2.2.5 Analog temperature sensor
The device supports 2 different sensors: LM35DZ and MCP9701. In both of them, the output
signal should be connected to the
AT terminal. The reference is GND . Regarding power supply
to the sensor, the LM35DZ can be powered using terminals V+ and GND , while MCP9701 can
be powered using terminals 3V3 and GND . To choose between the two, you have to access the
IO configuration page. Please consult section 3.3.
When not in use, this feature should be disabled, in order to prevent erroneous behavior.
Please consult section 3.3.
2.2.6 Analog output
The analog output is connected to AO terminal. The reference is GND .
2.2.7 Relative humidity and Temperature sensor
IO.XEC supports Sensirion SHT75 RH and temperature sensor. Please consult the sensor
datasheet. The terminals to use are
SDA , SCL , 3V3 , GND .
When not in use, this feature should be disabled, in order to prevent erroneous behavior.
