Detailed Description

• ID: tmp006
• Name: TMP006 IR-Thermopile Sensor
• Category: temp
• Manufacturer: ti
• Link: http://www.ti.com/product/TMP006/datasheet/abstract#SBOS5183423
• Connection: i2c

Description in web-link above: The TMP006 and TMP006B are fully integrated MEMs thermopile sensors that measure the temperature of an object without having to be in direct contact. The thermopile absorbs passive infrared energy from an object at wavelengths between 4 um to 16 um within the end-user defined field of view. The corresponding change in voltage across the thermopile is digitized and reported with the on-chip die thermal sensor measurement through an I2C- and SMBus-compatible interface. With this data, the target object temperature can be calculated by an external processor. The Infrared thermopile sensor is specified to operate from -40 to +125 [degC]. It is possible to measure an object temperature beyond the device operating range as long as the device itself does not exceed the operating temperature range (-40 to +125 [degC]).

    std::cout << "Initializing test-application..." << std::endl;

    // please make sure that you have the right i2c address for your device
    // the correct range of addresses is 0x40 - 0x47
    // Instantiate an TMP006 instance on bus 1
    upm::TMP006 mySensor(1, TMP006_CONFIG_CR_DEF, TMP006_I2C_ADDRESS);

    // you can also get basic tmp007 functionality by initializing it as follows
    // upm::TMP006 mySensor(1, TMP006_CONFIG_CR_DEF, TMP007_I2C_ADDRESS);

    // activate periodic measurements
    mySensor.setActive();

    // update and print available values every second
    while (run) {
        // Print out temperature value in *C
        std::cout << "Temperature: " << mySensor.getTemperature(true) << " *C" << std::endl;

        upm_delay(1);
    }

    std::cout << "Exiting test-application..." << std::endl;

Member Function Documentation

int checkID

(

void

)

Check device_id of sensor

Returns

0 on succes -1 on error

Here is the caller graph for this function:

void resetSensor

(

void

)

Performs a soft reset of the TMP006 device to ensure it is in a known state.
