DescriptionThe ThermalOnline Cat-M is an industrial-grade thermal monitoring kit for remote, non-contact temperature detection. It combines an MLX90640 thermal sensor, M5Stack BASIC ESP32 control, and a SIM7080G Cat-M/NB-IoT communication module, while Wi-Fi remains available through the core controller. The ThermalOnline Cat-M thermal monitoring kit supports Cat-M, NB-IoT, and Wi-Fi communication, and its base exposes I2C, UART, GPIO, RS485, DC input, and battery interfaces for sensor expansion. This MLX90640 thermal sensor solution is built for remote monitoring, automation, and data acquisition where a compact CAT-M thermal monitoring kit is easier to deploy than a separate camera, controller, and modem.Features ThermalOnline Cat-M thermal monitoring kit for non-contact temperature detection. MLX90640 thermal sensor with 32 x 24 infrared pixel array and -40°C to 300°C range. SIM7080G communication module supports Cat-M and NB-IoT dual-mode wireless networking. MicroSIM card slot and external SMA antenna for cellular deployment. M5Stack BASIC controller provides ESP32 control and Wi-Fi capability. Expansion interfaces include I2C, UART, GPIO, RS485, DC input, and battery connection. ThermalOnline Cat-M includes DIN rail mounting hardware for fixed monitoring setups.
