Data Interface (Page 2)

Interfacing Cards, Computers, Sensors and Actuators.

Device networking for business, develops reliable products and technologies to connect and securely manage local or remote electronic devices over the network or via the web.

“Digi provides the essential layer of machine-to-machine (M2M) communications — the remote monitoring and management that critical applications depend on.”

Digi – Wireless Device Networking

External and embedded Wi-Fi products make it easy to add embedded 802.11a/b/g wireless LAN networking to any electronic device, or to connect serial devices over a Wi-Fi network.

The XBee Wi-Fi Cloud Kit includes all of the hardware and software tools needed to build a cloud-connected Wi-Fi prototype in under an hour. The Internet of Things has never been so simple!

delabs Notes

Digi is one of the Pioneers of Device Networking or M2M as it may be called now. Some call the Systems applying these technologies as “Internet of Things – IoT” today (Home and Office Automation).

Derived for this Device Networking term, we have “Wireless Sensor(and Actuator) Networks – WSN” in Industrial Automation. In Robotics it is  “Wireless Collaborative Robotics”.

If you see above closely, Sensor and Actuators with Intelligence is Robotics. So the dividing line disappears. The human is trying to make the machine more like him, both at work and play. Communications is important for that to happen.

Lantronix network enablement solutions connect almost any peripheral electronic device to a network or the Internet, enabling it to be remotely accessed, monitored and controlled. Have a look at the Networking Technology Tutorials.

How to Use Your PC to Measure Temperature

Thermocouple, RTD, Temperature monitoring is central to the majority of data acquisition systems, be it to save energy costs, increase safety, reduce testing time…whatever your reasons, you will need a device to measure the temperature – a temperature sensor.

How to Use Your PC to Measure Temperature

Thermocouples, resistance temperature devices (RTDs), thermistors and infrared thermometers are all types of temperature sensor. Which you choose depends on factors like your expected maximum and minimum temperatures, the accuracy you need and your environmental conditions.

752-RTD: RTD Resistance Temperature Measurement, Digital I/O, Counting, Analog Output

  • Measure temperature using RTDs or Pt100 sensors, and voltage signals
  • With extra hardware monitor thermocouples and strain gauge bridges
  • Includes the powerful yet easy-to-use Windmill software for Windows: no programming required
  • Connect up to 8 USB units to one PC

Here is a way you can learn, How To Interface PC to the Outside World.

Temperature Control with a PC

This is a project that will help students learn both hardware and software aspects of a control system. Here you can test out an automation program on a PC with minimum external hardware.

When you implement in the field, the system has to be a dedicated real time uC based product on custom firmware. Systems with OS + Software combination are not known to be reliable in Process Control. But OS + Software is good for Supervisory Systems which get their data from Real Time Controllers.

So a front end controller must be Rugged, Non-PC based and Non-OS based unit. This means use something like Arduino. With a Robust and Compact (means fast) firmware.

The firmware should be Polling or Interrupt based but with both internal and external watchdog. Most important a Power supply Management that resets system properly over Brown-outs and Black-outs. Even today some Embedded Systems i have to turn off and on after power resumes.

Don’t Forget, Multiple Watch Dogs and Multiple Power Management for graceful start of system !! Use one big SuperCap if you want. Else people will go back to Thermostats.
