This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.
Comes with solderable crimp pins and a mass attached to the tip. This mass increases the sensitivity to motion.
Is this not the cutest little display for the Raspberry Pi? It features a 2.8" display with 320x240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top!
Have you ever tried making a connection from your Raspberry Pi to a breadboard and had trouble finding the pin you need because nothing is labelled? Have you made mistakes matching a diagram of the pinout to the actual pins? Are you not making enough connections to use our amazing Pi Cobbler? Try the Raspberry Leaf!
Use this simple IR receiver for infrared remote control of your next project. With low power consumption and an easy to use package, it mates well with embedded electronics and can be used with common IR remotes.
The LM335Z is a very easy-to-use analog temperature sensor. The LM335Z works like a Zener diode with a breakdown voltage proportional to absolute temperature at 10mV/¡K. Hook up a resistor from 5V and GND, and the LM335Z will output an analog voltage of 2.98V (298 Kelvin is 25C or room temperature). The output of the sensor is linear, and when...
This sensor uses an infrared emitted diode combined with an infrared phototransistor to detect the reflected infrared signal. Ideal for sensing black-to-white transitions or can be used to detect nearby objects (.5-1cm).
These are the smallest NeoPixel breakouts around! Tiny, bright RGB pixels to your project. These little PCBs are only 8mm x 10mm and have two sets of three pads on the back for soldering wires. These ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable - so you only need 1 pin/wire to...
This is a very simple, clear infrared LED. These devices operate between 940-950nm and work well for generic IR systems including remote control and touch-less object sensing. Pair them with any of our IR receivers (see Related Items below). 1.5VDC forward voltage and 50mA max forward current
A vibration motor! This itty-bitty, shaftless vibratory motor is perfect for non-audible indicators. Use in any number of applications to indicate to the wearer when a status has changed. All moving parts are protected within the housing. With a 2-3.6V operating range, these units shake crazily at 3V. Once anchored to a PCB or within a pocket, the unit...
