LM7X(4D) Devices LM7X(4D)
lm7x - lm75, lm76, and lm77 series I2C temperature sensor driver
/dev/sensors/temperature/i2c/lm7x*
The lm7x driver supports devices compatible with the National
Semiconductor LM75, LM76, and LM77 I2C temperature sensor devices.
Each device supports a single temperature sensor that is registered
with the kernel sensor framework and an interface to them is provided
by ksensor(4D).
The LM75 and LM77 generally measure in units of 1/2 degree Celsius
while the LM76 measures in units of 1/16th degree Celsius. Temperature
information is available to the system through the fault management
architecture (FMA). The file system location and programming interface
to the lm7x temperature sensors are considered volatile.
