SKU: LB-LR0018 | Brand: Little Bird

A compact reed switch module that closes its circuit when a magnetic field is present. Inside the glass envelope, a pair of ferromagnetic metal contacts come together when a magnet is brought close, and spring apart w...

SKU: SF-SEN-09299 | Brand: SparkFun

The GP1A57HRJ00F is a slotted optical sensor (photo interrupter) with an infrared emitter on one upright and a shielded infrared detector on the other. When an object passes through the 10 mm gap between the uprights,...

SKU: SF-SEN-13835 | Brand: SparkFun

The SST Liquid Level Sensor provides single-point liquid detection via a TTL-compatible push/pull output. Its miniature optical design allows installation in tight spaces where traditional float switches won't fit. A...

SKU: SF-SEN-13285 | Brand: SparkFun

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.This unit works great from 5...
