Armando Visconti 87d6c50e47 sensors: Add separation between ambient and die temperature Some device include a temperature sensor, usually used as a companion for helping in drift compensation, that measure the die temperature. This temperature IS NOT related to the the ambient temperature, hence a clean separation between the two is required. This commit introduces a clean separation between the two types of temperature leaving the old deprecated definition still there. The list of current drivers that read the die (and not the ambient) temperature is the following: - adxl362 - bma280 - bmg160 - bmi160 - fxos8700 - lis3mdl - lsm6ds0 - lsm6dsl - lsm9ds0 - mpu6050 Signed-off-by: Armando Visconti <armando.visconti@st.com>		2018-04-03 22:29:11 -04:00

TH02: Temperature and Humidity Monitor
######################################

Overview
********
This sample periodically reads temperature and humidity from the Grove
Temperature & Humidity Sensor (TH02) and display the results on the Grove LCD
display.


Requirements
************

This sample uses the TH02 sensor and the grove LCD display. Both devices are
controlled using the I2C interface.

More details about the sensor and the display can be found here:

- `Grove Temperature And Humidity`_
- `Grove LCD Module`_

Wiring
******

The easiest way to get this wired is to use the Grove shield and connect both
devices to I2C. No additional wiring is required. Depending on the board you are
using you might need to connect two 10K ohm resistors to SDL and and SDA (I2C).
The LCD display requires 5 volts, so the voltage switch on the shield needs to
be on 5v.
