:name: Grove Temperature Sensor
|
|
:relevant-api: sensor_interface
|
|
|
|
Get temperature data from a Grove temperature sensor and display it on an LCD display.
|
|
|
|
Overview
|
|
********
|
|
|
|
This sample application gets the output of the grove temperature sensor and prints it to the
|
|
console, in units of celsius, once every second. When the :kconfig:option:`CONFIG_GROVE_LCD_RGB`
|
|
and :kconfig:option:`CONFIG_I2C` options are set, the temperature will also be displayed on the
|
|
Grove LCD display.
|
|
|
|
Requirements
|
|
************
|
|
|
|
To use this sample, the following hardware is required:
|
|
|
|
* A board with ADC support
|
|
* `Grove Temperature Sensor`_
|
|
* `Grove Base Shield`_
|
|
* `Grove LCD`_ [optional]
|
|
|
|
Wiring
|
|
******
|
|
|
|
The easiest way to connect the sensor is to connect it to a Grove shield on a board that supports
|
|
Arduino shields. Provide a devicetree overlay that specifies the sensor location. If using the
|
|
overlay provided for the sample, the sensor should be connected to A0 on the Grove shield. The
|
|
Grove LCD, if being used, should be connected to I2C on the Grove shield and the overlay needs to
|
|
contain an entry for it.
