Agricultural wireless sensor network
development and applications
IT makes
Ubiquitous & Automatic
▪ ICT and wireless technique development
▪ Measurement instrument getting smaller, modular,
networked, wireless, economic, and low power
consumption
▪ Wireless communication
▪ 802.11, Bluetooth, ZigBee or GSM
▪ Wireless sensor network (WSN)
▪ Distributed multi-channel remote monitoring and data
collecting time-shearing system

Price vs. performance:
agricultural wireless sensor network
▪ Crossbol: integrated commercial product
▪ Field-Server: performance & functions developing with
software, sensors, camera, wireless, even solar power
▪ Sensor module: web-AD/IO card, temperature, humidity,
sunlight, CO2, ammonia, moisture content, meteorological
sensors
▪ Wireless comm.: 802.11a/b/g AP
▪ Vision: CCD, CMOS, IR-camera
▪ Power consumption: low

Wireless communication
▪ 802.11b/g：Wireless internet infrastructure, laptop
▪ Support TCP/IP、Ethernet, usually 2.4GHz
▪ 802.11b/11Mbps、802.11g/54Mbps, speed 1Mbps transmission
distance about 570 meter
▪ Router/Bridge types
▪ IEEE802.15.4 (ZigBee) : home set, PC, game box, toy
▪ 2.4GHz, 868MHz (European), 915MHz (US)
▪ Transmission distance about 75 meter, 20kbps～250kbps
▪ Low power consumption
▪ IEEE802.15.1 (blue tooth): m-phone, printer, medical equipment
▪ Short distance, 2.4GHz
▪ GPRS: bandwidth up to 160 Kbps
▪ Criteria: bandwidth, accessible, long term cost, technique popularity,
experience

Food safety system issue:
Agriculture information input

Farmers and operators to use computers is
difficult



Farmer need information but computer, farmer
earnest about profit but troublesome computer
learning
SOP？Tables？Manually？Static information？
Field server provides

Automatic, dynamic, intelligent able agriculture
data collection
19
Example: Food safety issue
▪ Transparent superintend: safety and quality
check by consumer, impartial third party,
inspector in regularly, remote, routine basis
