Hello guys,
I have made a humidity controlled room by arduino. Somehow arduino freaked out during the night than stop to relay dehumidifiers. As result of that the room's humidity was about 100% when I check in the morning. After all, I reset arduino, everything was ok except dht11. It shows 20%, 80% 35% ... that happened 2 times. I realized that cause that I used wrong format of variables n they stuck arduino when reach format's limit. Anyway, the question is is that possible to save those dht11s?
I am sure you must have the data sheet and have the directions to restore the device.
"Placed under extreme operating conditions or chemical vapor sensors, through the following process, you can return it to the state calibration. <2 hours (drying) under 10% RH humidity conditions; then at 20-30 ℃ and> 45 ℃ and humidity under 70% RH conditions were maintained for more than 5 hours."
I don't see what a variable has to do with a non-functioning DHT11.
The DHT11 uses a basic resistive dew sensor element that can be exposed to 100%/condensation,
but the rest of the electronics inside the sensor might not like that.
Try drying it out with a hair drier, without making the sensor too hot.
We need all the details, code, wiring, etc if you need more help.
Read the forum posting guidelines first.
