Yocto-meteo

Yocto-Meteo

  

Your own USB weather station: the Yocto-Meteo device will let you measure via USB the current humidity, pressure, and temperature, as well as record the pressure, ambient temperature and humidity on its internal flash for later retrieval when connected again by USB (built-in data logger). This product is the ideal to build your own DIY weather station, and to monitor the weather conditions in your garden.

This meter circuit has been designed so that the sensor itself can be moved further away from the USB connector by a few meters: simply split the board into two parts and solder a 4-wire cable on the designated pads.

Note: earlier versions of this product were less accurate; for details, refer to the manual.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.

C'est pas dommage qu'il n'y ait pas une entrée pour une éolienne vitesse/direction?

2 - martinm (Yocto-Team)Tuesday,february 07,2012 7H38

C'est trop dépendant du modèle d'éolienne utilisé. Par contre il n'est pas exclu que l'on fasse un jour un module compte-tours, à charge de l'utilisateur de l'adapter à son éolienne.

Hello,
I'm on the market for a server room monitoring system and I came across your website.
I think your products are great, but since I have no experience in programming, I would like to know if there's any commercial application for os x or iOS based on your hardware.
Thank you.

4 - martinm (Yocto-Team)Monday,august 13,2012 6H54

@odp_12:

We are not aware of any publicly available OS X/iOS commercial application using our modules. However our libraries are provided with a few useful pre-compiled examples. If you have specific needs, just send a mail to Yoctopuce support, our software department might be able to help.

Hello,

i just find your fantastic products and have questions.
Can i connect this weather station with yoctohub-ethernet (and how much max. length of UTP cable can be)?
And is there template of weather station for cacti monitoring system? if not, can your application export automatic in txt file results (to grab for cacti)?

Thank you for answers!

6 - martinm (Yocto-Team)Sunday,september 09,2012 7H09

@Yoda

Hi, Yes the Yocto-Meteo will be compatible with the Yoctohub-Ethernet, the maximum cable length should be standard (around 100m for a CAT 5 cable).

Regarding Cacti monitoring system, tunneling data from the Yocto-Meteo to Cacti should be a formality: Cacti provides PHP based data gathering scripts, and our devices can be driven with PHP. This even looks looks like a good subject for a post in our blog, stay tuned :-)

thank you for answer martinm.
and last question, can yoctohub-ethernet get power for himself and yocto-meteo over POE (if yes, what is the voltage)?

Thank you!

8 - martinm (Yocto-Team)Monday,september 10,2012 9H20

@yoda

Yes, the Yoctohub-Ethernet will support POE and will be able to power the Yocto-devices connected to it, Yocto-Meteo included. All our devices require 5 volts to work when powered directly from USB socket. The POE input will follow IEEE802.3af and accept from 37V to 55V (either in mode A or mode B).

@odp_12

We don't know of an Apple application for server room monitoring, however Valarm provides an Android ( often cheaper devices than Apple! ) solution for server room monitoring. With Valarm you can connect an economical device to the Yocto-Temperature and get SMS and/or email alerts when the temperature goes out of a specified range. Valarm ( the Versatile Asset Locator And Remote Monitor ) has also implemented other functionalities ( such as asset & fleet tracking ) and is adding more and more support for various sensors. See http://www.valarm.net for full details.

The Valarm app is available directly at https://play.google.com/store/apps/details?id=net.valarm.android.pro

If you have any other comments or questions don't hesitate to ask!

Cheers,
Edward.

hello,

can i connect a Bluetooth module to the Meteo device to transfer realtime data to a phone, tablet or desktop computer ?

if yes, any specific bt module ?

regards
T. Chrigui

Hello,

how much current does this module draw when logging, and how tight is the 5V specification?
Would it be feasible to power this for logging purposes from a 4x1.5V household battery pack?

Thanks, lino

@chrigui

I haver never heard of an USB-over-bluetooth adapter. USB-over-WiFi exists and works however.

@lino

The CPU and sensors for the Yocto-Meteo are all behind 3.3V regulator, so as long as input voltage is above 3.6V you should have no problem. The module uses approx 25mA, so if you use 2500mAh batteries, you can hope to run for around 4 days. But we have never tried it :-)

13 - lino Friday,february 01,2013 1H07

@mvuilleu Ah, that's too much current draw for long-term logging on batteries... I could use a USB power supply, but need to preserve the timestamps through short power cuts, and while the USB cable is changed over. Hmmm, perhaps a supercap could be added?

14 - mvuilleu (Yocto-Team)Friday,february 01,2013 12H10

@lino There is still hope: we work on a new USB timer device that will let you automatically power on and off a device (or low-power computer) based on a schedule. That timer will be able to run from batteries, consuming almost no current at all while sleeping.

15 - lino Sunday,february 10,2013 11H38

I don't think that would fit my use case.... I do have mains power at the typical logging locations, the issue is that I need the time stamps to be correct. A supercap could bridge short power interruptions, and also the time it takes to change over the USB cable from laptop/smartphone (reading out data on a maintenance visit) to a power supply. (For the latter I could also use a powered USB hub or a Y-cable, but I want to make things as idiot-proof as possible out in the field.)

16 - martinm (Yocto-Team)Sunday,february 10,2013 12H36

@lino: if you need at least 300 Yocto-meteo able a keep time when unplugged, just contact support, we could probably build customized versions.

17 - tobiasv Friday,july 12,2013 13H08

Is there a way this could be powered by a solar power cell?
I'd love to see wireless communication as well..

In other words I want a virtually permanent continuous logging weather station. :)

18 - martinm (Yocto-Team)Friday,july 12,2013 13H19

@tobiasv: actually we are working on a Wifi version of the Yocto-Meteo. We are also working on a Wifi Hub for our devices (see: www.yoctopuce.com/EN/products/vaporware/yoctohub-wireless). These will have an electic consumption small enough to be battery / solar powered.

Yoctopuce, get your stuff connected.
