  Object, Distance and Motion Detection

Ultrasonic Sensor

The sensor measures distance using sonar; an ultrasonic pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return.

This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. Naturally, robotics applications are very popular but you'll also find this product to be useful in security systems or as an infrared replacement if so desired.
Range - 2cm to 3m (~.75" to 10'), Supply Voltage: 5V +/-10%
3-pin interface (power, ground, signal)
Burst Frequency - 40 kHz for 200 uS

PIR Motion Sensor

The PIR Sensor detects motion up to 20 feet away by using a Fresnel lens and infrared-sensitive element to detect changing patterns of passive infrared emitted by objects in its vicinity. Inexpensive and easy to use, it's ideal for alarm systems, motion-activated lighting, holiday props, and robotics applications.


  Color and Light

Color Sensor

A complete color detector, including a sensor chip, white LEDs, collimator lens, and standoffs to set the optimum sensing distance.
The sensor has an array of photodetectors, each with either a red, green, or blue filter, or no filter (clear). The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors. Internal to the device is an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color.

The sensor can detect and measure a nearly limitless range of visible colors. Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few.

Light to Frequency convertor

The sensor precisely measures light using an array of photodiodes, with an output of digital square waves. it has an input dynamic range of 160dB; that is, it can measure light over a range of 100,000,000-to-1

The programmable light-to-frequency converter combines a configurable silicon photodiode and a current-to-frequency converter on single monolithic CMOS integrated circuits. The output can be either a pulse train or a square wave with frequency directly proportional to light intensity. The sensitivity of the device is selectable and the output frequency can be scaled by one of four preset values. An output enable (OE) is provided that places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.


  Temperature and Humidity

Temperature and Humidity Sensor

It is a smart sensor for both humidity and temperature, and it comes in a tiny package that incorporates the analog to digital interface. All that the microcontroller has to do is read out the humidity and temperature values through the two-wire digital serial interface. The only math required is a simple scale and offset. It is factory calibrated so that it returns temperature with a resolution of 0.01 degrees Celsius and relative humidity with a resolution of 0.03 percent. The accuracy is better than most other sensors too.

Excellent for commercial or home-based projects that require such readings.
Temperature range: -40 F (-40 C) to +254.9 F (+123.8 C)
Humidity range: 0 to 100% RH

  Pressure or Force

Flexible Force & Load Sensor

The FlexiForce sensor measures force between two surfaces.
The sensor output exhibits a high degree of linearity, low hysteresis and minimal drift compared to other thin-film force sensors.
The single element sensor acts as a resistor in an electrical circuit. When the sensor is unloaded, its resistance is very high. Resistance decreases when force is applied to the sensor.
The sensor has an ideal output for A/D conversion - 0V is no force and 4.2V is 100 lbs.
The active sensing area is a .375" diameter circle at the end of the sensor. The conductive leads are easy to connect to a breadboard or through-hole area.
