  • Automation and mmonitoring improves yields 2-3 times compared to manual tapping while dramatically reduce the risk of injury to workers

China, September 17, 2021 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, announced a design contract for STM32WLE5 *, the world’s first LoRa system on a chip (SoC). The client application, developed by the specialist in automated tapping CIHEVEA, uses the low consumption network to revolutionize the automation of latex extraction from rubber trees. CIHEVEA has equipped more than 200,000 rubber trees on its Hainan rubber plantation with its innovative solution to improve productivity and bleeding production capacity.

The ST LoRa SoC acts as a highly efficient and low power communication hub and control center for CIHEVEA’s rubber tapping robot. The robot also includes two precision motors and a series of environmental sensors that monitor weather conditions, including temperature, air pressure, and humidity. Attached to the tree, the STM32WLE5 transmits data from the sensors to a mesh gateway via a dedicated LoRa application network server, where the server can monitor, test and debug, and coordinate robots in the field. Once all of the pre-set conditions are met, the SoC triggers the rubber tapping motors to perform a stand-alone cut, which usually occurs very early in the morning.

Leveraging cost-effective and high-efficiency STM32WLE5 and LoRa networks, CIHEVEA’s new solution increases latex yield 2-3 times while minimizing tree damage, thereby extending the productive life of trees. In addition to improving yields and extending asset life, the rubber tapping robot also solves chronic labor issues, as tapping trees can be difficult and dangerous for workers. humans.

The STM32WLE5 is an ultra-low power, multimodulation wireless SoC microcontroller that combines an Arm® Cortex®-M4 core operating at 48 MHz, a sub-GHz radio for long-range connectivity and a proven collection of peripherals designed by ST. Delivering high performance while operating from an enclosure as small as 5mm x 5mm (UFBGA), the STM32WLE5 is both cost effective and meets the ruggedness and performance demands of the agricultural industry. The STM32WLEx microcontroller is also an open platform supporting LoRa®, (G) FSK, (G) MSK and BPSK modulations.

“The fully automatic and intelligent tapping system is a revolution for the rubber industry. With the increased use of platform technology and the ability to communicate via the low power LoRa network technology provided by the STM32WLE5, smart rubberplanting platform system is to createis lying a new rubberplantation ecosystem, moving away from the traditional high intensity, heavypollution, inefficient, manufacturing methods and is ushering in a new era of the green environmentprotection, highefficiency, digital transformation ”, said XU Zhen Kun, vice president of CIHEVEA.

While rubber trees are a sustainable source of an important material widely used in industry, transportation and agriculture, Improis lying rubber thread Efficiency, and increasesis lying latex yield has long been a goal of rubber producers and the use of the STM32WL5 and its LoRa networking is a natural choice ”, said Arnaud Julienne, Vice-President, Microcontrollers and Digital Integrated Circuits Group, IA / IoT and Digital Marketing Competence Center, Asia-Pacific Region, STMicroelectronics. “In addition, our unique and large portfolio of products and solutions in connectivity, detection, and large power portfoliomanagement and enginecontrol solutions is well suited To the full range of smart agriculture domains, including monitoring, irrigation systems, tractors, and livestock position and health monitoring.
