My two DHT11 temp sensors measured my freezer at -19°C and -22°C. Should I be thrilled?

I did not purchase the sensors, but I am testing them. I used the Unified Sensor code.

I was pretty happy until I started researching online (to make sure the readings were accurate) and I keep reading that the DHT11 cannot measure negative numbers.

edit: These are Ardest DHT11 Temperature and Humidity Sensor Module, bought off of Amazon. I am unable to find temp range for these specific ones.

Am I witnessing a miracle? :stuck_out_tongue: Did I just luck out? Or should I be really worried?

For my project, I need to measure freezing temperatures.

Thank you!

It seems like you are correct.

But you didn't post your code, so who knows how the numbers actually emerged?

Why didn't you use a sealed temperature sensor, like the DS18B20, instead of a humidity sensor with exposed electronics.
