- DHT11 - difference between integral and decimal data
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 check sum the code I used is :
- DHT11 Error compiling for board Arduino Genuino Uno
#include "DHT11 h" ^ Indicates that the specified h file is not found Perhaps you need to install a DHT11 Arduino driver package With driver package properly installed, perhaps the line should instead be: #include <dht11 h>
- Raspberry PicoW + DHT11 error when reading sensor lt;bound_method gt;
I have a Pico running ‘pimoroni-picow-v1 19 1-micropython’ with a DHT11 connected When running main py I always get an <bound_method> output instead of the reading DHT11 is connected as follows: DOUT - GP28 GND - GND (32) VCC - 3V3 (30) Installed dht py from here Then I run this as main py:
- How can I get accurate value of temperature and humidity from DHT11 and . . .
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
- Getting NAN-Readings from DHT-11 Sensor - Stack Overflow
The first time I used the DHT11 everything went fine I tried the DHT11 for another application and I had that problem, the nan on my LCD1602 and on the serial monitor I thought it was the DHT11 which was defective, so I reloaded my old program to test the DHT11 The program worked fine with the new DHT11, so it wasn't the DHT11
- DHT11 sensor giving NAN for Temperature and Humidity
I have edited down an example from Adafruit for the DHT11 sensor, and have it working on an Arduino UNO You could try this simple code with your setup to help narrow down what is going wrong I have found that if I set the sensor to DH22 in the code rather than DHT11, it returns NAN - so it is possible that you have got the wrong sensor
- wrong humidity from a DHT11 sensor w Nano v3 - Stack Overflow
How do I get correct humidity readings from a DHT11 sensor, or do I just need better quality gear? The temp looks correct, humidity is not Remotely accurate humidity readings are needed for my project UPDATE: Tried the 3rd and all 3 are identical in behavior Same 40 point deficiency UPDATE #2:
- blynk - Esp8266 DHT11 Humidity Temperature but Failed to read from . . .
Help please I'm trying to get the sensor values from DHT11 Humidity amp; Temperature Sensor but the Esp8266 is connecting to internet but is not reading the value from the sensor I'm using Blynk
