A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor. It has excellent reliability and long term stability. Please note that this sensor will not work for temperatures below 0 degree. Features Relative Humidity and temperature measurement Full range temperature compensation Calibrated Digital signal Long term stability Long transmission distance Low power consumption Documents For all Grove users (especially beginners), we provide you guidance PDF documents.

Thanks. ae on Apr 14,2017 15:15 PM Reply upvote (0) 0 I am using the DHT11 sensor. However it only reads the integer temperature values with Python and Raspberry Pi. Please do let me know how to retrieve fractional value. ASHWIN PAJANKAR on Oct 19,2016 Reply upvote (0) Hi,you can't program it.This product is just a charger. Jacket Chen on Oct 20,2016 10:44 AM Reply upvote (0) The USB data is passed through, you can program your USB-connected device by plugging the Rider into your programmer's USB port. So the Teensy/whatever stays permanently connected to the Rider. Alex Satrapa on Oct 20,2016 10:50 AM Reply upvote (0) The DHT11 does not provide any data for the "fractional" parts of the stream for both properties - temperature and humidity. A Wajih on Nov 14,2016 22:32 PM Reply upvote (0) 0 I'm curious to know how it collects the data for two sensors on one analog pin? I can see that it works but just want to know how. Joshua Pritt on Oct 19,2016 Reply upvote (0) Hello,sorry for the late reply . Both the top layer and bottom layer copper fill connected to GND. We are sorry we didn't test like this before , thanks for you understanding. Deray Wu on Oct 20,2016 10:42 AM Reply upvote (0) The datasheet at http://www.micropik.com/PDF/dht11.pdf explains it all. The analog pin is used to return the return the data from the sensors (a little bit of nit-picking on my part, please do not mind). The measurements are done further upstream in the circuit. A Wajih on Nov 15,2016 01:30 AM Reply upvote (0) 0 Hello, I would like to ask, if it is possible to measure decimal value of temperature, or only entire value? Thank you for answer. on Oct 19,2016 Reply upvote (0) The way to use it is to pick off the plastic connector of solar panel.Very sorry about this . Deray Wu on Oct 20,2016 10:42 AM Reply upvote (0) There is no "decimal" value being returned by the sensor (for DHT11 devices). It will always be zero. A Wajih on Nov 14,2016 22:34 PM Reply upvote (0) 0 Can i know what is the max temp it can hold up. Or at wat temp this sensors melts Dineshkumar Balasubramanian on Oct 19,2016 Reply upvote (0) yes,it compatible. Deray Wu on Oct 20,2016 10:42 AM Reply upvote (0) Hey Dineshkumar,you can refer to the wiki of this module, and you can see the maximum temp is 50 C. Jacket Chen on Oct 20,2016 10:47 AM Reply upvote (0) Also, keep the lower limit for the temperature, 0 degrees C, in perspective too (if applicable to your tests). A Wajih on Nov 15,2016 01:31 AM Reply upvote (0) 0 Can you provide more details on the timing intervals used by the sensor to a) set up the communicationb) send each bit of dataThe only 'spec' I can find is the statement 'It costs 5mS for single time communication'.Do you have a more de Mike Brady on Oct 19,2016 Reply upvote (0) Yes??? you are totally right. Yuri Qiu on Oct 20,2016 10:41 AM Reply upvote (0) hi,the Sensitivity of Temperature is 1?C ,so we can't get the decimal part of temperature.And the Sensitivity of Humidity is ?1% .More detail ,watching wiki please.

A Wajih on Nov 15,2016 01:32 AM 0 Reply upvote (0) I've used sketch from adafruit, etc. also as in the wiki but didn't work, someone said those sketches don't match for my circuit, the sketches match for simple circuit like Uno, Mega, etc. VCC is 3.8V so the power is fine. I can read analog data from s Reply upvote (0) Iqbal on Oct 19,2016 Yes,it is. Reply upvote (0) Deray Wu on Oct 20,2016 10:42 AM 0 I need to interface this with 430 launchpad. Can you please let me know how to do this. I do not see any generic way of reading the output signal other than Arduino based library.

Reply Nir Azuelos on Oct 20,2016 10:41 AM upvote (0) I do not want to transplant the code, but need a generic way of communicate with the sensor irrespective of the controller I'm going to use. Datasheet would be very useful Reply Dhammika Kariyawasam on Oct 20,2016 10:44 AM upvote (0) 0 I'm wondering if I can use this with arduino Uno, if I can how can i connect this with arduino uno Reply upvote (0) Woo Seok Ko on Oct 19,2016 Hi there, correct. But down to 3.3v it can't do that. Reply upvote (0) Yuri Qiu on Oct 20,2016 10:41 AM Yes, you can.you can use jumper wire to connect them together.GND--GND,VCC--VCC,NC--No connection,SIG--A0. Reply Jacket Chen on Oct 20,2016 10:43 AM upvote (0) 0 Runs ok when powered by USB but doesn't work when board is powered by lithium battery.It then always fails on 'start condition 2'.Ideas? Reply upvote (0) Mike Brady on Oct 19,2016 Hi there, yes it is ok.If you use input with 5v.And about output it will change to 5V from battery. Reply upvote (0) Yuri Qiu on Oct 20,2016 10:41 AM Hi,Dear.This battery provides power supply for RTC, but can't act as the power source of stalker.
