DHT11 digital temperature and humidity sensor is a calibrated digital signal output temperature and humidity combined sensor, which application-specific modules capture technology and digital temperature and humidity sensor technology to ensure that products with high reliability and excellent long-term stability.

Description

Technical parameters:
Supply voltage: 3.3 to 5.5VDC
Output: single-bus digital signal
Measuring range: Humidity 20% to 90% RH, Temperature 0 to 50 celsius degree
Accuracy: Humidity +&-5% RH, temperature +&-2 celsius degree
Resolution: Humidity 1% RH, temperature 1 celsius degree
Long-term stability: less +&-1% RH per Year

Notes:
1. To avoid the use of the condensation conditions
2. Long-term storage temperature 10 to 40 celsius degree, humidity below 60%
3. The use of power and ground connection to be correct, so as not to damage the sensor
