The ThermalEye board can be used as a platform for the rapid development of new intelligent systems and IoT applications. Possible applications include:
- Presence detection and abnormal behaviour detection for automatic control of functions such as lighting, climate control and safety alarms. Presence detection with low resolution thermal imaging protects users’ privacy.
- Remote monitoring of safety on equipment such as chargers, batteries, fuses, high performance equipment and kitchen appliances where there is a risk of overheating.
- Preventive maintenance
- Remote temperature measurement of heated objects in a kitchen or in an industrial process
The development platform is based on an Arduino-compatible thermal imaging shield. This shield board contains the MLX90640, a Melexis infrared sensor with an array of 32 x 24 IR-sensitive pixels. It also features a pyroelectric Panasonic PaPIR infrared sensor.
The output signals of the thermal imaging board are transferred via an I2C interface to an edge computing board with the i.MX RT crossover processor from NXP Semiconductors. The i.MX RT1050 or RT1060 runs driver software for the MLX90640 and PaPIR sensors as well as for a Tianma 4.3″ LCD color monitor.
Together with the Edge Computing Board, Future Electronics provides examples of thermal imaging application code. The easily scalable system builds on the popular Arm MBED operating system, which provides connectivity, security and real-time control capabilities. The high processing power of the i.MX RT1050/60 allows the thermal image processing and presence detection functions to be performed locally. This avoids the delays and bandwidth consumption of cloud computing architectures while allowing operators to protect user privacy.
The Melexis MLX90640 non-contact measures temperatures from -40°C to 300°C with an accuracy of ±1°C. It has a standard TO39 package with four ports.
The THERMALeye board will be available to selected Future Electronics customers in the first quarter of 2019.
