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 ...

SKU: AF-161 | Brand: Adafruit

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ. To use, connect one side o...

SKU: EC-SPM32100S | Brand: Elecrow

This Moisture Sensor can be used to detect the moisture of soil or your pet plant's water level, let the plants in your garden reach out for human help. With the Octopus Electronic Bricks interface can very easy to us...

SKU: DF-DFR0076 | Brand: DFRobot

This Gravity analog flame sensor detects fire and infrared light sources in the 760–1,100 nm wavelength range. With a 60° detection angle and analogue output proportional to flame distance, it's widely used in firefig...

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 ...

SKU: AF-2765 | Brand: Adafruit

The Mini 2-Axis Analog Thumbstick is a compact, self-centring joystick with a black rocker cap, similar in style to PSP joysticks. It provides smooth directional analogue input using two 10 kΩ potentiometers — one for...

SKU: SF-SEN-14262 | Brand: SparkFun

The SparkFun Sound Detector is a small and very easy-to-use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound...

SKU: SF-SEN-09196 | Brand: SparkFun

This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple...

SKU: SF-BOB-12758 | Brand: SparkFun

The SparkFun Electret Microphone Breakout pairs a small electret microphone capsule with a 60× OPA344 op-amp preamplifier, making it easy to detect sound with a microcontroller's analogue-to-digital converter. Pick up...

SKU: AF-4543 | Brand: Adafruit

A 20 kg strain gauge load cell with four wires, featuring a metallic foil gauge bonded with epoxy to a solid aluminium bar. The aluminium constrains deflection and protects the gauge from damage. Mount one end to a fi...

SKU: DF-SEN0297 | Brand: DFRobot

The RP-C7.6-ST is a circular flexible thin-film pressure sensor with a compact 7.6 mm active area and ultra-thin 0.3 mm profile. It converts applied force into a variable resistance — output resistance decreases as pr...

SKU: DF-SEN0295 | Brand: DFRobot

The RP-C18.3-LT is a circular flexible thin-film pressure sensor, 18.3mm in diameter, designed for highly sensitive detection of both static and dynamic force. When pressure is applied to the active area, resistance d...

SKU: SF-SEN-13715 | Brand: SparkFun

This is a stainless steel, Type-K Thermocouple probe. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the othe...

SKU: AF-166 | Brand: Adafruit

The Interlink 402 is a round force-sensitive resistor (FSR) with a 12.7 mm (0.5″) sensing area. It changes resistance based on applied pressure — the harder you press, the lower the resistance — making it a simple, lo...

SKU: DF-SEN0170 | Brand: DFRobot

A three-cup anemometer kit with 0–5V analog voltage output for building custom weather stations and wind monitoring systems. The aluminium alloy construction provides high strength, weather resistance, and corrosion r...
