FAQ
It supports up to 2 valves via relay outputs. Each valve can be controlled manually, remotely via LoRa, or automatically based on water level.
The stable communication distance is approximately 150 meters in open field conditions. Actual distance may vary depending on terrain and obstacles.
Yes, it can operate in manual mode using the 6 buttons for local control, or in remote mode via LoRa commands. Water level monitoring is optional.
LoRa parameters such as frequency, spreading factor, and bandwidth can be configured via the RS485 interface using MODBUS-RTU commands.
The module accepts a wide DC input range of 9-36V, making it suitable for various power sources including batteries and solar-powered systems.
The front panel has IP51 rating, but overall rating is IP20. It is recommended for indoor or protected outdoor installations (e.g., inside a weatherproof enclosure).
Summary
The AWT200-KJBQ is a dedicated irrigation control module that brings automation to farmland water management. With LoRa wireless communication (460-510MHz), it enables remote valve control up to 150 meters away, eliminating the need for manual field visits. Six manual buttons provide local control flexibility, while two relay outputs directly drive irrigation valves. The module supports for automatic water level regulation, maintaining optimal irrigation conditions without human intervention. Its compact DIN-rail mount design, wide DC power input (9-36V), and industrial temperature range make it suitable for diverse agricultural environments. Whether used in standalone manual mode or integrated into a larger smart farming system, the AWT200-KJBQ offers a reliable, cost-effective solution for modernizing irrigation control.
