Zerynth Shield

Zerynth Shield: the shield that smartifies your objects

A ready to use multi-sensors board that adds smart functions to your everyday life objects.

The first shield that can be plugged on both Arduino and Particle boards without any adapter.

With a set of sensors on board and all the most used communication ports ready to be plugged, the Zerynth Shield allows makers, designers and IoT professionals to easily develop their smart objects, without care about wiring and soldering becoming crazy with funky circuits.

Empower Your Objects!

Social Safe Home

Create a home social network that notifies you and your family who is at home. If intrusions are detected you’ll receive a mobile notification while your neighbours a Facebook alert. In the meantime your house devices will turn into alarms: lights blinking, TV and Hi-Fi shouting at high volumes.

SmartPets

Humanize your pet through a smart device that monitors its feelings and tweets to you.

House Safety System

Never wonder again about GAS leakage, windows closing and other house devices state. Have you closed the valve before going bed? Have you closed the windows? No problem, check all of them with your smartphone!

Daily life metronome

Never start your day in a bad way! Get reminded to take your umbrella in a cloudy day, to get your bike during a metro strike or to take your grocery list when the fridge is empty.

Tech Specs

Sensors

Microphone

A small electret microphone amplified with a gain of 50X is used to allow detection of voice, door knocks, and similar sound and noises. The implemented circuit is based on a simple amplification stage followed by a buffer. The output of the microphone amplifier is connected to pin A3 on Arduino and A2 on Particle layouts.

Temperature

Zerynth Shield integrates a LM335 temperature sensor that can be used to read environmental temperature with a resolution of 0.5°C. LM35 has a linear output of 10mV/°C that can be read using an analog to digital converter. The LM35 output is connected to analog pin A4 on Arduino and A1 on Particle layouts. LM335 Datasheet

IR Receiver

The IR receiver is based on the TSOP38238 component that can be used to read signals from common IR remote controls at 38Khz, the same frequency used by several infrared devices like TVs, air conditioners and home theaters. The IR receiver require a digital input pin and it is connected to pin D2 on Arduino and to pin A4 on Particle layouts. TSOP38238 Datasheet

Light

Zerynth Shield integrates a photoresistors, also known as light dependent resistors (LDRs) or photocells. The used circuit is a simple voltage divider that allow a fairly accurate reading of the resistance in the photoresistor. The circuit out is connected to A5 on Arduino and to A0 on Particle layouts.

Touch

Zerynth Shield integrates a capacitive touch sensor based on AT42QT1010 chip. AT42Q is an integrated component used to convert any capacitive surface in a button. The AT42QT1010 sensor output is connected to pin D7 on Arduino and D7 on Particle layouts. The Touch pint ot be connected to the metallic surface to sensorize is available on the Expansion Connector (P1)
The surface to be sensorized have to be connected to the Touch pin available on the Expansion Connector (P1). There a GND pin is also available in order to allows the easy connection of a sensitive surface ground shield which is known to improve and stabilize the sensor sensitivity. AT42QT1010 Datasheet

Actuators

Piezo Buzzer

In the Zerynth Shield a little piezo buzzer is also integrated in order to allow the generation of beeps, tones and alerts. The piezo is powered through the not stabilized power line available on the SparkCore in order to avoid interferences with the sensors. The buzzer is driven through the PWM_BZ/MOSI pin that is connected to pin D8 on Arduino and pin A6 Particle layouts.
In order to enable SPI connection on the Zerynth shield the buzzer have to be disabled removing the dedicated jumper. The buzzer can be used to play tones from in the range 3,5 – 4,5 KHz.

IR LED Emitter

With the integrated IR Emitter the Zerynth Shield can become a remote controller for your home devices like TVs, monitors, Home Theaters, Air conditioners etc.
An IR LED driven by a BJT circuit is driven by the PWM_IRout pin connected to pin D6 on Arduino and to pin A on Particle layouts. The PWM is used to create infrared pulses at frequencies that can be received and decoded by common IR receivers.

Adafruit Neopixel LEDs

In the Zerynth Shield we also included a port dedicated to the connection of Adafruit Neopixel LEDs strips. LEDs power is connected to Sparkcore Vin and to the Arduino 5V. In order to avoid any damage to your Arduino or to your USB power supplier used for powering the Particle boards if your setup includes more than 24 LEDs you should use an external 5V power supplier for powering your LEDs using only the LED control pin and the GND of this Zerynth shield port.

Port pins are (GND; Vin; LED control pin; GND)

LEDs port digital control pin is connected to pin D9 on Arduino and to pin D2 on Particle layouts.

Expansion Connector

Zerynth shield also include an 8X2 pin header expansion connector that includes various pins and ports. Aux channels can be used for the connection of auxiliary sensors and actuator like Groove, Phidgets or Thinkerkit. Moreover, SPI and I2C ports are also available.

AUX Pins Properties

Zerynth shield also include a ready to use I2C port. The port has a pin order compatible with Groove I2C sensors and actuator (3.3; SCL; SDA; GND) allowing plug and play use of these modules. I2C devices of other producers can also be connected taking care of proper wiring.

SPI pins are also available on the expansion connector but not supported by the Particle Core

Zerynth Shield Library

Zerynth shield has been developed to simplify your life.

For this reason the Zerynth team is developing a dedicated control library for the Zerynth Shield. The Zerynth Shield control library is released together with the Zerynth Studio and will includes various high level ready to use functions like: sensor signals average, trend and filtering.

We are also developing a set of smart functions like “smart motion detection” which will allows to use the light sensor as people presence and movement detector or the “double click trigger” that will allow the use of the capacitive sensor as single and double “clicks” detector.
