H A Dsht3x.rst6 * Sensirion SHT3x-DIS
16 - David Frey <david.frey@sensirion.com>
17 - Pascal Sachs <pascal.sachs@sensirion.com>
20 -----------
22 This driver implements support for the Sensirion SHT3x-DIS chip, a humidity
23 and temperature sensor. Temperature is measured in degrees celsius, relative
25 scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
29 Documentation/i2c/instantiating-devices.rst for methods to instantiate the device.
31 Even if sht3x sensor supports clock-strech(blocking mode) and non-strench
32 (non-blocking mode) in single-shot mode, this driver only supports the latter.

53 - No low limit for local temperature.
54 - No critical limit for local temperature.
55 - Critical limit for remote temperature can be changed only once. We
56 will consider that the critical limit is read-only.
63 All temperature values are given in degrees Celsius. Resolution is 1.0
67 store the value in an 8-bit register and have a selectable clock divider
68 to make sure that the result will fit in the register, the LM63 uses 16-bit
72 Note that the pin used for fan monitoring is shared with an alert out
77 for fan monitoring and alert out. On the LM64, monitoring is always enabled;

23 temperature of a discrete diode-connected transistor, such as a 2N3906,
27 I2C-compatible interface. Fan speed is controlled based on the temperature
28 reading as an index to a 48-byte lookup table (LUT) containing
29 user-programmed PWM values. The flexible LUT-based architecture enables
34 shut down the system. A dedicated ALERT pin reports that either a local or
35 remote high-temperature threshold has been exceeded.
37 Temperature measurement range: from -55°C to 125°C
41 Please refer how to instantiate this driver: Documentation/i2c/instantiating-devices.rst
