Application Examples

• Ambient / environmental temperature (note however that the sensor is not weather proof)
• Body temperature: touching or breathing on the sensor for example (this yields the best results when the temperature sensor is used in conjunction with our T200 Scaler).

Application Notes

• The temperature sensing component used in this device is actually capable of a larger temperature range. This sensor has been designed to focus on a smaller range to improve resolution in that range, but the sensor may be customized if the larger range is required.
