Interface of Temperature Sensor(DHT11) with Arduino UNO tech for fun

DHT11 Temperature Sensor. Temperature Sensing is handled by the integrated NTC thermistor inside the DHT11 module. The NTC (Negative Temperature Coefficient) Thermistor is a resistor that has a negative proportion relationship with the temperature.The resistance of the NTC drops as the temperature increases and vice versa as indicated in the diagram below.

The problem is my Temperature, humidity have negative value and cant reading the temperature AC. when I try to use example DHTtester, DHT11 it can read the temperature on serial monitor but when I use in my project, the reading on OLED temperature-997C, Humidity-999%. How to fix this problem. Im new to arduino. Please Help. My code project


Wireless Temperature monitoring Using DHT11 Hackster.io

The DHT11 performs readings at a frequency of once per second (1Hz sampling rate), whereas the DHT22 takes readings once every two seconds (0.5Hz sampling rate). Despite these disparities, both sensors operate within a voltage range of 3 to 5 volts, with a maximum current of 2.5mA during conversion.

DHT11 Temperature And Humidity Sensor Module with LED

For the second component on DHT11, it is a Negative Temperature Coefficient (NTC) thermistor, when the temperature is rising, the resistance will decrease as follow. The chip will use that to determine the environment temperature. 1.3. Specification ¶ Supply Voltage: 3.3V to 5V Range of Temperature reading: 0-50°C with +- 2°C accuracy


DHT11 Temperature And Humidity Sensor Module with LED

So it should be something like temp = temp + percent * temp; where to add a percentage then percent is positive and to subtract a percent then percent is negative. percent is a float with the percentage divided by 100 as in 10 / 100 which is ..10. - Richard Chambers Sep 22, 2017 at 15:48 wherein the code would I add this? would this be the place?


Dht11 Basic Temperature Humidity Sensor Extras Test Measure Amp Inspect Riset

DHT11 Sensor. DHT11 can measure temperature from 0°C to 50°C with a ±2.0°C accuracy, and humidity from 20 to 80% with a 5% accuracy.. The term "NTC" stands for "Negative Temperature Coefficient," which means that resistance decreases as temperature rises.


Introduction to DHT11 The Engineering Projects

The DHT11 sensor can measure temperature and humidity in the air. It gives pre-calibrated digital output, so you can interface with any microcontroller like Arduino, ESP32, Raspberry Pi, etc.. The term "NTC" means "Negative Temperature Coefficient" which means its resistance decreases with increases in temperature.
