Agromon smart agriculture wireless transmitter connects ModBus RS485 sensors to WiFi, LoRaWAN, Sigfo
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
Agromon transmitter is powered by an an ESP32-WROOM-32 WiFi (and Bluetooth) module according to a recent post on Espressif Systems. WiFi connectivity would typically be used in a green house, and LPWAN standards like Sigfox, LoRaWAN or NB-IoT in the field where longer range, and solar/battery power are usually necessary.
Wondernica provides various IP68 rated sensors from an easy, plug-and-play setup, including soil sensors (pH, moisture and temperature, electrical conductivity sensor, salinity) sensors, water sensors (pH, dissolved oxygen, ammonia, turbidity, salinity, etc..), as well as radar, ultrasonic & pneumatic level meters.
Windernica also offers accessories to power the solution including a waterproof 6,600 mAh battery pack, and a solar power system with 30W panel and charge controller.
Sadly there’s no clear information about software, but I suppose farmers would just use the dashboard from their gateway and network provided to gather data in the cloud as needed.
