Alcohol Gas Sensor MQ-3This alcohol sensor is suitable for detecting alcohol concentration
on your breath, just like your common breathalyzer. It has a high
sensitivity and fast response time. Sensor provides an analog resistive
output based on alcohol concentration. The drive circuit is very simple,
all it needs is one resistor. A simple interface could be a 0-3.3V ADC.

Fingerprint ScannerThe Nitgen RS232 serial fingerprint scanner is a powerful ADSP-BF531
Blackfin based system. This scanner is capable of gathering and storing
unique finger prints.

Fingerprint ScannerThis is a low-cost finger print scanner with a slide type sensor
where the user slides their finger over the scanner. The ARA-ME-01 uses a
simple serial interface that makes identifying users by their finger
print fast and easy. This scanner is capable of gathering and storing
unique finger prints. Simply hold your finger on the optical scanner,
query the device over serial, and you will be issued a unique ID. Use
that ID within your embedded system to determine access levels, time
clocks, door locks, etc.

Fingerprint Scanner - 5V TTLFingerprint scanners are awesome. Why use a key when you have one
right at the tip of your finger? Unfortunately, they're usually
unreliable or difficult to implement. Well not anymore! We've found this
great fingerprint module from ADH-Tech that communicates over TTL
Serial so you can easily embed it into your next project.

LPG Gas Sensor - MQ-6This is a simple-to-use liquefied petroleum gas (LPG)
sensor, suitable for sensing LPG (composed of mostly propane and
butane) concentrations in the air. The MQ-6 can detect gas
concentrations anywhere from 200 to 10000ppm.
|
|
|
Methane CNG Gas Sensor - MQ-4This is a simple-to-use compressed natural gas (CNG)
sensor, suitable for sensing natural gas (composed of mostly Methane
[CH4]) concentrations in the air. The MQ-4 can detect natural gas
concentrations anywhere from 200 to 10000ppm.

Polar Heart Rate Monitor InterfaceThis is a wonderful evaluation board cooperatively designed by danjuliodesigns
and SparkFun. The Heart Rate Monitor Interface (HRMI) is an intelligent
peripheral device that converts the ECG signal from the Polar Heart Rate Monitor
(HRM) into easy-to-use heart rate data.

Polar Heart Rate ReceiverThe Polar Heart Rate Receiver is a Polar WearLink compatible receiver capable of wirelessly receiving coded heart beat transmissions from a Polar WearLink+ Heart Rate Sensor. With its standard servo interface pinout (Vss, Vdd, Sig), interfacing with this receiver is very simple - upon receipt of a heart beat signal, a 15 ms pulse is sent on the signal pin. This receiver also features a longer reception distance, giving you added flexibility in your application. 27,45 EUR incl. 19 % VAT excl. shipping costs

Sharp GP2Y1010AU0F (Optical Dust Sensor)Sharp's GP2Y1010AU0F is an optical air quality sensor, designed to
sense dust particles. An infrared emitting diode and a phototransistor
are diagonally arranged into this device, to allow it to detect the
reflected light of dust in air. It is especially effective in detecting
very fine particles like cigarette smoke, and is commonly used in air
purifier systems.
