X. DAT5280 Ambient Temperature Sensor Module
X.1 Introduction
The DAT5280 Ambient Temperature Sensor Module uses high-precision CMOS temperature sensor
to generate linear voltage signal according to the ambient air temperature. With a temperature
coefficient of 25.5 mV/˚C and nonlinearity of ±0.5 %, the DAT5280 is superior in the functionality
over conventional temperature sensors like thermometers. Typical applications include robotic system
and high-precision thermal control.
X.1.1 Features
• High linearity: ± 0.5%
• Standard output: 0 – 3.3V
• High temperature accuracy
• Plug-and-play in the WiRobot system
X.1.2 Applications
• Robotic system
• Temperature sensing
• Thermal control
X.2 Operations
X.2.1 Typical performance characteristics
The performance characteristics are shown in the figures X.1 and X.2. If needed, the temperature
accuracy error could be removed by calibration on the individual module basis.
