Objective:
Do drying apparatus connections.
Some changes are made as we decided earlier,
- Use SSR
- Add five temperature and humidity sensors,1 at exhaust fan 3 inside the apparatus and 1 near heater so that it can sense the temperature and humidity of air coming from the heater.
- Current Indicator
- And made some program changes.
A switched-mode power supply (SMPS) is an electronic circuit used to converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state.
Switching power supplies have high efficiency and are widely used in a variety of electronic equipment, including computers and other sensitive equipment requiring a stable and efficient power supply.
A switched-mode power supply is also known as a switch-mode power supply or switching-mode power supply.
Here we used SSR because a solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. SSRs consist of a sensor which response to an appropriate input (control signal), a solid state electronic switching device which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this switch without mechanical parts. The relay may be designed to switch either AC or DC to the load. It serves the same function as an electromechanical relay but has no moving parts.
Conclusion:
I did connection and started the first trial on water.
Next Plan:
Start trials on another substrate.
