Description

This temperature & humidity sensor provides a pre-calibrated digital output. 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. 


Note: Please note that this sensor will not work when environmental temperatures is below 0℃.


Features

  • Relative Humidity and temperature measurement

  • Full range temperature compensation Calibrated

  • Digital signal Long term stability

  • Long transmission distance

  • Low power consumption

  • Low Cost

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.

Hi,you can't program it.This product is just a charger.

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.

The DHT11 does not provide any data for the "fractional" parts of the stream for both properties - temperature and humidity.

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.

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.

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.

Hello, I would like to ask, if it is possible to measure decimal value of temperature, or only entire value? Thank you for answer.

The way to use it is to pick off the plastic connector of solar panel.Very sorry about this .

There is no "decimal" value being returned by the sensor (for DHT11 devices). It will always be zero.

Hey Dineshkumar,you can refer to the wiki of this module, and you can see the maximum temp is 50 °C.

Also, keep the lower limit for the temperature, 0 degrees C, in perspective too (if applicable to your tests).

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

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.

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.

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

Hi there, correct. But down to 3.3v it can't do that.

Yes, you can.you can use jumper wire to connect them together.GND--GND,VCC--VCC,NC--No connection,SIG--A0.
