In many remote rural areas, modern agricultural monitoring remains a significant challenge. Poor network infrastructure, limited access to reliable power sources, and the high cost of traditional surveillance systems make it difficult for farmers to monitor crop growth, environmental changes, or potential threats in real time. These limitations often lead to reduced productivity, delayed responses to environmental stress, and an overall lack of actionable insights.
A low-power remote agricultural monitoring system was designed and implemented using the Heltec ESP32 Wi-Fi HaLow Camera, HT-7608 HaLow Gateway, and Wi-Fi HaLow Dongle, aiming to improve wireless connectivity in challenging and remote agricultural settings.
The system utilizes the HT-7608 HaLow Gateway as an access point (AP) and the Wi-Fi HaLow Dongle as a station (STA), enabling wireless communication over distances of up to 1 kilometer. By connecting the ESP32 Wi-Fi HaLow Camera to the HaLow Dongle, the system supports long-range, stable transmission of real-time visual data from the field. This ensures reliable operation even in remote areas without consistent internet connectivity, providing continuous and efficient visual monitoring of agricultural environments.
Wi-Fi HaLow, belongs to 802.11ah protocol, operates in the sub-1 GHz band, offering longer range and better penetration than traditional Wi-Fi. Its low-power design with efficient sleep and wake mechanisms extends battery life, while supporting high device density and stable connections in crowded environments, solving congestion issues of traditional Wi-Fi.
Configure HT-H7608 Wi-Fi HaLow Router as AP
Configure Wi-Fi HaLow Dongle as STA
Install Heltec Wi-Fi HaLow development framework
Open Arduino, select the development board, and find the sample code.
Note: The wiFi connected in the code is Wi-Fi HaLow Dongle's wifi.
After successfully running the example code of Wi Fi HaLow, the serial port will print the IP address.
After logging in to the IP address, you can view the real-time screen.
