RFD77402

Sensors Distance
1

Hi there!

i start to work with the sensor RF77402 and ESP8266. So i wrote a python library my problem is when i read the distance the error is so big like 40% for long distance and little more up for short distance. I use a white box for the test. I look the arduino library and the only thing i didn’t is calibration because be honest with you i don’t understand how work . Another thingh append if i try a read a distance more then 2000 mm i don’t receive any error like i saw in the data sheet . The sensor is V1.0. I hope someone can help me

Thank you so much

Hi Sergio, and thanks for your post.

Unfortunately we can’t assist you with your python code, but leaving out calibration is likely the cause of your accuracy issues. You might have a read through the [datasheet for the RFD77402 to see if that offers any clues that would help you implement calibration in python.

If anyone else has any suggestions, we would welcome you to post those as well.](https://cdn.sparkfun.com/assets/a/d/3/e/2/Simblee_RFD77402_Datasheet_Rev_1-8__1_.pdf)
