Here are my project details as requested.
Capacitive Soil Moisture Sensor
Voltage: 3.3v - 5v
3v Analog Signal
The sensor will only measure the humidity of the project, initially we will use a so-called digital LED to test the integrity of the device.
DHT 11 (Air humidity and temperature sensor)
Voltage: 3.3v - 5.5V DC
In this case I will work with a different so-called, in the future this information will be connected to an application, using so-called analogues. and a bluetooth module
5v 2 channel relay
Voltage: 5v
Digital signal
The relay will work in conjunction with the security system, we will use a submersible pump and a fan that will be activated for security and temperature control.
5v source to power the water pump
9v source for the arduino.
