Thermostat and TDS meter

THERMOSTAT
Thermostat is a device that automatically regulates temperature, or that activates a device when the temperature reaches a certain point.
Working:
Mechanical thermostats use of thermal expansion to switch an electric circuit on and and off. The two most common types use bimetallic strips and gas-filled bellows.

TDS METER
A tds Meter indicates the Total Dissolved Solids (TDS) of a solution, i.e. the concentration of dissolved solid particles.
Working:
When voltage is applied between electrodes, the ions become charged and moving, thus constituting an electrical current. TDS meters monitor the amount of current that passes between the electrodes as a measure of the number of ions in a solution.

We are thus using thermostat and TDS meter to measure and control temperature and salinity to get a better yield.

Fixed-Off Bottom Method

Picture showing how a seaweed line is typically suspended in the Off-bottom Method.

In fixed off bottom method a 3 mm thick polypropylene rope 5 meters long is firmly stretched between two stakes. Attached to the 3 mm rope (line) are 30 pieces of raffia (polypropylene strings). Each of the planting material (seed), the size of the palm (150 grams), is tied to the raffia strings. The 3 mm rope, is suspended at least 20 to 30 cm from the sea bottom to prevent the growing seaweed from being tossed on the sand and 20 to 30 cm below the water surface at low tide to avoid the seaweeds from being exposed to direct sun light. Direct sun light will kill the exposed parts.
We have employed this method for our C-Cage
