with iMETOS®sm all relevant agriculture weather data are measured permanently and sent to the internet climate data base every two hours.
The iMETOS®sm station is powered by rechargeable batteries and a solar panel therefore no changing or external charging of batteries. iMETOS®sm only needs a valid GPRS contract with good GSM coverage in the area and a deactivated sim lock to be operational.
iMETOS®sm reports its data every hour to the internet climate data base. Your internet browser and your log in password to the site will get you online to data, reports and graphs observed in your own orchards or fields.
This site reserves you also an area where you can input and change the thresholds (based on phenological progress) and telephone numbers (men on duty) to be used for warnings.
