5. Example Programs

The example datalogger programs measure the SI-111’s thermistor to obtain

the SI-111 sensor body temperature and measure the SI-111’s thermopile to

obtain the target-to-sensor body temperature difference.

After measuring the thermopile and thermistor outputs, the sensor body

temperature is used to reference the target temperature.

Wiring for the example programs is shown in TABLE 5-1. The actual channels

used need to be adjusted for the actual installation and application.

Coefficients used to calculate the slope (m) and intercept (b) are

specific to individual SI-111 sensors. The unique coefficients for

each individual sensor are provided on the calibration sheet

shipped with the sensor.
