The Problem :

Weather stations are great for monitoring temperature, humidity, and other conditions, but many hobbyists face issues with low voltage power supply. If the voltage drops below the required level, sensors and microcontrollers like Arduino can malfunction, leading to inaccurate data.

The Solution :

The easiest solution is to use a DC-DC boost converter that steps up the voltage to a stable level. For instance, if you’re powering your weather station with a 3.7V lithium-ion battery, but the system needs 5V, a boost converter like the MT3608 module can maintain the required output.

Practical Example :

Imagine using a DHT11 sensor with an Arduino for your weather station. If your 3.7V battery starts dropping below 3.3V, the sensor may give faulty readings. Adding a boost converter ensures the voltage stays steady at 5V, keeping the system running smoothly.

Simple Calculation :

To calculate the current required:

• Power consumption of Arduino + DHT11 = 50mA

• Efficiency of the boost converter ≈ 90%

Required input current = (50mA / 0.9) ≈ 55.5mA
