Build a project briefTechnical tools
IoT battery-life calculator
Estimate battery life for a device with sensors and a radio. Compare consumption during sensor measurement, data processing, radio activity and sleep.
Calculate battery lifeVoltage-divider calculator
Calculate divider output voltage, current and resistor power. Check how a resistive load and resistor tolerances affect your circuit.
Check a voltage dividerI²C pull-up resistor calculator
