WMO accurately specifies the requirements sensors have to meet in order to be considered professional met equipment. These requirements go far beyond conventional applications like agriculture. Beyond the pure sensor specs WMO also specifies sampling and storage intervals and the rules for averaging. Data loggers must therefore offer a high degree of flexibility in their programming options, and have interfaces for a wide variety of sensor outputs. But it's also of the utmost importance that data is not only stored and infrequently read, thus reducing its value to only be of historic interest. Data much rather needs to be available in almost real time and reliably be transmitted to a central station, where it's processed and distributed.

The Adcon advantage
Adcon offers both - adequate data loggers and reliable and frequent data transmission. Take a look at the A740 addNODE - it was developed for the task! Lots of I/Os, each of which can individually be programmed and sampled, V and mA inputs, frequency, TTL and pulse counters, even TTL, analog and PWM outputs. Its integrated radio modem sends data back to base in short intervals.

Adcon's radio technology
Building large networks, covering huge areas, is Adcon's core expertise. You can choose the right UHF RTU for every task, from short range addIT's to long range addWAVE's all the way to a quad-band GSM/ GPRS RTU. UHF technology offers several advantages over cellular technology, the most obvious being its lower operational cost and its lower power consumption. Particularly in areas with bad GSM coverage it also makes you independent from public infrastructure. Although output power is no higher than 500mW, our networks can achieve large diameters, since every long range measuring station can act as a relay at the same time, thus making direct connection to the base obsolete. Where GSM coverage is satisfactory, and good data plans are available fro your provider, a GPRS option is at hand.
Power typically comes from an integrated battery pack, which is charged by a very small solar panel. However, heated sensors still require external power sources, like mains supply or larger battery packs.

Sensors
Adcon supplies a series of professional sensors for this application. But since we are the experts for the radios, we choose the respective experts for these sensors, closing OEM and distribution agreements with well respected manufacturers of highly professional equipment, such as Vaisala of Finland, whose combined temperature and humidity sensors we use, and Kipp & Zonen, world leader in solar radiation instruments.
