Arduino Sensors

SKU: AF-4890 | Brand: Adafruit

Need to measure something with a very slim sensor? This precision 10K thermistor is an inexpensive way to measure temperature in a small gap, or taped to a flat surface, it's only 0.2mm wide!The resistance in 25°C is ...

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: 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...

This Reflective IR Sensor is a simple plastic casing with two elements - an IR LED and an IR phototransistor. You can control the IR LED and turn it on to bounce IR off objects to determine their reflectivity. Whit...

SKU: AF-157 | Brand: Adafruit

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller.To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to...
