The 30A range Current Sensor Module ACS712 consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportiona..
This is a simple but very useful module
which uses a potential divider to reduce an input voltage by a factor of
5. The Voltage Sensor Module 25V allows you to use the analog input of a
microcontroller to monitor voltages much higher than it capable of
sensing.For example with a 0-5V analog inpu..
