38K Infrared Data Logger
MC11-38K Infrared Data Logger
MC11 is a high-performance, low-power infrared communication acquisition terminal independently developed by ManThink. The product integrates 38kHz infrared signal transceiver module, high-performance MCU and LoRa ® RF chip, flexible configuration, designed for all kinds of equipment with 38kHz infrared interface to achieve data acquisition and remote control and design.
Based on advanced LoRa ® Wireless technology, MC11 support standard LoRaWAN ® Protocol, with ultra-long communication distance and ultra-low power consumption, suitable for wide-area IoT deployment. The equipment adopts adhesive mounting design, equipped with 3V battery interface and external AA battery box (supporting 2 5th batteries), which is convenient to install and has long endurance.
MC11 compatible with mainstream LoRaWAN ® Gateways and IoT platforms (such as ThinkLink, ChirpStack, and The Things Network) can seamlessly connect to existing IoT systems to achieve efficient cloud migration and centralized data management.
The built-in EB virtual machine supports compiling EB scripts and remotely updating device functions through FUOTA (Firmware Over-the-air upgrade). With the help of EB virtual machine, users can quickly adapt to the infrared communication protocols of different manufacturers, and realize complex business logic such as data filtering, COV (change reporting), alarm triggering, data reorganization, etc. on the terminal side, which greatly improves the flexibility and intelligence level of the system.
