This is a force sensitive resistor with a round, 0.5" diameter, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg. Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. There is a...

This straight bar load cell (sometimes called a strain gauge) can translate up to 10kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the bar. With this gauge you will be able to tell just how heavy an object is, if an object's weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load...

After years of popularity with the XBee Series 1 and XBee Series 2, we now have the XBee Series 3 which brings the best of both worlds. XBee 3 not only handles 802.15.4, and ZigBee, but also BLE...

After years of popularity with the XBee Series 1 and XBee Series 2, we now have the XBee Series 3 which brings the best of both worlds. XBee 3 not only handles 802.15.4, and ZigBee, but also BLE protocols and you can now talk to the modules over UART or SPI as well. With a 200ft indoor range, or 4000ft outdoor/line-of-sight range, you can set up a mesh network to talk to or communicate with various devices around your house, work, or other area. This module has the familiar XBee package while...

The Raspberry Pi Zero Case has been designed to fit both the Pi Zero and the Pi Zero W. These official cases consist of several parts and protect the Raspberry Pi Zero from things like rogue wires that might short it out while still allowing full access to the board. Simply snap the RPi into the bottom half of the enclosure, then snap on a desired top. No tools required! Each case has a standard base featuring a cut-out to allow access to the GPIO, and a choice of three lids: a standard lid, a...

The SparkFun Qwiic Shield for Teensy provides you with a quick and easy way to enter into SparkFun's Qwiic ecosystem with your Teensy boards. This shield is sized to work with the footprint of Teensy 4.0, Teensy 3.2, and Teensy LC. This shield connects the I2C bus (GND, 3.3V, SDA, and SCL) on your Teensy to four SparkFun Qwiic connectors (two horizontally and two vertically mounted). The Qwiic ecosystem allows for easy daisy chaining so, as long as your devices are on different addresses, you...

The SparkFun Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once. The envelope output allows you to easily read amplitude of sound by simply measuring the analog voltage. Gain can be adjusted with...

Resistors are a good thing, in fact, they're actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear into thin air. The only way to be sure that you're gonna have the resistor you need when you need it is to stock up, and keep them organized. We have just the thing! Our new branded resistor kit comes with 25 each of 20 different resistor values (including 0Ω links!). All of these resistors are stapled into a tri-fold pack and clearly labeled. The...
