Panasonic aims IR chip eval kit at Iphones with new App
The data from the Grid-EYE evaluation kit (integrating a Grid-EYE sensor, a nanopower PAN1740 Bluetooth Smart module and a microcontroller) consists of 64 pixels temperature values which correspond to the 8×8 pixels of the Grid-EYE sensor.
The 64 pixel IR camera comes in an SMT package only 11.6x8x4.3mm and detects absolute surface temperature without any contact. The PAN 1740 Bluetooth module only draws 4.9mA in transmit or receive operating modes, which means it can be powered by coin cell batteries. An Android App is currently being developed.
The Grid-EYE App complements the sensor with several features, such as temperature colour adjustment, interpolation, camera overlay, grid transparency, and camera grid ratio.
The Temperature Colour Adjustment lets users change the colour settings to make maximum use of the App in different environments. For example if the “Minimum Temperature Colour” is set to 25°C then the display colour of the pixel on the smartphone screen below this temperature value will be blue. In the same way, if the “Maximum Temperature Colour” is set to 30°C, then the display colour of the pixel on the smartphone screen above this temperature value will be red. In between 25°C and 30°C the colour of pixels will be varied between blue and red based on the colour spectrum.
The Interpolation feature will show a rough thermal image of the object being projected in front of the Grid-EYE sensor, by simply taking the 64 pixels temperature data and applying the interpolation function to display the thermal image on the smartphone.
The Camera mode (when the camera is switched on) overlays the 64 pixels of the Grid-eye sensor over the image taken by the camera. This means if the camera and the sensor both are aligned very close together and focused on an object, the thermal image formed by the pixels should be roughly equivalent to the outline of the same object seen in the camera.
Grid Transparency is used to adjust the transparency of the screen for the pixel colours and is needed especially when using with the camera overlay.
The Camera Grid Ratio mode adjusts the size ratio between the sensor grid and the camera image (in case the camera is active). The camera zoom is changed accordingly.
