MinewSemi Lanuches a New Long Range Low Power LoRa Transceiver Module MS21SF13 to Support Multiple Industry Applications

With the rapid development of IoT wireless communication technology, the demand for?the?module market is increasing all the time. Now, MinewSemi?is?actively?expanding?IoT?module MS21SF13 into the?Lora?market. It is a type of small-sized transceiver module, that features ultra-long range, ultra-low power,?and easy connect with different Microcontrollers through SPI Interface. The module is based on Semtech SX1262 chip(Wireless Half duplex transceiver chips), which supports global frequency ISM.

MS21SF1 Module is suitable for various application scenarios that require remote data collection and low power consumption.

What is?LoRa?

What is LoRa?? LoRa is?a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. Semtech's LoRa is a long-range, low-power wireless platform that has become the wireless platform of Internet of Things (IoT).

Key features of LoRa module

1.?LoRa connects?long range?and strong anti-interference

It can achieve transmission power up to +22dBm with higher reception sensitivity, and down to -146Bm, which through the internal integration of high-efficiency power amplifiers. Compliant with LoRaWAN physical layer requirement standard specification, it supports LoRa? P2P(per-to-per)communication, enabling customers to quickly establish private long-range LoRa ? network points.

2. Ultra-low power and stable transmission and reception

The MS21SF1 ensures a long connection distance while also achieving extremely low module power consumption. Under the receive mode, the current is only 4.7mA; under the reception mode, the current is 118mA, and the Voltage is 3.1V. When it's at the sleep mode, the highest peak value is 538.41uA, while the average power consumption is only 0.85uA. Since Semtech's LoRa? modulation technology, the MS21SF1 can?send and receive data stably even at low power consumption.

3. It supports SPI interface

SPI runs on an external SCK clock, enabling it to reach a rate of 16MHz. The transmission starts when the NSS pin level becomes low. When the NSS is high level, the MISO is in a high impedance state. The flexible SPI interface allows the MS21SF1 to be used directly with different microcontroller models.

4.?Support programmable bit rate

The module supports programmable bit rates, including LoRa and FSK modulation at up to 62.5 kbps and 300 kbps respectively, making it easy for users to perform secondary development.

The Application Scenarios of LoRa Modules

Smart agriculture

Smart agriculture use cases based on LoRa module MS21SF1's long-range transmission, which enables to detect the data of agricultural greenhouse temperature, humidity and CO2 concentration. With the help of MinewSemi's LoRa module, the information can be transmitted to the control and dispatching center, and then based on real-time data analysis to realize long-distance transmission, which enables to improve efficiency and reduce costs.

Environmental monitoring

By implementing a network of sensors and gateways embedded with LoRa Technology across a region,LoRa module connects?various sensors to collect data. As we all know, the traditional human monitoring can no longer meet the impact of changing environmental factors.

However, when using the MS21SF1 module, you can monitor environmental factors such as temperature, humidity, wind speed, water level, etc. for real-time data transmission to achieve the purpose of low-cost, long-distance and low-power monitoring of the environment. From air quality monitoring to radiation leak detection, LoRa?-based IoT solutions for the environment help protect citizens from environmental dangers.

Smart meters

Smart meter reading can be used for water, electricity, heat,?and other metering pumps. How does MinewSemi's lora module in the application of wireless meter reading? Our Lora module is mainly collect data by connecting water/electricity/gas meters and sending?the collected data to the gateway in turn. The gateway then transmits the data to the remote control center to realize?the?remote meter reading.

The LoRa module has the greatest advantage is low-cost, which is conducive to the construction of smart cities. LoRa wireless transmission technology makes the work of meter reading easy and reduces its cost. What's more, the received data becomes more accurate,?and low power consumption is maintained with two-way interaction.

In addition to the above applications, MinewSemi's MS21SF1 module supports lots of application scenarios, such as smart cities, industrial IoT, smart homes, smart buildings, smart utilities and smart logistics supply chain. It is worth noting that LoRa modules should be used in environments that are relatively open and with few obstructions. If the environment cannot be guaranteed to be relatively open, the obstructions between two LoRa modules in a straight line can be as small as possible.

It's because the obstructions sometimes prevent communication and narrows the distance of communication.
