Ports

Output

Temperature — Ambient temperature in degree Celsius

scalar

The port outputs ambient temperature that the TMP102 sensor reads in degree Celsius.

Data Types: double

Parameters

Main

I2C module — I2C communication module

1 (default) | scalar

Specify the I2C module on the Raspberry Pi^® hardware to communicate with the TMP102 sensor.

To enable the secondary I2C bus on your Raspberry Pi hardware, follow the steps as mentioned in Enable Secondary I2C Bus of Raspberry Pi Hardware.

I2C address — I2C peripheral address

0x48 (default) | 0x49 | 0x4A | 0x4B

Specify the I2C peripheral device address from which you want to read the TMP102 temperature data.

You can connect up to four TMP102 temperature sensors to your Raspberry Pi hardware. The I2C address for the sensor connection is dependent on the state of the ADD0 pin of the sensor. This table provides the I2C addresses and their corresponding ADD0 pin connection details.

Raspberry Pi Pin Connection	I2C Address
GND	0x48
VCC	0x49
SDA	0x4A
SCL	0x4B

Sample time — Time frequency

1 (default) | positive integer

Specify the frequency at which the block reads the temperature values from the TMP102 sensor.

Advanced

Temperature alert limits (^oC) — Temperature threshold limits for sensor

[16,60] (default) | scalar

Enter the minimum and maximum temperature threshold limits to generate a signal on the alert pin of the TMP102 sensor when the ambient temperature equals or exceeds the maximum threshold value.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"raspberrypienvironmentalsensorslib/TMP102 Temperature Sensor"

Example: add_block("raspberrypienvironmentalsensorslib/TMP102 Temperature Sensor","myModel/myBlock",MakeNameUnique="on")
