In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers.

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>
Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

New Bluetooth 5.0 modules from STMicroelectronics
13.09.2020
The new STMicroelectronics BlueNRG-M2SA and BlueNRG-M2SP radio modules are based on the BlueNRG-2 system-on-a-chip and comply with the Bluetooth 5.0 standard. The modules support multiple roles and can act as a Bluetooth master and slave at the same time. The BlueNRG-M2 radio modules are a complete RF platform including an antenna. The Bluetooth Low Energy stack and user application can run on the module.
Modules allow you to create a complete IoT product without deep knowledge in the field of high-frequency device development and significantly reduce the time to bring a new product to market. Applications for the modules include building control devices, industrial process automation, lighting control, medical equipment and security systems.
The BlueNRG-M2 can be powered directly from a pair of AAA batteries or from any 1,7V to 3,6V power source. The BlueNRG-M2 comes in two variants: BlueNRG-M2SA and BlueNRG-M2SP. They have different internal HW configurations that differ in software initialization. The BlueNRG-M2SP module is a simplified version and does not include the 32768 Hz crystal and inductance to operate the internal SMPS power converter.
Features of BlueNRG-M2SA and BlueNRG-M2SP modules:
Bluetooth v5.0 certified;
Work in Master and Slave modes;
Simultaneous support for multiple roles;
Work with increased packet length;
Embedded ST BlueNRG-2 BLE SoC;
High performance low power MCU Cortex-M0;
Programmable built-in 256 KB Flash;
RAM 24 KB with data retention in sleep modes;
Increased output power up to +8 dBm;
Receiver sensitivity up to -88 dBm;
High radio link budget 96 dB;
Built-in BALF-NRG-02D3 balun with harmonic filter;
Interfaces 1 x UART, 1 x I2C, 1xSPI, 14xGPIO, 10-bit ADC, RTC, etc.;
Chip antenna (BLUENRG-M2SA) or PCB antenna (BLUENRG-M2SP);
Ready-made Bluetooth low energy stack in the form of a library (GAP, GATT, SM, L2CAP, LL);
BlueNRG-2 SDK with sample profiles and ready-made applications;
Built-in boot via UART-bootloader;
Small dimensions 11,5 x 13,5 mm;
Supply voltage from 1,7 to 3,6 V;
Temperature range -40...85°C.
