bug: if user input obr_topic is sensor_gps_sate(wrong topic, which does not exist), the using of `strncmp` will assign idx=8 (as sesnor_gps) in the first.
However, there is no match in the `g_sensor_list`, hence idx=8 will give out value of `sensor_gps` as output(wrong).
Change: This update aims to match the whole value of sensor name in `g_sensor_list`, while keeping `sensor_name+number` match in this condition.
