Notes
1. Measured with AMP connectors in still air with solid copper wires
of 1 mm diameter.
2. The response time is the time necessary to change 63.2% of the
total difference between the initial and the final body
temperature, when subjected to a step function change in
ambient temperature.
Step change:
a) initial temperature: air at 25

3. The temperature gradient is the difference per degree Celsius
between the true temperature of the liquid (water) and the
temperature measured by the sensor.
