power –on reset: reset circuit that starts the digital system in a known state
whenever the supply voltage is cycled
Power Supply Rejection Ratio: Measure for an amplifier’s immunity to
disturbances on the supply connections.
See Thermistor.
Serial Peripheral Interface. Commonly used 4 wire serial link to connect different
circuits over a short distance.
The temperature of the IR sensor.
Temperature dependant resistor. Basically there are 2 types. The types
that increase their resistance with rising temperature are PTC (positive
thermal coefficient) type. The ones that decrease their resistance with
rising temperature we call NTC (negative thermal coefficient) type. The
MLX90313 can work with both types.
commonly used terms in infrared thermometry. It refers to the temperature of the
target, at which the IR sensor is “looking”
