Yesterday I was flying my Spark at around 360FT when I got this message - Downward infrared sensor failure ; Land immediately!
The weather was sort of of humid, as it rained earlier in the day. It probable was more humid at that altitude.

I landed the AC without any issuse (grabbed it in the air).

Afterwards I tried some landings and hoovering around and it seems everything is fine. The message no longer popping up.

Shall I be concerned at this moment?

Hi thanks for reaching DJI Forum, we do apologize if you had an issue with regards to your downward sensor. I'm pretty sure its only about the humid weather, moist affecting the sensor could be a big factor. You did mention that it did well during tested landings and hovering around.  I suggest just keep the aircraft updated, RC calibrated and updated as well and everything's going to be perfect. Have a safe flight always.

Hi Newuser_9, this was probably due to haze cause by a humid day, just like flying in fog.  Sensor may have gotten moisture on them giving you a warning and altitude might have also contributed to sensors not reading its bearing correctly.  Glad you got it back, safe and sound.

Whenever I flew my Spark, a warning always popped up saying "Downward infrared sensor failure - land immediately". This morning, I checked my Spark and noticed that one of the three sensors on the bottom of the aircraft had came out and was missing. Is this a normal thing? What should I do?
