Infrared array sensor evaluation kit promotes IoT use

September 02, 2015 // By Julien Happich
Panasonic Automotive & Industrial Systems is launching a Grid-EYE Infrared (IR) Array sensor Evaluation Kit that combines the company's nanopower PAN1740 Bluetooth Smart module and a microcontroller on one PCB.

By combining its new IR sensor technology with Bluetooth technology and software (including basic API and image processing) for IR detection of people and objects on one board, Panasonic hopes its customers will develop rapid prototypes and quickly build their own wireless sensor IoT applications.

Panasonic has developed a PC software and a smartphone app for customers to test its sensor in different ways with various applications. Based on Panasonic’s MEMS (Micro Electro Mechanical Systems) technology, Grid-EYE combines the MEMS sensor chip, a digital ASIC (I2C interface) and a silicon lens. It has 64 thermopile elements in an 8x8 grid format that detect absolute surface temperature without any contact.

Unlike conventional sensors, Grid-EYE uses a patented 60° silicon lens etched out of a silicon wafer, which is (with less than 0.3mm height) the smallest available lens in the market. The combination of these modern and sophisticated technologies from Panasonic enables to reduce the sensor package size to only 11.6x8x4.3mm, around 70 % smaller in size than competing products.

Compared to pyroelectric sensors, it is not only possible to detect moving people and objects but also the position and presence of motionless people and objects, the direction of movements and the accurate surface temperature from -20°C up to +100°C.

The 9.0x9.5x1.8mm Bluetooth module in the evaluation kit, PAN1740 (P/N ENW89846A1KF) is a single-mode Bluetooth Smart system-on-chip module optimized for low power (only 4.9mA in transmit or receive). The SMD component benefits from a fully shielded case, chip antenna, and integrated crystal oscillators.
