Sensors & Modules

SKU: DF-SEN0448 | Brand: DFRobot

A 4-wire slot-type photoelectric switch with integrated optical transmitter and receiver. The 5mm detection slot can detect objects passing through, including transparent materials, making it ideal for counting, posit...

SKU: LB-PIR-CABLE | Brand: Little Bird

A compact passive infrared (PIR) motion sensor housed in a protective case with a 45cm cable. Detects motion within a 6-metre range and 120° field of view, making it ideal for security systems, automatic lighting, and...

SKU: DF-SEN0433 | Brand: DFRobot

A digital vibration sensor module that detects vibration using an internal inductance coil. When vibration is detected, the module outputs a LOW signal and its on-board LED indicator lights up. Sensitivity is adjustab...

SKU: SF-SEN-13285 | Brand: SparkFun

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.This unit works great from 5...

SKU: DF-SEN0595 | Brand: DFRobot

##Introduction This formaldehyde gas sensor differs from most gas sensors on the market as it does not provide specific gas concentration data. Instead, it detects whether the surrounding environment exceeds or falls ...

SKU: DF-SEN0596 | Brand: DFRobot

##Introduction This carbon monoxide gas sensor differs from most gas sensors on the market as it does not provide specific gas concentration data. Instead, it detects whether the surrounding environment exceeds or fal...

SKU: DF-FIT0759 | Brand: DFRobot

These Inductive Ring Proximity sensors are designed to detect metal objects entering or passing through the ring. They operate on a 6-36V power supply and offer NPN output. The sensor features less than 1ms response t...

SKU: DF-SEN0347 | Brand: DFRobot

This infrared photoelectric switch consists of a transmitter and receiver pair that detects objects at distances up to 1.5 m with a response time under 1 ms. The infrared beam provides stable detection regardless of a...

SKU: SF-COM-11102 | Brand: SparkFun

This 1024 pulse per rotation rotary encoder outputs gray code which you can interpret using a microcontroller and find out which direction the shaft is turning and by how much. This allows you to add feedback to motor...

SKU: PL-2482 | Brand: Pololu

The Pololu basic relay carrier modules allow simple control of a single-pole, double-throw (SPDT) switch from low-voltage, low-current control signals. This item includes the basic carrier PCB with a soldered-in 1...

SKU: DF-FIT0757 | Brand: DFRobot

These Inductive Ring Proximity sensors are designed to detect metal objects entering or passing through the ring. They operate on a 6-36V power supply and offer NPN output. The sensor features less than 1ms response t...

SKU: DF-FIT0758 | Brand: DFRobot

These Inductive Ring Proximity sensors are designed to detect metal objects entering or passing through the ring. They operate on a 6-36V power supply and offer NPN output. The sensor features less than 1ms response t...

SKU: EF-EF10030 | Brand: ElecFreaks

A passive infrared (PIR) motion sensor module based on the BISS0001 IC, capable of detecting human movement at up to 7 metres. Outputs a digital high signal when motion is detected, making it easy to interface with Ar...
