this sec on to accelerate its recovery. Please be aware that opera ng the DHT11 sensor in the

non-normal working condi ons will accelerate sensor’s aging process.

(2) Attention to chemical materials

Vapor from chemical materials may interfere with DHT’s sensi ve-elements and debase its

sensi vity. A high degree of chemical contamina on can permanently damage the sensor.

(3) Restoration process when (1) & (2) happen

Step one: Keep the DHT sensor at the condi on of Temperature 50~60Celsius, humidity <10%RH

for 2 hours;

Step two:K keep the DHT sensor at the condi on of Temperature 20~30Celsius, humidity

>70%RH for 5 hours.

(4) Temperature

ect

Rela ve humidity largely depends on temperature. Although temperature compensa on

technology is used to ensure accurate measurement of RH, it is s strongly advised to keep the

humidity and temperature sensors working under the same temperature. DHT11 should be

mounted at the place as far as possible from parts that may generate heat.

(5) Ligh t

ect

Long me exposure to strong sunlight and ultraviolet may debase DHT’s performance.

(6) Connection wires

The quality of connec on wires will affect the quality and distance of communica on and high

quality shielding-wire is recommended.

(7) Other attentions

* Welding temperature should be bellow 260Celsius and contact should take less than 10

seconds.

* Avoid using the sensor under dew condi on.

* Do not use this product in safety or emergency stop devices or any other occasion that failure

of DHT11 may cause personal injury.

* Storage: Keep the sensor at temperature 10-40

℃, humidity <60%RH.
