In one project that ran from a 9v battery and had no on/of switch, in order to monitor the battery voltage i used a voltage divider comprising two 4.7m resistors (and the 0.1uf capacitor), so as to keep the current consumption of the voltage divider to less than 1ua. Vout = (r2 / (r1 + r2)) * vin = (4.7kω / 26.7kω) * 16.8v = 2.95v

A very common and useful series resistor circuit goes by the nickname voltage divider. This applies to all electrical circuits;

(This Approach Provides Very Accurate Energy Consumption Estimates).

Easy solution is a voltage divider to 5v (or 4v to be on the safe side) and analog inputs. The analog to digital converter of the microcontroller is connected to the center tap of the divider so that tap voltage can be measured. The best example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage taken from a point between them.

In The Ideal Voltage Divider Math Above, We Calculated The Output Voltage As A Function Of The Input Voltage V In And The Voltage Divider Ratio F = R 2 R 1 + R 2 Only.

In electronics, a voltage divider is a passive linear circuit that produces an output voltage that is a fraction of its input voltage. It's output voltage is a fixed fraction of its input voltage. Level down voltages but not leveling up.

P = U I = (12 V) (0.004 A) = 0.0 48 W.

To form a voltage divider, the sensor is connected in series with a known resistance, and known voltage is applied across the divider. It distributes the input voltage among the components of the circuit. A voltage divider is a simple series resistor circuit.

The Proposed Reference Can Generate A 0.8V Reference Voltage With A Minimum Supply Voltage Of 0.8V.

See the voltage divider diagram. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. A voltage divider circuit is a very common circuit that takes a higher voltage and converts it to a lower one by using a pair of resistors.

But This Calculation Assumed That The Same Current I Flowed Through Both Resistors R1 And R2.

To calibrate you'll need a multimeter. I = u / r = (12 v) / ((1000 ω) + (2000 ω)) = 0.004 a. Using digikey battery life calculator gives you an expected life of ~.
