	One Wire Digital Temperature Sensor - DS18B20	This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-loggi...	$5.25	Ships in 24 hours
	Mini Photocell	This is a very small photocell. A photocell changes (also called a photodetector, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something). Features: Light resistance : ~1k Ohm...	$1.67	Ships in 7 Days
	Humidity and Temperature Sensor - DHT22	The DHT-22 is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn't require extra components so you can get right to measuring relative humidity and temperature. Features: 3.3-6V Input 1-1.5mA measuring current 40-50 uA standb...	$11.44	Ships in 24 hours
	Barometric Pressure Sensor - BMP085 Breakout	This is a simple breakout board for the BMP085 high-precision, low-power barometric pressure sensor. The BMP085 offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.03 hPa. It's based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability. This sensor suppo...	$21.00	Notify when back in stock.
	Hall Effect Sensor	The US1881 is an integrated Hall effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller, but can handle...	$1.00	Ships in 24 hours
	PIR Motion Sensor	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. Red wire is power (5 to 12V). Brown wire is GND. Black wire is open collector Alarm. This unit works great from 5 to 12V (datashe...	$11.44	Ships in 7 Days
	TMP36 - Temperature Sensor	TMP36 - Temperature Sensor sku: SEN-10988     This is the same temperature sensor that is included in our SparkFun Inventor's Kit. The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn't require an...	$1.65	Ships in 24 hours
	IR Receiver Diode	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 TSOP382 is a miniaturized receiver for infrared remote control systems. A PIN diode and a preamplifier are assembl...	$2.24	Ships in 7 Days
	Infrared Sensor Jumper Wire - 3-Pin JST	Three pin JST connector with red, black, and yellow colors. 5 inch wire outs. This cable comes fully assembled as shown and connects directly to many different Sharp sensors. Quick and easy, this cable will save you 15-20 minutes over making your own wiring harness.	$1.92	Ships in 7 Days
	Temperature Sensor - Waterproof (DS18B20)	Temperature Sensor - Waterproof (DS18B20) sku: SEN-11050   This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to b...	$12.00	Ships in 7 Days
	Digital Temperature Sensor Breakout - TMP102	This is a breakout board for the incredibly small TMP102 digital temperature sensor. The TMP102 is a digital sensor (I2C a.k.a. TWI), has a resolution of 0.0625°C, and is accurate up to 0.5°C. The sensor requires very low-current, and is loaded with features. Communication with the TMP102 is achieved through a two-wire se...	$6.53	Ships in 7 Days
	Temperature Sensor - LM335A	The LM335A is a very easy-to-use analog temperature sensor. The LM335A 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 LM335A will output an analog voltage of 2.98V (298 Kelvin is 25C or room temperature).  The output of the sensor is li...	$1.50	Notify when back in stock.
	Infrared Proximity Sensor - Sharp GP2Y0A21YK	Infrared proximity sensor made by Sharp. Part # GP2Y0A21YK has an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module. This is a really hard to find item!...	$15.72	Ships in 7 Days
	RFID Reader Breakout	This is a simple breakout board for our RFID readers. This board will bring the 2mm spaced pins out to two 0.1" spaced headers. You can solder the reader directly to the breakout board or use our 2mm sockets. Breakout board fits within and under the ID-12. The board also works with the ID-20, but is smaller than the edges o...	$1.22	Ships in 24 hours
	Force Sensitive Resistor 0.5"	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 sen...	$7.91	Ships in 7 Days
