Sensors & Input

SKU: SF-SEN-15901 | Brand: SparkFun

This Weather Meter Kit provides the three core sensors for a DIY weather station: an anemometer (wind speed), a wind vane (wind direction), and a rain gauge. All three sensors use passive magnetic reed switches rather...

SKU: DF-SEN0244 | Brand: DFRobot

The Gravity Analog TDS Sensor is an Arduino-compatible kit for measuring Total Dissolved Solids (TDS) in water. TDS indicates how many milligrams of soluble solids are dissolved per litre — the higher the value, the l...

SKU: SF-SEN-10293 | Brand: SparkFun

A simple piezo element that can be used as both a sensor and a small audio transducer. When flexed or tapped, it generates a voltage that can be read by a microcontroller, making it ideal for knock and vibration detec...

SKU: LB-LR0005 | Brand: Little Bird

The Line Trace Sensor Module uses an infrared emitter/detector pair to measure the reflectivity of a surface below it. When the reflectivity exceeds an adjustable threshold, the output goes low — making it ideal for b...

SKU: AF-1980 | Brand: Adafruit

The Adafruit TSL2591 is an ultra-high-range digital light sensor with a massive 600,000,000:1 dynamic range. It features both infrared and full-spectrum photodiodes, allowing you to separately measure infrared, full-s...

SKU: WS-24370 | Brand: Waveshare

The LC76G is a multi-GNSS positioning module that supports GPS, BeiDou (BDS), GLONASS, Galileo, and QZSS satellite systems. It allows multi-system combined or single-system independent positioning for fast, accurate l...

SKU: AF-5396 | Brand: Adafruit

The Adafruit VL53L4CD is a Time-of-Flight (ToF) distance sensor from ST that combines short-range and medium-range sensing in one chip. It measures from approximately 1 mm right up to 1300 mm, bridging the gap between...

SKU: DF-SEN0257 | Brand: DFRobot

The Gravity Analog Water Pressure Sensor measures water or gas pressure and outputs a linear 0.5–4.5 V analogue signal proportional to the applied pressure (0–1.6 MPa). Using the DFRobot Gravity 3-pin interface, it co...

SKU: DF-SEN0101 | Brand: DFRobot

An RGB colour sensor breakout board based on the TAOS TCS3200 chip, with four built-in white LEDs for illumination. The TCS3200 can detect and measure a wide range of visible colours by converting light intensity to a...

SKU: AF-3263 | Brand: Adafruit

The Adafruit Universal Thermocouple Amplifier MAX31856 Breakout reads temperature from virtually any thermocouple type — K, J, N, R, S, T, E, or B — with 0.0078125°C resolution and a measurement range of -210°C to +18...

SKU: LB-24-ATMOS | Brand: Little Bird

A compact barometric pressure and temperature sensor module that communicates over I2C. Ideal for weather stations, altitude estimation, and environmental monitoring projects with micro:bit, Arduino, or other microcon...

SKU: AF-4366 | Brand: Adafruit

The Adafruit TLV493D is a 3-axis magnetometer designed for detecting and tracking nearby magnets in three dimensions. Manufactured by Infineon, this sensor measures magnetic fields across the X, Y, and Z axes with 12-...

SKU: LB-LR0003 | Brand: Little Bird

This sound detection and microphone module provides both analogue and digital outputs for detecting sound with a microcontroller. The analogue output (AO) delivers a real-time voltage signal proportional to sound inte...

SKU: AF-1075 | Brand: Adafruit

A force-sensitive resistor (FSR) that changes its resistance based on how much pressure is applied. This Interlink 406 model features a 38 mm square sensing region, making it useful for detecting physical pressure, sq...

SKU: AF-4026 | Brand: Adafruit

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 oxidatio...

SKU: EF-EF04097 | Brand: ElecFreaks

The Octopus Capacitive Soil Moisture Sensor uses capacitive sensing to detect soil moisture levels, avoiding the corrosion problems common with resistive sensors for a much longer service life. It outputs an analogue ...

SKU: AF-5463 | Brand: Adafruit

This rubber sheet is made of the same carbon-black impregnated rubber material that our conductive rubber cord uses. Traditionally it would be used for EMF shielding, or conductive gaskets - but it's very fun to play ...
