SKU: AF-4097 | Brand: Adafruit

A versatile triple-axis digital accelerometer breakout featuring the Analog Devices ADXL343. With selectable sensitivity of ±2g, ±4g, ±8g, or ±16g and up to 13-bit resolution, this sensor handles everything from preci...

SKU: AF-4026 | Brand: Adafruit

The Adafruit STEMMA Soil Sensor uses capacitive measurement to detect soil moisture — a more durable approach than resistive sensors that corrode over time. With a single probe and no exposed metal, it avoids oxidatio...

SKU: SF-COM-09312 | Brand: SparkFun

The US1881 is a latching Hall effect sensor in a TO-92 package. When exposed to a magnetic field above the operating threshold, the open-collector output latches LOW and stays there until a reversed magnetic field pul...

SKU: AF-158 | Brand: Adafruit

Hall effect sensors detect whether a magnet is near. Useful for non-contact/waterproof type switches, position sensors, rotary/shaft encoders. I tried dozens of different hall effect sensors to see which one wou...

SKU: DF-SEN0171 | Brand: DFRobot

A passive infrared (PIR) motion sensor from DFRobot's Gravity series. It detects infrared radiation from people and animals in motion and outputs a digital HIGH signal when movement is detected — ideal for security sy...

SKU: DF-TEL0094 | Brand: DFRobot

You must have used a GPS receiver. It is easy to be found in most places, such as smartphones, cars, and computers. They are used to track your loaction all over the globe. GPS Receiver for Arduino is a unit embed...

SKU: DF-SEN0204 | Brand: DFRobot

A non-contact liquid level sensor that detects the presence of liquid through a container wall — no direct contact with the liquid required. Using advanced signal processing via the XKC-Y25-T12V chip, it works through...

SKU: DF-SEN0206 | Brand: DFRobot

INTRODUCTION We can divide temperature measurement in to two types: contact and non-contact. Contact measurement can only accurately measure temperature when the testing object and the se...
