JEENODE USB DRIVER

Maintaining the right pH level is important to how well the plant can absorb nutrients. I want Vout to range from 0 to. It would be nice to have the list of boards that have one or not. The text describing the library notes a 4. This can only be accessed from the PC side of the connection as far as I am aware.

The problem ysb these is that there is no option except 5 that will work across all boards. After hooking the bridge, enviR and usb up to the laptop I could see data coming in over through the serial port- voila! It would be nice to have the list of boards that have one or not.

But I need to decode this serial communication Nor am I sure of the reason for the discrepancies you can see most of the packets are HEZ 51 85 42 51 3 but a few contain different values. My Setup In the last postI set up the first of what I hope is many hydroponics systems — including the plants all the way to the LED arrays for lighting.

I made a program, and I can see the status of jefnode zones on PC. Some boards, when connected to a computer, publish their serial number. I don’t know if the data exchanged via serial connector uses one of this protocol specifications. The first reading I got before adding Dyna-Gro was 50 ppm.

I will continue to evaluate jfenode but will probably go ahead and use JeeNodes or at least the RFM12B with JeeNodes as the wireless network for the home network sensor piece.

FTDI chips have a unique serial number programmed onto them.

It seemed to me the power supply tester circuit we are designing in Contextual Electronics is pretty close to what is needed to provide a constant current to the royal blue and red LEDs. The first thing it points out is how much more efficient red LEDs are to the other colors.

You may also be able to see a unqiue ID or address on the host side. I could now drill down and determine the pulse spec: Can easily be accessed from both sides of the connection. The amount of constant current is controlled by adjusting the voltage into the non-inverting op amp.

By building on the work of others like Jean-Claude, I can learn at a level of abstraction that is best suited for my abilities ieenode needs. There has also been thought and implementation into a simple I2C interface so that sensors that use I2C can be easily strung together.

As noted by a response from Martynj to a question I asked on the JeeLabs forum about different RF frequencies for home sensor networks: Jeenofe like the idea of simplifying, so instead of using floating point math and conversion to Fahrenheit, I used the getTemp function.

But a very small staff. Date – newest first Date – oldest first.

It would be great to get these documents. The least intrusive method, and probably the jeenodd reliable, would be to simply read back the code and sum-check it. Given a known resistor — R1 in the image — and a known programmable voltage — V2 in the image — the current can be adjusted to a range of constant current values. Join 2, other followers. I am hoping it provides some knowledge to a fellow n00b and hopefully those more versed in this area will let me know what could be better.

Hi there, if you get the PRT3 module, you can have all the content sent to you over a serial bus, in either ascii or c-bus format.

The text describing the library notes a 4. From my understanding it’s possible to plug something like the Jeenode USB http: Thomas80, Have you managed something?

I put three 3 inch net pots in the other bucket.
