USA warehouse now open. Our USA warehouse is now open! Low cost shipping and an ever growing variety make ordering from the US warehouse even better value!
I got it working! It is a simple humidity sensor with a setpoint threshold. It measures Ambient Humidity in the 20 ~ 95% RH range. The digital output comes up when the analog value goes above the level set by the small potentiometer.
The 20 ~ 95% value is reversed (the value increases as the humidity decreases) and must be scaled. I'm goig to see if I'm able to post a sample code...
Ok, the test code is in the "Files" section ot this page. Now we have just to do the reversing and the scaling to add humidity reading to an Arduino project :)
For a long time looking Shield K-type Thermocouple ..
There is a cool option - oceancontrols****.au/KTA-259.html
But for me, it is not appropriate because of the huge size.
I need to remove 4.6 of temperatures from 300 to 960 degrees.
All repeat similar structures and no one has done such a multiplexer on the site.
The design is repeatable in size under the Nano.
Manufacturer can make a variety of boards and will release a version of a K-type Thermocouple ..
site does not make reference to stick (and sometimes it is necessary for the proper link will open in the correct cAm, the address and putting on the point) ...

Hi Guys,
do you know when this product will be really available? I am waiting since the 23/10/2012 and until now, there isn't in stock. Do you have any useful information about it?
Thanks a lot.
Hello,
I have the same problem. This is the Hobby King's answer:
Sorry for the inconvenience. Goods will be arrived within 45 days. Would you like to remove these back order or wait for a longer time? Please advise me.
Thanks for emailing support.
If you have any other questions, please let me know.
Regards.
A month waiting...
Was just wondering if anyone had got any useful info out of this sensor, or had found out what sensor this actually uses. I'm getting an analogue reading that changes with temp, but until I get some specs I don't know what voltage corresponds with what temp. And how to access humidity?
so u use an automated temp and humidity sensor for your grow room....er...i mean green house? i know u can put this in a robot. i thought that would be the primary use but, what is the primary function of the robot (all rc vehicles are in a sense robots)? volcano hunting? lol
It looks as it could be based on the DHT11 sensor. If that's the case, it uses single wire two way serial communication. So no problems transmitting several values.
Le problè*me c'est que la sortie digitale est une sortie de comparateur (LM393)! donc aucune chance d'avoir du multiplexage. C'est simplement le ré*sultat de la comparaison avec une valeur pré*dé*terminé*e par le potentiomè*tre. Le capteur n'a que 2 sorties, ce n'est pas un DHT11. HaCKaMac a la meilleure ré*ponse mais elle est fausse.
a good customer from the point of view of hobbyking staff? never give a truthful review, don't point out any flaws with new products, and always say "sir" before and after you say anything to any of the moderators.
I am waiting for arduino-sensors and LCDs as well, but this temp-sensor is useless for me. Gimme ultrasonic-sensors and motordriver shields and motors with encoder soon HK!
Pas de schéma comme d'habitude! Aucune référence à un site internet. Ce n'est pourtant pas si compliqué à faire!

Mesure l'humidité ou la température mais surement pas les deux à la foi puisqu'il y a une seule sortie analogique !
La sortie digitale est le résultat de la comparaison avec une valeur prédéterminée par le potentiomètre.

If I'm correct this is only humidity sensor, something like HR-202. If I'm wrong, could anyone post at least ID of this sensor? I've spent 2 days looking for arduino code for DHT 11, but it never worked. And appears that it is different product and description is wrong - this sensor can't measure temperature.
