  • High-concerned chemical: None
  • is_customized: Yes
  • Theory: Other
  • Model Number: DHT11
  • Material: Mixture
  • Type: Humidity Sensor
  • Output: Digital Sensor
  • Brand Name: keyestudio
  • Origin: Mainland China
  • Use: Humidity Sensor


This DHT11 Temperature and Humidity Sensor features calibrated digital signal output with the temperature and humidity sensor complex. Its technology ensures high reliability and excellent long-term stability. A high-performance 8-bit microcontroller is connected. This sensor includes a resistive element and a sense of wet NTC temperature measuring devices. It has excellent quality, fast response and anti-interference ability.
Each DHT11 sensor features extremely accurate calibration data of humidity calibration chamber. The single-wire serial interface system is integrated to make it quick and easy. Qualities of small size, low power, and 20-meter signal transmission distance make it a wide applied application and even the most demanding one.
Specification
  • Supply Voltage: +5 V

  • Temperature range: 0-50 °C error of ± 2 °C

  • Humidity: 20-90% RH ± 5% RH error

Sample code:
#include
dht11 DHT;
#define DHT11_PIN 4
void setup(){
Serial.begin(9600);
Serial.println(“DHT TEST PROGRAM “);
Serial.print(“LIBRARY VERSION: “);
Serial.println(DHT11LIB_VERSION);
Serial.println();
Serial.println(“Type,tstatus,tHumidity (%),tTemperature (C)”);
}
void loop(){
int chk;
Serial.print(“DHT11, t”);
chk = DHT.read(DHT11_PIN); // READ DATA
switch (chk){
case DHTLIB_OK:
Serial.print(“OK,t”);
break;
case DHTLIB_ERROR_CHECKSUM:
Serial.print(“Checksum error,t”);
break;
case DHTLIB_ERROR_TIMEOUT:
Serial.print(“Time out error,t”);
break;
default:
Serial.print(“Unknown error,t”);
break;
}
// DISPLAT DATA
Serial.print(DHT.humidity,1);
Serial.print(“,t”);
Serial.println(DHT.temperature,1);
delay(1000);
}
