As people get more health conscious about quality
of food and less and less space available for farming,
hydroponics becomes a trend for next generation
farming
Plants that grow only on water requires exceptional
water quality monitoring at a continuous level
Sensors can be used at locations to regularly
monitor water conditions with 4-20mA output
Water quality sensors with 4-20mA output
Water quality sensor list:
1. pH
2. Dissolved Oxygen (concentration
of oxygen in water for aquaponics
for fishes)
3. Water temperature
4. Salinity
5. Electro conductivity (nutrient or salt
level)
Applications include:
--
Hydroponic farm (outdoor or indoor)
-- Control shade screens, air fans, water temperature
control to maintain the right growing condition
