Selecting components is one of the most essential and critical processes when designing any electronic system. Poor component selection can lead to many problems within the design, PCB layout, power budget, etc. In this article, we will discuss how to select a component for a low-power-optimized design. Resistor The power dissipated by a resistor is…
How to extend solar and battery power in a weather station
Experiment 2 Aim To run an MCU on low power mode, read the temperature, pressure, and humidity readings using AHT10 and BMP280 Sensors, and send the readings over wifi. Requirements MCU: ESP32-WROOM-32D (Generic Wi-Fi + Bluetooth + Bluetooth LE MCU module) Temperature/Humidity Sensor: AHT10 (Temperature and humidity sensor) Pressure and Altitude Sensor: BMP280(Absolute Barometric Pressure…
How to achieve longer MCU battery life with low power sleep mode
There are generally six power modes in an MCU: Run: In full run mode, an MCU consumes full current. This mode is best suited for applications where power efficiency is not essential. Doze: As we know, power increases proportionally to the frequency. Therefore, we can conclude that higher clock speeds tend to higher power consumption.…
What is a low power design?
Low power design is a system using a collection of techniques and methodologies for the purpose of optimizing battery life and reducing the overall power dissipation of the system. To optimize the power there are many low power techniques that depend on the level of the design selected, ranging from semiconductor technology to the higher…
