The TMP117 is a high precision temperature sensor that communicates over I²C. Each sensor is tested on a NIST tracable test setup during Texas Instruments' production process. Accuracy should be at worst 0.1C across the -20C to +50C temperature range.
|
|
|
|
To use the sensor, first set up an :ref:`I²C Bus <i2c>` and connect the sensor to the specified pins.
|
|
|
|
If accuracy is a must, see section 8.2.2.2 of the `datasheet <https://www.ti.com/lit/ds/symlink/tmp117.pdf>`__.

# Example configuration entry
|
|
sensor:
|
|
- platform: tmp117
|
|
name: "Living Room Temperature"
|
|
update_interval: 60s
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **address** (*Optional*, int): The I²C address of the sensor.
|
|
See :ref:`I²C Addresses <tmp117_i2c_addresses>` for more information.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``. The sensor component sets the maximum possible averaging in the sensor based on this.
|
|
- All other options from :ref:`Sensor <config-sensor>`.

I²C Addresses
|
|
-------------
|
|
|
|
In order to allow multiple sensors to be connected to the same I²C bus,
|
|
the creators of this sensor hardware have included some options to
|
|
change the i²c address.
|
|
|
|
- If the address pin is pulled to GND, the address is ``0x48`` (Default).
|
|
- If the address pin is pulled to VCC, the address is ``0x49``.
|
|
- If the address pin is tied to SDA, the address is ``0x4A``.
|
|
- If the address pin is tied to SCL, the address is ``0x4B``.
