Automated Multi-Feed Fertilizer Spreader
Application Overview
A major manufacturer of agricultural equipment identified a need for an automatic multi-feed fertilizer spreader. Each Individual fertilizer feed needed to be controlled independently – thus allowing the fertilizer to be spread only where and when needed. The current solution was proving to be not feasible as the moving parts were quickly wearing out the cables and thus requiring expensive field retrofits.
A wireless solution replacing the cables was deemed to be most suitable. The DNT24 was embedded with the spreader controller in the tractor cab. On the spreader side, the DNT24s were embedded with the feed valves at end of the spreader attachment. Each valve was controlled by one of the GPIOs of the DNT24 based on commands sent by the controller in the cab. No other intelligence is needed at the valve – just circuitry to interface the GPIO signal to the valve.
Applicable Product Features
The DNT24 Frequency Hopping Spread Spectrum technology(FHSS) provides reliable RF communication in moving equipment with a lot metal thus overcoming multipath fading. The DNT24 Module with multiple I/O provides activation signals for each valve without any other intelligence. The low cost allows multiple feed systems to be economically priced and finally the 2.4GHz allows world-wide deployment.
