SKU: DF-SEN0523 | Brand: DFRobot

This IR break-beam photoelectric switch detects objects by sending an invisible infrared beam from an emitter to a receiver. When a non-transparent object passes between the two and breaks the beam, the receiver outpu...

SKU: PL-2485 | Brand: Pololu

The Pololu Basic 2-Channel SPDT Relay Carrier provides simple, independent control of two single-pole, double-throw (SPDT) relay switches from low-voltage, low-current control signals. This assembled version comes rea...

SKU: DF-SEN0216 | Brand: DFRobot

The Water Flow sensor measures the rate of a liquid flowing through it. The YF-S401 water flow sensor consists of a plastic valve body, flow rotor and hall effect sensor. It is usually used at the inlet end to det...

SKU: DF-DFR1084 | Brand: DFRobot

The Arduino UNO R4 WiFi is the latest evolution of the iconic UNO series, powered by the Renesas RA4M1 (Arm Cortex-M4) processor running at 48 MHz — a 3× speed increase over the UNO R3. With 256 KB flash, 32 KB SRAM, ...

SKU: AF-6109 | Brand: Adafruit

The Adafruit A4988 Stepper Motor Driver Breakout simplifies stepper motor control down to just two pins — a direction pin and a step pin. Each pulse on the step pin advances the motor by one step or microstep, making ...

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: DF-SEN0301 | Brand: DFRobot

This is an ultrasonic distance sensor(ULS) of high performance with an enclosed waterproof probe. The sensor, like many other ultrasonic sensors, based on the principle of ultrasonic echo ranging, determines the dista...

SKU: LB-LR0010 | Brand: Little Bird

Digital TempTemperature sensing module using an NTC thermistor. The output signal at ‘DO’ switches high when the preset (adjustable) temperature is reached. An analog output signal from the sensor is availab...

SKU: SF-SEN-09299 | Brand: SparkFun

The GP1A57HRJ00F is a slotted optical sensor (photo interrupter) with an infrared emitter on one upright and a shielded infrared detector on the other. When an object passes through the 10 mm gap between the uprights,...

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-SEN0151 | Brand: DFRobot

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...

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...

SKU: DF-SEN0300 | Brand: DFRobot

A high-performance waterproof ultrasonic distance sensor with an enclosed probe, capable of measuring distances from 270 mm to 8000 mm. Based on ultrasonic echo ranging, it determines distance by measuring the time be...
