I am trying to use a DHT11 sensor with 3 pins from my elegoo kit. I have followed the data sheet and connected the 3 pins correctly but each time I try and run different codes, I get this error: OSError: [Errno 110] ETIMEDOUT.
I am using DHT11 sensor in my arduino uno . the data format sent by the sensor is the following : 8bit integral RH data + 8bit decimal RH data + 8bit integral T data + 8bit decimal T data + 8bit ...
DHT11 does not send any floating point type. For each reading it sends 2 bytes: the integer value and the fractional value. So any NAN must be the result of your code. When developing code to read from devices, the first step is to print the raw data it is sending, and then you can see if that makes sense, according to the data sheet.
I am trying to read humidity and temperature values from the AM2301(DHT21). for that I am using the adafruit_dht library which is written for DHT11 & DHT22. because I can't find any adafruit li...
Have integrated Raspberry pi4 with a DHT sensor. The data pin is connected to pin GPIO 26 Have tried connecting the VCC to both 3.3V and 5V Have tried with both Adafruit_DHT.DHT11 and Adafruit_DHT....
2 From DHT11 datasheet, it only supports resolution to 1 degree Celsius and 8bits for humidity leading to the integer like floats. Also something to keep in mind is the units that the DHT11 and DHT22 output. Temperature is returned as Celsius and humidity is a value between 0 - 100 representing the relative humidity.
7 I am facing issues running DHT 11 temperature sensor in PI 2 with Python2.7 GPIO 0.5.11. I am referring to http://www.uugear.com/portfolio/dht11-humidity-temperature-sensor-module/ sample code. Same code works fine on PI 1 B+. In PI 2 i get "ERR_RANGE" as Error. I tried debugging the issue seems like data read @ GPIO pin 4 needs to be increased.
I programmed a freeRTOS on STM32F407 Can use 4x4 matrix keyboard to get data such as temperature and humidity below code is keyboard task that keep scanning 4x4 matrix keyboard's input. For example...
I've the same issue and, unfortunately, I've read that Java cannot read data from DHT11/22 in this way for timing problems. I've found in the Raspberry Forum a thread where you can find some solutions using SPI or pigpio.
