Ask for help interfacing with an SDI-12 sensor.
I am using Arduino Mega 2560 and used Arduino-SDI-12 library https://github.com/EnviroDIY/Arduino-SDI-12
and using Air Temperature and Relative Humidity Sensors / CS215-L from Campbell Scientific https://www.campbellsci.com/cs215-l.
The Sensor has been tested using Campbell Scientific datalogger it works correctly.
I've checked with an oscilloscope that the command is being sent correctly.
when i send command (data) to the sensor, the current drawn by the sensor reach more than 1 mA
The problem :( : There is no response from the sensor after sending any command to it ??!!
so, What should i do to overcome this problem??
Thanks in advance
