dfrobotstcc4i2c

Use this skill when the user asks to detect or read Sensirion STCC4 CO2 concentration (ppm). This sensor readout also includes temperature and humidity.

Typical Chinese requests:

• 帮我检测一下 STCC4 的 CO2 浓度
• 读取 STCC4 的二氧化碳浓度
• 看一下 STCC4 的空气质量
• 读取 STCC4 的温湿度和 CO2

Typical English requests:

• Check STCC4 CO2 concentration
• Read STCC4 CO2 ppm
• Measure air quality with STCC4
• Read STCC4 CO2, temperature, and humidity

Run exactly one bundled Lua script with lua_run_script.

  "type": "object",

Tool Call Inputs

{"path":"{CUR_SKILL_DIR}/scripts/read_sensor_data.lua","args":{"action":"read"}}

Use explicit address 0x64 and CRC verification:

{"path":"{CUR_SKILL_DIR}/scripts/read_sensor_data.lua","args":{"action":"read","addr":100,"verify_crc":true}}

Start continuous measurement only:

{"path":"{CUR_SKILL_DIR}/scripts/read_sensor_data.lua","args":{"action":"start"}}

Stop continuous measurement only:

{"path":"{CUR_SKILL_DIR}/scripts/read_sensor_data.lua","args":{"action":"stop"}}

Recommended Flow

1. Confirm sensor wiring and I2C address.
2. If user does not provide address, use STCC4 default address 0x64.
3. Run {CUR_SKILL_DIR}/scripts/read_sensor_data.lua with action = "read" to get one sample.
4. Use start and stop actions only when user explicitly asks to control measurement state.
5. Report script output directly.
