Temperature is measured in degrees 45 celsius, relative humidity is expressed as a percentage. 46 47 The device communicates with the I2C protocol. All sensors are set to I2C 48 address 0x70. See Documentation/i2c/instantiating-devices.rst for methods to 49 instantiate the device. 50 51 There are two options configurable by means of shtc1_platform_data: 52 53 1. blocking (pull the I2C clock line down while performing the measurement) or 54 non-blocking mode. Blocking mode will guarantee the fastest result but 55 the I2C bus will be busy during that time. By default, non-blocking mode 56 is used. Make sure clock-stretching works properly on your device if you 57 want to use blocking mode. 58 2. high or low accuracy. High accuracy is used by default and using it is 59 strongly recommended. 60 61 sysfs-Interface 62 --------------- 63 64 temp1_input 65 - temperature input 66 humidity1_input 67 - humidity input
