Hello all,

I'm Tan Do, founder and CEO of AGRHUB. I want to find a talent electronic engineering to develop a BLE 4.2 pH, EC and water level sensor.

This sensor will be integrated into our smart hydroponic system. Our gateway will connect to this sensor to get the state of hydroponic water tank as pH, dissolved oxygen (DO), oxidation-reduction potential (ORP), conductivity (salinity), turbidity, temperature and dissolved ions (Fluoride (Fluoride (F-), Calcium (Ca2+), Nitrate (NO3-), Chloride (Cl-), Iodide (I-), Cupric (Cu2+), Bromide (Br-), Silver (Ag+), Fluoroborate (BF4-), Ammonia (NH4), Lithium (Li+), Magnesium (Mg2+), Nitrite (NO2-), Perchlorate (ClO4), Potassium (K+), Sodium (Na+), water level and battery of sensor via GATT protocol.

The sensor uses a coil battery and works over one year.

Shape and size of sensor like this sensor [login to view URL]

Thanks,

Tan Do.
