DIY Electronic Bricks Voltage Detection Sensor Module for Arduino
The voltage detection sensor module adopts resistance divider to reduce the voltage£¬ so that the ADC pin of Arduino board can measure the voltage value after reduction and then work out the voltage value needs to be measured; High-precision sampling resistance£¬ precision: 0.5%£¬ temperature coefficient: 50PPM; Easy to use; Standard electronic brick interface; High accuracy£¬ measurement accuracy: <= 1%; Measurement range is up to 25V DC; 4 M2 screw mounting holes for easy installation. Note: Range <= ADC reference voltage / 0.18
