Based on Panasonic’s advanced MEMS technology, Grid-EYE features 64 thermopile elements in an 8 x 8 grid format. The combination of a built-in thermistor and an integrated circuit (IC) enables temperature sensing in a small Surface Mount Technology (SMT) package, measuring just 11.6 x 4.3 x 8.0 mm.
Unlike conventional single thermopile or pyroelectric sensors that only measure temperature at a certain point-of-contact, Grid-EYE enables contactless temperature detection over the entire specified area. Grid-EYE can use passive infrared detection to determine temperature differentiation allowing it to detect multiple objects simultaneously. It is able to measure actual temperature and temperature gradients, providing thermal images and identifying the direction of movement of people or objects.
The device’s 64 pixel range yields accurate temperature sensing, within the range of -20 to 100°C, over a viewing angle of 60° provided by a silicon lens. It uses an external I²C communication interface, enabling temperature measurement at speeds of 1 or 10 frames/sec. An interrupt function is also available. The operating voltage of the device is 3.3 V or 5.0 V.
Grid-EYE is ideal for use in a wide range of applications including consumer goods, industrial automation, security systems, digital signage, movement sensing, and healthcare devices.
The new Grid-EYE thermopile array sensor is available to purchase from Avnet Abacus.
