Python SDK for SenseID smart sensor tags — parse RAIN RFID, BLE and NFC sensor data, and control supported readers

senseid

Python SDK for SenseID smart sensor tags. Parse sensor data from RAIN RFID, BLE, and NFC tags, and control supported reader devices through a unified interface.

Features

• Multi-technology parsing: Decode SenseID sensor data from RAIN (UHF RFID), BLE beacons, and NFC tags
• Unified reader interface: Control different RFID/NFC readers through a single API
• Auto-discovery: Scan for supported readers via serial port, mDNS, and PC/SC
• YAML-driven definitions: Tag types and sensor calibration defined in YAML files
• Sensor data extraction: Temperature, humidity, and other magnitudes with automatic calibration

Installation

pip install senseid

Quick Start

Parse a RAIN RFID tag

from senseid.parsers.rain import SenseidRainTag

tag = SenseidRainTag('000000F1D301010000012301')
print(tag.name)          # Tag model name
print(tag.sn)            # Serial number
for d in tag.data:
    print(f"{d.magnitude}: {d.value} {d.unit_short}")

Scan for readers and run inventory

from senseid.parsers import SenseidTag
from senseid.readers import SupportedSenseidReader, create_SenseidReader
from senseid.readers.scanner import SenseidReaderScanner

scanner = SenseidReaderScanner(autostart=True)
connection_info = scanner.wait_for_reader_of_type(SupportedSenseidReader.IMPINJ_IOT, timeout_s=10)
scanner.stop()

if connection_info is None:
    print('No reader found')
    exit()

reader = create_SenseidReader(connection_info)
reader.connect(connection_info.connection_string)

def on_tag(tag: SenseidTag):
    print(f"{tag.name} | SN: {tag.sn} | {tag.data}")

reader.start_inventory_async(notification_callback=on_tag)
input("Press Enter to stop...")
reader.stop_inventory_async()
reader.disconnect()

API Reference

Parsers

SenseidRainTag(epc: str | bytearray)

Parses a RAIN RFID EPC into a SenseidTag with decoded sensor data. Accepts hex string or bytearray.

SenseidBleTag(beacon: str | bytearray)

Parses a BLE advertisement payload into a SenseidTag.

parse_nfc_ndef(ndef_data: bytearray, uid: str) -> (SenseidTag, type_id)

Parses NFC NDEF data into a SenseidTag.
