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: 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: EF-EF03085 | Brand: ElecFreaks

The HC-SR04 is a widely used ultrasonic distance sensor that provides non-contact measurement from 2 cm to 450 cm with up to 3 mm resolution. It uses a 40 kHz ultrasonic transducer pair — one transmitter and one recei...

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: 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-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-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: DF-SEN0328 | Brand: DFRobot

The TF03 is an industrial-grade LiDAR sensor with a detection range of up to 100 m. Using pulsed time-of-flight (ToF) measurement, it delivers high accuracy in a compact 44 × 43 × 32 mm package weighing just 77 g. Its...
