GSM/GPRS Relay Control Module

SMS GSM/GPRS Bluetoth Relay and Sensors

Remote Control Module Relays and Sensors Trought SMS with GSM/GPRS

Control remotely via SMS or Bluetooth relay switches and sensors, this device in GSM version includes a GSM module that operate with a SIM card from almost  any networks and works as a cellphone but with some interesting features, is also available in the version with Bluetooth software for Android devices.

The unit has four relays to be controlled independently or with input conditions, incorporates a temperature sensor and humidity, microSD card reader, Bluetooth and internal GSM antenna, also there is a connector inside to an external antenna, 1GB memory card is included.
In the card is made a record of temporal evolution of the sensor readings and the recording of operation carried out, with user identification records for safety reasons, the equipment requires a memory card inserted to work properly.
Can be defined a primary user with the ability to enable / disable the device remotely.
Depending on moldel that you chose GSM / GPRS, Bluetooth and embedded power supply, all within a watertight box IP65 with transparent lid which can be used to monitored equipment operation by analysis of LED´s inside.

It can be applied in various situations may be used for example to automate gates doors and windows, making remote control of central heating, irrigation systems, pumping centers, enabling and disabling security systems, or even reset or rebooting server or other machines.

Features
•Dual band: 900/1800 MHz
•10A 220V relay outputs, to drive heavy loads
•Surge and reverse voltage protection on all
the inputs
•Two Analog inputs with mode selection,
voltage mode (0-10V) or current mode (4-
20mA)
•Turn ON/OFF the outputs by sending SMS
•Alarm message service over SMS
•Simple configuration through any web
browser
•Caixa Estaque com tampa transparente
•4 LED’s for input status, 4 LED’s for output
status
•7V – 24V power supply, ideal for use in
heavy duty vehicles like buses, trucks
•Watchdog controller ensures reliable and
continuous operation
•RS232 hardware interface for programing (opcional)
•Firmware upgrade possibility

Price and features of various versions available. Until then I leave some preview images of the prototype testing.

SOON!! Prices and characteristics of the various versions.

Control Module GSM / GPRS Relays and Sensors

Control remotely via SMS or Bluetooth relay switches and sensors, the device is GSM version includes a module which is putting a SIM card from a wireless mobile networks and works as a mobile phone but with some interesting features, is also available in the version with Bluetooth software for Android devices.

The unit has four relays to be controlled independently, incorporates a temperature sensor and humidity, microSD card reader, Bluetooth and GSM antenna connector inside with external antenna, 1GB memory card included.
The card is made a record of temporal evolution of the sensor readings and the recording of transactions carried out with user records responsible for safety reasons, the equipment requires memory card inserted to function.
Can be defined a primary user with the ability to enable / disable the device remotely.
Depending on the summer offers GSM / GPRS, Bluetooth and embedded power supply, all within a watertight box IP65 with transparent lid which can be monitored equipment operation thanks to LED indication and diagnosis functions in this most sensitive.

It can be applied in various situations may for example be used to automate gates doors and windows, making remote control of central heating, irrigation systems, pumping centers, enabling and disabling security systems, or even reset routers or servers reboting

Mini Robotic Claw

Claw Drawning

Drawing Claw

I have in my plans to build a robotic arm. As I never build any similar project and this destined to build a scale model for testing electromechanical and software to aid the development of future machines.

When I was researching information about Hipocicloidal gearboxes, suggested by a friend, I thought to use in the base of the arm, but I don’t have yet enough information that satisfies me in that area decided to start the robotic arm in question on the other end.

A Garra

Revelou-se mais fácil achar vários projectos opensource de garras mecanizadas que iam de encontro com o que pretendia construir.
