TCS 3200 (Color Sensor)
NPR 680.00The TCS3200 programmable color light-to-frequency converter combines configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). The TCS3200 reads an 8×8 array of photodiodes.

4- Channel Arduino Relay Shield
NPR 650.00This relay module allows you to combine the processing power of the Arduino to devices that use higher current and voltage. It does so by providing four relays that are rated for 10A at 125VAC.
There are four relays that each provide dry contact outputs. That is to say that each relay provides a common (COM) , normally open (NO) and a normally closed (NC) terminal.

Analog accelerometer ADXL 335 (5V ready triple-axis with +-3g analog out))
NPR 600.00The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product
measures acceleration with a minimum full-scale range of ±3 g.
It can measure the static acceleration of gravity in tilt-sensing
applications, as well as dynamic acceleration resulting from
motion, shock, or vibration.The user selects the bandwidth of the accelerometer using the
CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.
Bandwidths can be selected to suit the application, with a
range of 0.5 Hz to 1600 Hz for the X and Y axes, and a range
of 0.5 Hz to 550 Hz for the Z axis.
The ADXL335 is available in a small, low profile, 4 mm ×
4 mm × 1.45 mm, 16-lead, plastic lead frame chip scale package
(LFCSP_LQ).FEATURES
3-axis sensing
Small, low profile package: 4 mm × 4 mm × 1.45 mm LFCSP
Low power : 350 μA (typical)
Single-supply operation: 1.8 V to 3.6 V
10,000 g shock survival
Excellent temperature stability
BW adjustment with a single capacitor per axis
