Hall Current Sensor Module-ACS712 5Ampere
This module allows the measurement of moisture through analog output pins and it provides a digital output when a threshold of moisture is exceeded. The module is based on the LM393 op amp.
It includes the electronics module and a printed circuit board that “collects” the rain drops. As rain drops are collected on the circuit board, they create paths of parallel resistance that are measured via the op amp.
Current Sensor Module-ACS712 20 Ampere
This module is based on a 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 5 V x 5 =25 V (if using a 3.3V systems, input voltage not greater than 3.3 V x 5=16.5 V).
