It depends on several factors: crop arrangement, irrigation plan, and drainage conditions; a typical farm uses:
Each Ceres Gateway supports up to 100 remote wireless devices. You can use unlimited numbers of Ceres Gateways.
Ceres integrates everything into one rugged package that includes sensors, data loggers, transmitters, and valve controllers. You don’t need a degree in electrical engineering or computer science to deploy and use Ceres; there are no wires to connect, no networks to configure, and batteries are included!
1km of real world range is a good rule of thumb.
Ceres uses narrow-band, sub-GHz, spread-spectrum technology to achieve maximum range. Common network technologies such as WiFi and Bluetooth are optimized for high bandwidth at the expense of range.
Place your gateway where its antenna is high and as close to the fields as possible. Minimize obstructions in the wireless path (walls, dense foliage, hills, etc.).
The battery in the Ceres irrigation controller powers the valve directly. No external power sources are required: there are no solar panels to maintain and no wires to run through your fields.
Ceres devices use ultra-high-density lithium batteries to provide many years of service. When deployed properly:
Ceres is designed to automate drip irrigation.
YES! Standard screen or disk filters with 150 mesh (100 micron) or higher should be used. No irrigation system should use unfiltered water.
Ceres brass and stainless steel valves are available in DN15 (NPS 1/2”), DN20 (NPS3/4”), DN25 (NPS 1”), DN40 (NPS 1.5”), DN50 (NPS 2”)
15-145psi (0.1-1MPa) for smaller valves up to 230psi (1.6MPa) for large valves. Note: pressures below 15psi (0.1MPa) can result in restricted flow.
