Agromon smart agriculture wireless transmitter connects ModBus RS485 sensors to WiFi, LoRaWAN, Sigfox, or NB-IoT

Agromon ESP32 smart farming transmitter

The Internet of Things has many applications including smart agriculture . A few months ago, I talked to a local shrimp farm owner who used Arduino and ESP8266 boards to monitor water and activate pumps only when needed to get shrimps healthy and save on his electricity bill. He built his own solutions, but there are also companies offering easy-to-use smart farming solutions such as Malaysia-based Wondernica’s Agromon “interface wireless transmitter” designed specifically for smart agriculture applications. Agromon has two variants with support for 2 sensors (WR-AGRO-2S) or 3 sensors (WR-AGRO-3S) that share the following specifications: Connectivity – WiFi, Sigfox (RCZ 2/4), LoRaWAN, NB-IoT Sensor Interface – Modbus RS485 (analog input / 4-20mA / 12V-14V output) Power Supply – 12V DC (tolerance up to 14V); supports batteries, solar power, or power adapter Power Consumption – Sleep Mode: 3 mW Dimensions – 130 x 90 x 40mm Ingress Protection – IP67 […]

Calliope 2 – An LTE Cat-1 IoT platform with VoLTE support

Calliope 2 Chip

We have already seen Sequans’ Low Power LTE-M/NB-IoT Module – the Monarch 2. Sequans, popular for its product portfolio based on Monarch LTE-M/NB-IoT and Calliope Cat 1 chip platforms, has continued to release more products with the latest announcement of the Calliope 2 LTE Cat-1 Platform (Chip). This solution is designed for IoT applications that require a higher data rate of more than 100 kilobits per second. One of the key elements of the IoT industry is to choose a network connection that is cost-efficient and provides excellent coverage along with global coverage that enables roaming and voice over LTE (VoLTE) made possible with Cat 1.  Why having audio and voice for IoT applications you may ask? That’s mostly useful in machine-to-human and human-to-machine communications such as command, control, and alerts. “Calliope 2 complements our Monarch 2 LTE-M/NB-IoT product family and makes Sequans a one-stop-shop for virtually all IoT applications—ranging […]

Year 2020 in review – Top ten posts and stats

CNX Software Year 2021

It’s this time of the year when we look back at what happened, and what may be next. 2020 did not pan out as planned in more ways than one, but there were still some interesting developments. Based on 2019 announcements, 2020 was promising to be an exciting year for Amlogic and Rockchip with the expected launch of RK3588 and S908X high-end processors for 8K capable devices,  but we’ll have to wait for 2021 for this to happen. Instead, the most interesting processor of the year from the Allwinner, Amlogic, and Rockchip offerings was probably Amlogic S905X4 processing adding AV1 hardware decoding. As pointed out in our “RISC-V 2020 highlights” post, it was a fairly eventful year for RISC-V architecture, although there’s still a long road ahead, especially for application processors. We had seen some general-purpose and Bluetooth RISC-V MCUs in 2019, but 2020 saw the launch of the first […]

Actinius launches nRF9160 SoM and XBee module with NB-IoT, LTE Cat-M, and GPS

Notecard LTE Cat-M / NB-IoT M.2 modem sells for $49+ with 10 years of connectivity

Notecard LTE Modem

If the IoT is ever going to take off, it needs low-cost hardware and connectivity. LoRaWAN is free, apart from the hardware costs, but for projects that need wider coverage and/or higher bitrate cellular connectivity is the way to go and we’ve seen in the past that Hologram offers a free developer SIM card for global IoT projects plus some low-cost cellular IoT plans, as well as 1CNE plans to offer a 10-year plan for 10 Euros. Blues Wireless has taken a different approach as they combine hardware and cellular connectivity with their Notecard LTE-IoT modems (LTE Cat 1/Cat M or NB-IoT) shipping for 10 years of connectivity for up to 500MB data. Notecard has four variants with the following key features and specifications: MCU – Arm Cortex-M4 MCU with 2MB flash Cellular connectivity NOTE-NBGL-500 – Narrowband Cat-M/NB-IoT/GPRS (Global) via  Quectel BG95-M3 modem NOTE-NBNA-500 – Narrowband Cat-M/NB-IoT (North America) via […]

Sequans Monarch 2 GM02S LTE IoT module is “5G-ready” for “Massive IoT”

Monarch 2 GM02S 5G-Ready Massive IoT

A couple of days ago, Sequans published a press release announcing the availability of Monarch 2 GM02S “5G-ready” LTE-M/NB-IoT module with power consumption further reduced by 60 percent, featuring an GSMA-compliant integrated SIM (ieUICC), and designed for “Massive IoT” applications. Wait… What is “Massive IoT”? Ericsson explains: Massive IoT refers to applications that are less latency sensitive and have relatively low throughput requirements, but require a huge volume of low-cost, low-energy consumption devices on a network with excellent coverage. The growing popularity of IoT use cases in domains that rely on connectivity spanning large areas, and are able to handle a huge number of connections, is driving the demand for massive IoT technologies. I see… That’s what I used to call LPWAN (Low-power wide-area network) applications, but for sure “Massive IoT” sounds much more cool. Monarch 2 GM02S Let’s go back to the module with Sequans Monarch 2 GM02S key […]
