# MLX90614 - Infra Red Thermometer
|
||||
|
||||
The MLX90614 is an Infra Red thermometer for noncontact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASSP are integrated in the same TO-39 can. Thanks to its low noise amplifier, 17-bit ADC and powerful DSP unit, a high accuracy and resolution of the thermometer is achieved.
|
||||
|
||||
## Sensor Image
|
||||
|
||||
|
||||
## Usage
|
||||
```C#
|
||||
I2cConnectionSettings settings = new I2cConnectionSettings(1, Mlx90614.DefaultI2cAddress);
|
||||
I2cDevice i2cDevice = I2cDevice.Create(settings);
|
||||
|
||||
using (Mlx90614 sensor = new Mlx90614(i2cDevice))
|
||||
{
|
||||
// read ambient temperature
|
||||
double ambient = sensor.ReadAmbientTemperature().Celsius;
|
||||
// read object temperature
|
||||
double object = sensor.ReadObjectTemperature().Celsius;
|
||||
}
|
||||
```
