Water Sensors

100% brand new and high quality

Size: 25mm×13mm/0.98″×0.51″(approx)

This module is based on principle of resistive voltage divider design,

can make the red terminal connector input voltage to 5 times smaller.Arduino analog input voltages up to 5 v,

the voltage detection module input voltage not greater than 5Vx5=25V

(if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).

Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023),

so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.

Voltage input range : DC0-25 V

Voltage detection range : DC0.02445 V-25 V

Voltage analog resolution : 0.00489 V

Output Interface : “+ ” connected 5/3.3V, “-” connected GND, “s” connected Arduino AD pins

DC input interface : red terminal positive with VCC, negative with GND

By 3P connector, connect this module with the expansion of board Arduino,
