31 The SHT10, SHT11, SHT15, SHT71, and SHT75 are humidity and temperature
34 The devices communicate using two GPIO lines.
36 Supported resolutions for the measurements are 14 bits for temperature and 12
37 bits for humidity, or 12 bits for temperature and 8 bits for humidity.
39 The humidity calibration coefficients are programmed into an OTP memory on the
40 chip. These coefficients are used to internally calibrate the signals from the
41 sensors. Disabling the reload of those coefficients allows saving 10ms for each
42 measurement and decrease power consumption, while loosing on precision.
44 Some options may be set directly in the sht15_platform_data structure
45 or via sysfs attributes.
47 Note: The regulator supply name is set to "vcc".
53 flag to indicate not to reload from OTP (default to false).
55 flag to indicate the temp/humidity resolution to use (default to false).
60 * temp1_input: temperature input
61 * humidity1_input: humidity input
62 * heater_enable: write 1 in this attribute to enable the on-chip heater,
63 0 to disable it. Be careful not to enable the heater
65 * temp1_fault: if 1, this means that the voltage is low (below 2.47V) and
66 measurement may be invalid.
67 * humidity1_fault: same as temp1_fault.
