SKU: DF-SEN0311 | Brand: DFRobot

A commercial-grade waterproof ultrasonic distance sensor with UART serial output. The A02YYUW features a much smaller blind zone (3 cm) and wider sensing angle than many comparable sensors, plus penetration through sm...

SKU: LB-LR0240 | Brand: Little Bird

This compact sound module lets a microcontroller detect the presence of loud sounds using its onboard microphone.It is designed for sound detection rather than audio recording or interpretation. An Arduino can read th...

SKU: DF-DFR0129 | Brand: DFRobot

A capacitive touch sensor kit for Arduino based on the MPR121 touch controller. Includes three interchangeable touch pads — a scroll wheel, a keypad with backlight support, and a grid pad for gesture and pattern recog...

SKU: AF-189 | Brand: Adafruit

PIR sensors are used to detect motion from pets/humanoids from about 20 feet away (possibly works on zombies, not guaranteed). This one has an adjustable delay before firing (approx 2-4 seconds), adjustable sensiti...

SKU: LB-LR0051 | Brand: Little Bird

A 4-channel relay module with opto-isolated inputs for safe, reliable switching of high-power loads. Each relay is rated for up to 10A at 250VAC or 30VDC, making it suitable for controlling lights, motors, heaters, an...

SKU: LB-10K-5 | Brand: Little Bird

A pack of five NTC thermistor temperature probes, each with a 1-metre wire lead for remote temperature sensing. These 10 KΩ (at 25°C) NTC sensors are sealed in a cylindrical metal probe for durability and are suitable...

SKU: DF-SEN0527 | Brand: DFRobot

The Fermion AHT20 is a high-precision, low-cost temperature and humidity sensor breakout from DFRobot. Built around an improved MEMS semiconductor capacitive humidity sensor element, it communicates over a standard I2...

SKU: AF-4632 | Brand: Adafruit

The Adafruit PMSA003I Air Quality Breakout is a compact laser-scattering particulate matter sensor with an I2C interface — a significant advantage over the UART-based sensors that dominate this category. Simply connec...

SKU: LB-24-RAIN | Brand: Little Bird

Give your projects weather awareness in seconds. This compact module detects the very first drop of rain and reports the strength of the shower, making it ideal for smart gardens, automatic window controls, mini weat...

SKU: AF-2472 | Brand: Adafruit

The Adafruit BNO055 breakout delivers complete 9-DOF orientation sensing with onboard sensor fusion — no complex algorithms to write yourself. The Bosch BNO055 combines an accelerometer, gyroscope, and magnetometer on...

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: AF-161 | Brand: Adafruit

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ. To use, connect one side o...

SKU: DF-DFR0296 | Brand: DFRobot

The Bluno Nano combines an Arduino Nano-compatible ATmega328 microcontroller with an integrated TI CC2540 Bluetooth 4.0 (BLE) module in a compact 53 × 19 mm form factor. It enables wireless communication, wireless pro...

SKU: SF-SEN-12650 | Brand: SparkFun

The AD8232 SparkFun Single Lead Heart Rate Monitor is a cost-effective board used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG or Electrocardiogram and output as a...
