    Voltage Sensor

     600
    Due to the current wide range of electronic products , power supply voltage is also different , in order to detect it needs a suitable voltage detection module and the controller. controller analog interface detects the input voltage up to 5V, ie greater than the voltage of 5V will not be detected.
    2014 latest voltage detection module can solve this problem and achieve greater than the voltage of 5V is detected , this module is based on the design principles of the resistor divider , make red terminal interface input voltage narrow five times , analog input voltage up to 5V , then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V ( 3.3V system, if used , can not be greater than the input voltage 3.3Vx5 = 16.5V). Because AVR chips used in 10 AD, so the simulation resolution of this module is 0.00489V (5V / 1023), so the minimum input voltage detection module detects voltage 0.00489V × 5 = 0.02445V.
    By 3P sensor cable plugged into the sensor expansion board , not only can easily detect the size of the battery voltage , monitoring interactive media works or battery-powered robot power, can also display the voltage produced by the voltage monitor IICLCD1602 LCD module .
    Product parameters:
    1, the voltage input range : DC0-25V
    2 , the voltage detection range : DC0.02445V-25V
    3, the voltage analog resolution : 0.00489V
    4, DC input interface : red positive terminal connected to VCC, GND negative pole
