15Description
16-----------
17
18The DS620 is a (one instance) digital thermometer and thermostat. It has both
19high and low temperature limits which can be user defined (i.e. programmed
20into non-volatile on-chip registers). Temperature range is -55 degree Celsius
21to +125. Between 0 and 70 degree Celsius, accuracy is 0.5 Kelvin. The value
22returned via sysfs displays post decimal positions.
23
24The thermostat function works as follows: When configured via platform_data
25(struct ds620_platform_data) .pomode == 0 (default), the thermostat output pin
26PO is always low. If .pomode == 1, the thermostat is in PO_LOW mode. I.e., the
27output pin PO becomes active when the temperature falls below temp1_min and
28stays active until the temperature goes above temp1_max.
29
30Likewise, with .pomode == 2, the thermostat is in PO_HIGH mode. I.e., the PO
31output pin becomes active when the temperature goes above temp1_max and stays
32active until the temperature falls below temp1_min.
33
34The PO output pin of the DS620 operates active-low.

20Description
21-----------
22
23The SHT21 and SHT25 are humidity and temperature sensors in a DFN package of
24only 3 x 3 mm footprint and 1.1 mm height. The difference between the two
25devices is the higher level of precision of the SHT25 (1.8% relative humidity,
260.2 degree Celsius) compared with the SHT21 (2.0% relative humidity,
270.3 degree Celsius).
28
29The devices communicate with the I2C protocol. All sensors are set to the same
30I2C address 0x40, so an entry with I2C_BOARD_INFO("sht21", 0x40) can be used
31in the board setup code.

39Notes
40-----
41
42The driver uses the default resolution settings of 12 bit for humidity and 14
43bit for temperature, which results in typical measurement times of 22 ms for
44humidity and 66 ms for temperature. To keep self heating below 0.1 degree
45Celsius, the device should not be active for more than 10% of the time,
46e.g. maximum two measurements per second at the given resolution.
47
48Different resolutions, the on-chip heater, using the CRC checksum and reading
49the serial number are not supported yet.
