LSN50V2 - Waterproof Wireless Node

New customers will enjoy 60-Day's FREE access on Telemetry2Us' IoT Platform. Read more here...

The LSN50 V2 is an IP68 waterproof LoRaWAN node with an external antenna to reach extremely long ranges. This version is not supplied with a sensor, allowing users to customise their own sensor configurations for custom applications. With the pre-fitted cable gland and onboard Terminal Blocks, sensor installation is simple. It runs on an open source platform, with all design files available for reference and modification. The pre-loaded firmware has multiple running modes and input types that include; ADC's, I2C, digital inputs with interrupt and a counting input and supports many existing sensors.

*** Please note that items purchased from the store only include e-mail support. The configuration and installation is the users’ responsibility. If you require a higher level of support please contact sales for a quote on premium services.

The LSN50 is a long range LoRaWAN node that provides spread spectrum communication and high interference immunity whilst minimising power consumption. Its IP68 waterproof design makes it suitable for outdoor use and its powered by a 4000mA Li/SOCl2 non-rechargeable battery. Due to its low power operation, users can expect years of operation with a moderate logging rate. 

With a variety of different inputs, the LSN50 is compatible with many sensors out of the box, including, SHT20 Temperature and Humidity sensor, HX711 load cell, LIDAR-Lite V3HP distance sensor, ultrasonic sensors, DS18B20 temperature sensors and many more with the use of the ADC’s. The LSN50 has several modes of operation to work with different combinations of sensors, listed below; 

  • MOD1 - 1 x DS18B20, 1 x Digital Input & Interrupt, 1 x ADC and 1 x SHT20 (default).
  • MOD2 - 1 x DS18B20, 1 x Digital Input & Interrupt, 1 x ADC, 1 x LIDAR-Lite V3HP
  • MOD3 - 3 x ADC’s, 1 x Digital Input & Interrupt, 1 x ADC and 1 x SHT20
  • MOD4 - 3 x DS18B20, 1 x Digital Input & Interrupt and 1 x ADC
  • MOD5 - 1 x DS18B20, 1 x Digital Input & Interrupt, 1 x ADC and 1 x HX711 Load Cell
  • MOD6 - 1 x DS18B20, 1 x Digital Input & Interrupt, 1 x ADC and 1 x Counting Input 

The operating mode and many other settings on the LSN50 can be modified via AT commands on the serial port interface, but an FT232RL USB-TTL converter is required for this task (not supplied, but recommended).  The communications port can also be used to upload new firmware via the built-in bootloader.  Some settings can also be changed via the server, like the transmit interval and the reset command.
