Low Voltage Smart Thermometer Power Design Tips
The Problem: Powering Low Voltage Smart Thermometers Smart thermometers, especially those built with microcontrollers like ESP32 or ATtiny85, are highly sensitive to unstable power. These devices often run on batteries or USB supplies, and any voltage fluctuation can lead to inaccurate readings or unexpected resets. This is a major issue for DIYers creating …
Low Voltage Smart Speaker Power Reference Guide
The Problem: Low Voltage Power Reference in Smart Speakers Smart speakers are compact and power-sensitive. A common challenge is maintaining a stable low-voltage reference (like 3.3V or 5V) for the audio amplifier or microcontroller. If the power dips or fluctuates, the speaker might reboot or distort audio. 
The Solution: Use a …
Low Voltage Industrial Sensor Power Design: A Beginner’s Guide
Industrial sensors such as proximity sensors, temperature modules, and IR detectors often operate at low voltages (3.3V or 5V). However, if the power supply is unstable or noisy, these sensors may malfunction, leading to inaccurate readings or total failure. The Problem : Many hobbyists and engineers connect sensors directly to a microcontroller’s 3.3V …
