The Digilent PmodALS demonstrates light-to-digital sensing through a single ambient light sensor. Digilent Engineers designed this Pmod around Texas Instrument's ADC081S021 analog-to-digital converter and Vishay Semiconductor's TEMT6000X01.
A general purpose LED module in Grove form factor, available in different
colors. The ingenious PCB design enables you to bend the LED to any position you
want, which makes it easy to use it standalone, horizontal or Panel Mount(from

EMG detector is a bridge connects human body and electrical, the sensor
gathers small muscle signal then process with 2th amplify and filter, the output
signal can be recognized by Arduino. You can add this signal into your control
system. Note: The sensor cannot be used for medical purposes. In standby mode,
the output voltage is 1.5V. When detect muscle active, the output signal rise
up, the maximum voltage is 3.3V. You can use this sensor in 3.3V or 5V system.
The Hall Sensor measures the Hall Effect, which is a production of a voltage
difference across an electrical conductor, transverse to an electric current in
the conductor as well as a magnetic field perpendicular to the current. The
output of the continuous-time switch Hall sensor on this Twig switches low and
turns on when a magnetic field (south polarity) perpendicular to the Hall sensor
exceeds the BOP threshold, and it switches high and turn on when the magnetic
Grove - I2C ADC is a 12-bit precision ADC module based on ADC121C021. It
helps you increase the accuracy of value collected from analog sensor by
providing a constant reference voltage. Because its address is changeable, you
can use up to 9 I2C ADC at the same time at most. At the other hand, this module
provides auto sleep function which lowers the power consumption considerably.
This module is based on the color sensor TCS3414CS with digital output I2C.
Based on the 8*2 array of filtered photodiodes and 16-bits analog-to-digital
converters, you can gain the color chromaticity of ambient light or the color of
objects. Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have
blue filters and 4 have no filter(clear). With the synchronization input pin,
external pulsed light source can provides precise synchronous conversion
