Dimensions:

16.8mm diameter

9.3mm height without the pins

RoHS

Alcohol Gas Sensor MQ-3

This 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 analogue 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.

Features

  • 5V DC or AC circuit
  • Requires heater voltage
  • Operation Temp.: -10 to 70°C
  • Heater: less than 750mW

RoHS

Carbon Monoxide Sensor - MQ-7

This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO concentrations anywhere from 20 to 2000ppm.

This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

This sensor comes in a package similar to our MQ-3 alcohol sensor.

Fingerprint Scanner

RoHS

Fingerprint Scanner

The Nitgen RS232 serial fingerprint scanner is a powerful ADSP-BF531 Blackfin based system. 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.

Unit includes master controller board, optical reader, and ribbon cable to connect read to controller. We are trying to get pigtail interface cables made but in the interim, you will need to create your own connection to the serial connector.

Fingerprint Slide Scanner

RoHS

Fingerprint Slide Scanner

This 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.

RoHS

Optical Dust Sensor - GP2Y1010AU0F

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.

The sensor has a very low current consumption (20mA max, 11mA typical), and can be powered with up to 7VDC.

Polar Heart Rate Module

RoHS

Polar Heart Rate Module - RMCM01

This is a OEM module for the Polar Heart Rate system. This device works with any Polar heart rate strap to pickup the electromagnetic pulse and output a 1ms pulse indicating a heart beat has occurred. Embed a heart rate reading into your next project!

The RMCM01 requires no antenna. It does require a 32kHz crystal but that crystal does not need capacitors. Please see the basic schematic in the more information page.

Polar Heart Rate Monitor Interface

RoHS

Polar Heart Rate Monitor Interface

This 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.

It implements a sophisticated algorithm for computing an average heart rate even with noisy or intermittent data from the transmitter.
