Seeed Studio encourages DIY makers around the world to grow their inspirations into various projects, with motors, sensors, shields and more!
The Danger Shield is an add-on for the [Arduino] micro controller board. It contains a variety of fun and useful electronic circuits that you can use to do fun and useful things. It is a fully self-contained shield. You plug it into your Arduino, and you can immediately start using it. No extra things to hook up, no external components. Just a really rad board ready to rock.
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
left to right in below pics)
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
Grove - OLED Display 1.12" is an OLED monochrome 128×64dot matrix display
module with Grove 4pin I2C Interface .The characteristics of this display module
are high brightness, self-emission, high contrast ratio, slim outline, wide
viewing angle, wide temperature range, and low power consumption. It has bigger
screen and uses all the columns from the SSD1308 chip so that it can display
more contents than the OLED 96×16.
Grove - LED is designed for the beginners of Arduino/Seeeduino to monitor
controls from digital ports. It can be mounted to the surface of your box or
desk easily and used as pilot lamp for power or signal. Its brightness can be
adjusted by potentiometer.
This temperature & humidity sensor provides a pre-calibrated digital output.
A unique capacitive sensor element measures relative humidity and the
temperature is measured by a negative temperature coefficient (NTC) thermistor.
It has excellent reliability and long term stability. Please note that this
sensor will not work for temperatures below 0 degree.
This water sensor module is part of the Twig system. This sensor works by
having a series of exposed traces connected to ground and interlaced between the
grounded traces are the sens traces. The sensor traces have a weak pull-up
resistor of 1 MΩ. The resistor will pull the sensor trace value high until a
drop of water shorts the sensor trace to the grounded trace. Believe it or not
this circuit will work with the digital I/O pins of your Arduino or you can use
it with the analog pins to detect the amount of water induced contact between
the grounded and sensor traces.
With this wire, you can easily connect all of Seeed Grove modules to any 2.54mm pitch connectors. 5 PCs is included in one pack.Length of each wire is 20cm. Note: Grove side uses buckled connector.
Compared with the previous version, The Shield Bot V1.1 can use the usb port
of PC to charge battery. And the charging efficiency is greatly improved after
we optimize the circuit. And you can use the Arduino/Seeeduino Vin pin to fast
Note: Compatible Arduino Board not included, try the Seeeduino.
