The "poor man's" accelerometer/motion sensor! These spring-vibration switches are medium sensitivity non-directional vibration induced trigger switches. Inside is a medium hardness spring coiled around a long metal...

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: AF-5578 | Brand: Adafruit

The BS612 is a compact, fully configurable mini PIR motion sensor that detects movement from approximately 3–8 metres away with a 120° detection spread. Its small form factor makes it ideal for unobtrusive motion-sens...

SKU: AF-3930 | Brand: Adafruit

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...

Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that s...

SKU: AF-3245 | Brand: Adafruit

Thermocouples are best used for measuring temperatures that can go above 100°C. This is a bare wires stainless-steel tip probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vi...

SKU: AF-4666 | Brand: Adafruit

A compact passive infrared (PIR) motion sensor that detects movement from approximately 3–8 metres away. Much smaller than standard PIR modules, making it ideal for unobtrusive, space-constrained projects. Fully self-...

SKU: AF-3986 | Brand: Adafruit

This T-Slot Photo Interrupter is a simple plastic sensor with two elements - an IR LED and an IR photo-transistor, situated across a U-shaped gap. You can control the IR LED and turn it on to transmit IR light acro...
