over time. With a single probe and no exposed metal, it avoids oxidation issues and won't introduce DC currents into your plants. The ATSAMD10 microco...

SKU: DF-SEN0394

The Gravity SGP40 Air Quality Sensor uses Sensirion's SGP40 digital VOC sensor chip with built-in temperature and humidity compensation. It outputs a VOC index (0–500) that can be used directly to evaluate indoor air quality without calibration. The Gravity interface provides plug-and-play connec...

SKU: DF-SEN0152

Ultrasonic sensors emit ultrasonic pulses, and by measuring the time of ultrasonic pulse reaches the object and back to the transducer, the distance of sensor from the target object is calculated. They are widely used in detecting displacement, thickness, distance, water level, material level and...

SKU: EF-EF04090

The Octopus PM2.5 module from ElecFreaks is a laser-based particulate matter sensor built around the ZH03B dust sensor. It measures PM2.5 concentration in the air with high consistency and real-time response, capable of detecting particles as small as 0.3 µm in diameter. Part of the Octopus elec...

SKU: SS-101020023

The Sound sensor module is a simple microphone. Based on the power amplifier LM386 and the electret microphone, it can be used to detect the sound strength of the environment. The value of output can be adjusted by the potentiometer.   Features Grove compatible interface Wide supply vo...

SKU: AF-4528

A 100 mm adapter cable that bridges the gap between Grove and STEMMA QT / Qwiic ecosystems. One end features a Grove connector, the other a JST SH (STEMMA QT / Qwiic compatible) connector — making it easy to mix and match sensors, breakouts, and host boards across different connector standards. ...

SKU: SS-110010044

The Grove Starter Kit for Seeed Studio XIAO bundles the XIAO Expansion Board with 9 Grove modules and additional components, providing a complete introduction to the XIAO development platform. Designed for beginners, it comes with free online courses to help you get started quickly. The kit cove...

SKU: AF-4424

A 200mm adapter cable with a JST-SH 4-pin connector (STEMMA QT / Qwiic, 1mm pitch) on one end and a JST-PH 4-pin connector (STEMMA / Grove, 2mm pitch) on the other. Use it to bridge I2C sensors and drivers between the two connector ecosystems. Both connectors have a latching feel for secure conn...

SKU: EF-EF04060

The Octopus MQ3 Alcohol Sensor Brick from ElecFreaks is an analogue gas sensor module with high sensitivity to alcohol vapour. It outputs an analogue voltage proportional to the detected alcohol concentration, making it straightforward to interface with Arduino and other microcontrollers. The MQ...
