IT’S OFFICIAL NOW:

I’ve been accepted to exhibit at @MakerFaire Bay Area on May 17 & 18, 2014 http://makerfaire.com/

#20475 – internet of farming arduino-based aquaponics

Will be able to show case a number of new leading edge things that I have been developing.

Here are just a few of them:

Design of a “Radial Flow Filter” for the tower unit system ( will be blogging and doing a Youtube video about it shortly”

Venturi DIY design that will replace air pumps on my systems.

Aquaponic Fog Unit that I have just completed and in testing mode now.

Have fully working Tower unit with totally enabled  IoT features that show case the latest developments in this technology as related to aquaponics.

New Product — DS18B20 — High Heat & Waterproof January 21, 2012

NEW PRODUCT – High Temp Waterproof DS18B20 Digital temperature sensor + extras. This is a pre-wired and waterproofed version of the DS18B20 sensor made with a PTFE wire cable. Handy for when you need to measure something far away, or in wet conditions. This sensor is a little more expensive than the other waterproof version we have with a PVC cable because this one can be used up to 125°C – the limit of the sensor itself.

Because the sensor signal is digital, you don’t get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.

The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex, and requires a bunch of code to parse out the communication. If you want something really simple, and you have an analog input pin, the TMP36 is trivial to get going.

We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor. We don’t have a detailed tutorial up yet but you can get started by using the Dallas Temperature Control Arduino library which requires also the OneWire Library.

Cable specs:

  • Stainless steel #306 tube 6mm diameter by 40mm long
  • Cable is 5 ft long / 150cm long
  • Contains DS18B20 temperature sensor
  • Three wires – Brown connects to 3-5V, Black connects to ground and Blue is data.

DS18B20 Technical specs:

  • Usable temperature range: -55 to 125°C (-67°F to +257°F)
  • 9 to 12 bit selectable resolution
  • Uses 1-Wire interface- requires only one digital pin for communication
  • Unique 64 bit ID burned into chip
  • Multiple sensors can share one pin
  • ±0.5°C Accuracy from -10°C to +85°C
  • Temperature-limit alarm system
