The utility model relates to a pressure sensor module and pressure sensor based on passive RFID technique, include: metal plates, a plurality of telescoping shoring column and electronic tags, metal plates passes through telescoping shoring column with electronic tags is connected, the energy signal that electronic tags is used for receive radio frequency discernment RFID read write line to send was receiving after the energy signal, according to metal plates with electronic tags's position relation produces feedback signal, will feedback signal send for the RFID read write line. The utility model provides a based on the pressure sensor module of passive RFID technique, transmission through using the RFID technique can realize range signal far away has increased the transmission distance between pressure sensor module and the read write line.
