- 220V AC
For the 12-24V DC option, a reliable DC-DC converter is used to provide a regulated 5V output. This ensures a stable power supply for the ESP8266-01 module. Additionally, the 3.3V rail, which is necessary for the proper functioning of the module, is obtained from a linear regulator powered by the 5V rail.
To guarantee the smooth operation of the power supply, both the 5V and 3.3V rails are equipped with noise filtering capacitors. These capacitors effectively suppress voltage ripple and high-frequency interference, providing clean and steady power to the ESP8266-01 module.
On the other hand, if you prefer the 220V AC option, a compact 220V/5V switch mode power supply is employed. This power supply option offers convenience and simplicity, effectively converting the mains AC voltage to a stable 5V output.
Noise Filtering Capacitors
One key component in the power supply setup for the ESP8266 IoT sensor timer is the noise filtering capacitor. This capacitor is responsible for reducing voltage ripples and filtering out high-frequency interference. By effectively suppressing these unwanted electrical fluctuations, the noise filtering capacitors ensure a reliable and stable power source for the ESP8266-01 module.
“The noise filtering capacitors play a vital role in maintaining a clean and uninterrupted power supply to the ESP8266 IoT sensor timer.”
