SKU: SF-COM-09117 | Brand: SparkFun

This is a 12-step rotary encoder with a nice ‘clicking’ feel. It’s breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an enc...

SKU: SF-SEN-18367 | Brand: SparkFun

A sealed, waterproof DS18B20 digital temperature probe for precise measurements in wet or harsh environments. The sensor communicates over a 1-Wire interface, requiring just one data pin (plus ground) to connect to yo...

SKU: DF-DFR0028 | Brand: DFRobot

This is an arduino tilt sensor. It is used to detect orientation. Inside the sensor, there is a ball that make contact with the pins when the case is upright. Tilt the sensor over and the balls don't touch, thus n...

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: 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-SEN0511 | Brand: DFRobot

This waterproof DS18B20 digital temperature sensor delivers accurate readings over a simple 1-Wire interface, requiring just a single data pin on your microcontroller. The sealed probe and silicone lead wire make it i...

SKU: EC-SPS40201S | Brand: Elecrow

This Elecrow 4-channel IR reflective sensor module combines four infrared emitter/receiver pairs with a mainboard that processes all signals. When an object enters the detection range, the corresponding channel output...

SKU: SF-COM-15141 | Brand: SparkFun

Rotary encoders can be used similarly to potentiometers. The difference being that an encoder has full rotation without limits (It just goes round and round). They output gray code so that you can tell how much and in...

SKU: SF-KIT-19518 | Brand: SparkFun

The SparkFun PIR Breakout Starter Kit includes everything needed to get started with passive infrared motion detection. Built around the Panasonic EKMB1107112 PIR sensor, this kit's breakout board offers ultra-low 1µA...

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-SEN0388 | Brand: DFRobot

This is a non-contact ultrasonic ranging sensor of high-performance from URM09 series, employing standard PH2.0-3P Gravity vertical interface. It provides an accuracy of 1% within an effective measuring range of 2~500...

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...
