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 […]
