概覽

AI 產生的概覽

透過 USB 讀取 Senseca PRO 111/115 溫度計的即時溫度與 Pt100 電阻，並支援取樣與裝置資訊查詢。

可以做什麼
  • 讀取目前溫度（含單位與 UTC 時間戳），或讀取 Pt100 探棒的電阻值（歐姆）
  • 在一段時間內記錄讀值（最長 600 秒，間隔至少 0.5 秒），回傳最小值、最大值、平均值、標準差及全部樣本
  • 查看儀器資訊：型號、序號、韌體、時鐘與電池電量
  • 開啟寫入模式後，可設定儀器時鐘或重新命名 20 個位置標籤之一
適用情境
適合需要讓助理處理 Senseca PRO 手持溫度計真實量測資料的情境，例如記錄一段溫度序列、查看探棒電阻，或在實驗室與現場作業中讀取裝置狀態。
執行需求
以 uvx 執行的本機程序，需要 Python 3.10 以上與 uv。儀器需開機並以 USB-C 連接（PRO 115 需將 USB 模式設為 COM 介面）。可用 SENSECA_PORT 指定序列埠，否則自動偵測；Linux 下使用者需屬於 dialout 群組。僅在儀器啟用保護模式時需要 SENSECA_PIN。
安裝前請注意
寫入類工具（時鐘、位置標籤）預設關閉，只有將 SENSECA_ALLOW_WRITE 設為 1 才會啟用，啟用後助理可變更儀器設定。SENSECA_PIN 為保護模式所需的密鑰。序列埠同一時間只能被一個程式佔用，執行時應關閉 ProXware 或終端機程式。USB 埠非電氣隔離，接觸接地介質時可能影響讀值。非官方專案，與 Senseca 無關聯。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Senseca PRO thermometer，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。

README

mcp-server-senseca-pro

An MCP server that lets AI assistants read live measurements from a Senseca PRO 111 / PRO 115 handheld Pt100 thermometer connected via USB.

Unofficial project, not affiliated with or endorsed by Senseca. Tested with a PRO 111, firmware V1.4.3.0, interface protocol V1.0.0.1.

Tools

ToolDescription
read_temperatureCurrent temperature with unit (°C/°F/K, as set on the instrument) and UTC timestamp
read_resistanceCurrent Pt100 resistance in ohm
sample_temperatureReadings over a period (max 600 s, interval ≥ 0.5 s) with min/max/mean/stdev
get_device_infoModel, serial number, firmware, instrument clock, battery level

With --allow-write two more tools are available:

ToolDescription
set_device_clockSet the instrument clock (default: this computer's time)
set_location_nameRename one of the 20 location labels

The server cannot change calibration or adjustment data; the instrument does not offer that over its serial interface.

Requirements

  • Python ≥ 3.10 and uv
  • The instrument switched on and connected via USB-C. On the PRO 115 set Settings → USB mode to COM interface.
  • Linux: your user must be in the dialout group (sudo usermod -aG dialout $USER, then log in again).
  • Windows / macOS: no extra setup; the port shows up as COMx or /dev/cu.usbmodem….

Configuration

--log-level LEVELSENSECA_LOG_LEVELWARNING
—SENSECA_PINnone; needed only if the instrument's protected mode is on

Auto-detection looks for USB ID 0483:5740 and only accepts a port whose device reports manufacturer senseca. If several instruments are connected, set the port explicitly; on Linux prefer the stable /dev/serial/by-id/… path.

Only one program can use the serial port at a time. Close ProXware or terminal programs while the server is running.

Measurement notes

  • Instrument accuracy: ±0.05 °C or ±0.06 % of reading (whichever is higher) ±1 digit, probe not included.
  • The USB port is not galvanically isolated. With a probe touching a grounded medium, the USB connection can shift the reading. Compare readings with and without USB, and use a USB isolator if they differ (see the instrument manual, section 7.2).

Development

bash
uv syncuv run pytest                                   # tests use a simulated instrumentnpx @modelcontextprotocol/inspector uv run mcp-server-senseca-pro   # try the tools interactively

To check a real instrument, connect it and run:

bash
uv run python scripts/hardware_test.py               # read-only checks, no interactionuv run python scripts/hardware_test.py --reconnect   # also unplug/replug USB when asked

The script only sends read commands. See --help for the PIN test.

The serial protocol is described in docs/protocol.md.
